Publication number: 20240133517Abstract: 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.Type: ApplicationFiled: February 14, 2022Publication date: April 25, 2024Inventors: Jürgen KREUTZKÄMPER, Andreas SCHÖNFELD, Dennis ZAHN
