A lubricant dispenser includes a lubricant container that has an outlet opening for lubricant, a piston disposed in the lubricant container, and a cap connected with the lubricant container, having a device for generating a gas that impacts the piston. The device for gas generation has a gas cell with an electrolyte fluid and electrodes for electrochemical gas generation, a power source, as well as an electrical connection between the power source and the electrodes with a switch. The cap is a plastic injection-molded part produced in one piece, formed from several parts, using the multi-component injection-molding method, which part is made of an outer ring made of insulation material and an insert that forms the gas cell, having two electrically conductive wall regions as electrodes, as well as having an intermediate piece that separates the conductive regions. The insert contains a sponge saturated with electrolyte fluid, and is closed off with a plastic lid.

Lubricant dispenser

A cell for gas generation is provided, particularly for the operation of a lubricant dispenser. The cell has two electrodes to be connected to a circuit containing a power source, and an aqueous electrolyte fluid located between the two electrodes, containing an azide having the formula XN, for electrochemical generation of a gas containing nitrogen (N). The electrolyte fluid contains a magnesium salt as an additive, for chemical binding of hydroxide ions that are formed during the electrochemical reaction.

Cell for gas generation

A device for lubricating a rolling bearing. The inventive device comprises a lubricant dispenser ( ) connected to the lubricating point of the rolling bearing ( ) and a measuring unit ( ) allocated to the rolling bearing ( ) for detecting the condition of the bearing. The lubricant dispenser ( ) comprises a lubricant container with a supply of lubricant ( ), a discharge device with an electromotor drive ( ) and a control device ( ) lined with the measuring device ( ). The control device ( ) of the lubricant dispenser ( ) emits control signals to the electromotor drive ( ) at certain intervals prompting it to discharge small amounts of lubricant and changes the discharge times and/or the duration of the discharge intervals if the measuring signal emitted by the measuring unit ( ) exceeds a defined value. In this case, a signal for displaying an incipient bearing defect is also emitted.

Device for lubricating a rolling bearing

A plurality of lubricant dispensers with respective microprocessor controllers are connected to a central microcomputer and can count up the number of revolutions of the respective spindle so that local lubrication at different sites of a machine will satisfy the site requirement even if the machine operation and lubrication have been interrupted. The controller of the dispenser includes a data store responsive to the dispensing time which is reset when a new reservoir is hooked up.

Method of and apparatus for lubricating an apparatus having a number of

A flowable lubricant is metered in pulses to a chain drive under the control of the computer programmed to respond to measurement of the chain drive speed so that, when the speed of the chain drive is below a threshold level above which centrifugal force can cause loss of lubricant, the lubricant can flow in pulses to the chain drive. When, however, the speed of the chain drive rises to the threshold value, the pulse dispenser is blocked and the supply of lubricant pulses is terminated. The lubricant pulses which are not supplied during the interval are stored. When pulse supply of lubrication is restored, the stored lubricant pulses are supplied.

Method of metering a flowable lubricant of a chain drive

An automatic lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected to a machine to be lubricated and an opposite side, a piston in the vessel movable forward toward the one side to force the lubricant from the outlet, and an electric drive connected to the piston and electrically energizable to advance the piston forward. An electric power source is connected via an electrical circuit to the drive for periodically energizing the drive and thereby advancing the piston an increment and pumping a dose of the lubricant from the outlet.

Electrically powered automatic lubricant dispenser

An automatic pressurizable lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected to a machine to be lubricated, a cover, and a cap fittable like a piston in the vessel and forming with the cover a substantially closed compartment holding a supply of a reactive liquid. The cover is formed with a seat opening into the compartment and extending along an axis and a removable partition closes the seat and segregates it from the liquid-holding compartment. A cartridge body fittable in the seat is movable therein between a partially inserted position and a fully inserted position and is formed unitarily of plastic with a cylindrical collar formed with a pair of diametrally opposite cutouts and having an outer end. The outer end moves from nonengagement with the partition in the partially inserted position to engagement through the partition in the fully inserted position. An element capable of reacting with the liquid and forming a gas is held by respective arms on the cartridge pivotal on the collar in the cutouts between holding and releasing positions. The arms each have an outer end formed with an inwardly directed retaining formation engaging the reactive element and holding same in the collar only in the holding position and an inner end engageable outwardly with the seat to pivot the respective outer end into the releasing position on movement of the body into the fully inserted position.

Automatic lubricant dispenser

A lubricant dispenser has a housing, a piston subdividing the housing into a pair of compartments one of which is generally closed and the other of which is adapted to be connected to a machine to be lubricated, a body of a reactive liquid in the one closed compartment, and a body of a fluent lubricant in the other compartment. The piston is movable against the lubricant body to force same from the housing to the machine. A reactive element in the one compartment can react with the liquid and form a gas when immersed in the reactive liquid to push the piston with the gas against the lubricant body and expel the lubricant from the housing. The reactive element is constituted as a coherent block by a multiplicity of particles of an active substance capable of reacting with the liquid and forming a gas on reaction therewith and a multiplicity of particles intermixed and in electrically conductive engagement with the active particles of a substance that is substantially less reactive.

Electrochemically reactive element for lubricant dispenser

A cartridge containing a current-generating cell and a gas-generating cell electrically connected therewith is received in a cylindrical seat of a bottom part of a unit fitting into an end of a lubricant receptacle housing and closing this end thereof. The lubricant receptacle housing can be connected by a fitting at the opposite end of a machine to be lubricated. The unit has a cover cap on its bottom part which can be forced off the latter when gas is generated in the unit to displace the lubricant out of the housing.

Lubricant dispenser with gas-controlled feed of lubricant to a machine

An automatic pressurizable lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected via a conduit to a machine to be lubricated and another open side and a cover engaged over the other side and fitted with a cap fittable snugly like a piston in the vessel and forming with the cover a substantially closed compartment holding a supply of a reactive liquid. The cover is formed with a seat opening into the compartment. A gas-generating cartridge fits into the seat and has an element capable of reacting with the liquid and forming a gas. A removable partition closes the seat and segregates it from the liquid-holding compartment. The cartridge is constructed so as to remove the partition and contact the element with the liquid for generating gas in the compartment and forcing the cap like a piston away from the cover into the vessel to pressurize the fluent lubricant therein.

A dispenser of a flowable medium, especially a lubricant, with a flexible wall tube forming the pumping chamber which is connected to a container for the flowable medium by a check-valve and feeds a dispensing nozzle. The pumping chamber is deformed by a plunger actuated by a lever in turn displaced by a solenoid whose linearly displaceable rod bears upon the lever.
