Abstract

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.
