A lubrication system includes a progressive distributor that is configured to dispense lubricant to a consumer. The lubrication system also includes a control device and at least one sensor that is configured to determine at least one lubricant pressure inside the lubrication system. The control device is configured to receive measured values from the at least one sensor and to recognize a lubrication cycle based on the measured values and also to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison.

Lubricating system

A lubrication system includes a progressive distributor and at least one pressure sensor. The progressive distributor includes a housing block having a lubricant inlet, a plurality of lubricant outlets, a plurality of piston bores fluidically connected to the lubricant inlet, each of the plurality of piston bores having a first outlet bore and a second outlet bore, and a metering piston in each of the plurality of piston bores. Each of the metering pistons is displaceable in a respective one of the plurality of outlet bores to uncover either the first outlet bore or the second outlet bore. The pressure sensor is disposed at an inlet of the progressive distributor upstream of the metering pistons with respect to a lubricant flow direction and configured to determine a lubricant pressure.

Lubrication system

A progressive distributor for lubricant includes a housing block. The housing block includes a lubricant inlet bore, via which receives lubricant, and a plurality of lubricant outlets, via which a metered amount of lubricant is dispensable. A plurality of metering pistons are provided in the housing block for the dispensing of the metered amount of lubricant. The metering pistons are received in associated piston bores. Each piston bore is associated with two lubricant outlets. Each metering piston is displaceable in the piston bore and is configured to alternatingly dispense the metered amount of lubricant to the one or the other lubricant outlet. The piston bores are fluidically connected to the lubricant-inlet bore and to each other via connecting bores to transfer lubricant to the other piston bores. The piston bore includes a first region configured to receive the metering piston and a second region configured as the lubricant outlet.

Progressive distributor

A progressive distributor for lubricant includes a housing block having an inlet and a plurality of outlets and a plurality of metering pistons received in associated piston bores in the housing block. Each piston bore is associated with two lubricant outlet bores, and each metering piston is displaceable and configured to alternatingly release the one or the other lubricant outlet bore in order to dispense the metered lubricant amount to the lubricant outlet bore. The piston bores are fluidically connected to the lubricant inlet bore and to each other via connecting bores in order to transfer lubricant to the other piston bores. A dummy piston is disposed in one of the piston bores that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass passageway that fluidically connects two of the connecting bores to each other.

Progressive distributor for lubricant

A progressive distributor includes a housing block with an inlet bore and outlet bores and first and second metering pistons in first and second piston bores. Each piston defines first and second annular workspaces and delimits first and second metering spaces at the ends of each piston, the first and second piston bores each having a central axis and being disposed one atop the other so that their central axes are parallel to each other and located in a central plane. Switching bores connect the metering spaces of the first metering piston to the workspaces of the second metering piston, and the switching bores are located on opposite sides of the central plane.
