A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.

Portable chemical dispenser and method of using same

A bottle cartridge fits in the neck of a bottle providing liquid flow and venting from the bottle interior when operably connected to a dispenser, and preventing spills or leakages upon any bottle upset. Dual seals are provided; a valve core is operated by connecting the cartridge to a dispenser coupling. Cartridge materials are disclosed.

A proportioning dispenser of concentrated chemical mixed in a diluent such as water includes a water valve, an in-line water pressure regulator downstream of the valve and an eductor downstream of the regulator. When the valve is open, water flows to the regulator, and a pressure regulator water flow passes to the eductor. When the valve is closed, no water flows to the regulator, which sees pressurized water only when the water valve is open during a dispensing cycle. More accurate dilution ratios are achieved over a wide range of incoming water line pressures. In an alternate embodiment, a water valve and a regulator are formed in a common housing with the regulator operationally downstream of the valve.

Dispenser with inline pressure regulator

A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.

Multiple chemical product eductive dispenser

A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.

A remote activation dispensing apparatus for dispensing fluids. An actuating device positioned on a dispensing tube is operably connected to a flexible elongated member, which is operably connected to a valve in a dispensing unit. Upon manipulation of the actuating device, the valve is actuated for passing or cutting off fluids from the dispensing unit to the dispensing tube.

A purge valve for use with a chemical select valve comprises, in a preferred embodiment, an enlarged chamber in the vacuum impelled feed line to the select valve. The chamber is formed by resilient walls, collapsible upon vacuum operation to draw chemical into a venturi line where it is mixed with water and dispensed. The walls do not fully collapse and provide passages for chemical flow. Upon vacuum interruption, the chamber walls expand, returning the chamber to its larger volume and drawing chemical back upstream from common passages in the select valve. Another chemical can then be selected without contamination of the preceding chemical in the common passages.

An improved selector valve includes a sealing disc with a sealing face biased against an opposed sealing face of a port plate. The sealing disc has a channel located in the sealing face which communicates with an outlet port and a single selected inlet port on the port plate while simultaneously sealing off all other inlet ports. A venturi eductor has a suction passage sealed directly to the port plate outlet for connecting the venturi directly to a selected inlet port. A connection bridge spans a tolerance gap between the port plate to the eductor. The flow path of the fluid through the selector valve has been streamlined to eliminate stagnation points and minimize turbulent flow of the fluid. As a result, the dilution rate of the chemical and water being dispensed upon actuation of the valve is improved and purging of the selector valve is eliminated because the amount of residual chemical remaining in the selector valve is minimized. Moreover, the material selection of the sealing disc enables a wider temperature range of operation for the selector valve without thermal expansion or contraction which may detrimentally effect the seals between the adjacent proponents of the selector valve.
