Claim 10:
11. A progressive distributor for lubricant including a housing block,
wherein the housing block includes a lubricant inlet bore, via which lubricant is introducible into the progressive distributor, and a plurality of lubricant outlet bores, via which a metered quantity of lubricant is dispensable to a consumer connected to the respective lubricant outlet bore,
wherein for the dispensing of the metered lubricant amount a plurality of metering pistons are provided in the housing, which metering pistons are received in associated piston bores, wherein each piston bore is associated with two lubricant outlet bores, and the metering piston is displaceable in the piston bore and is 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, wherein furthermore the piston bores are fluidically connected to the lubricant inlet bore, and the piston bores are fluidically connected to each other via connecting bores in order to transfer lubricant to the other piston bores, and
wherein in at least one of the piston bores, a dummy piston is disposed that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass connection that fluidically connects two of the connecting bores to each other in order to direct lubricant past the dummy piston into the connecting bores leading to the next piston bore.
