  • Press for compressing lubricating grease and the cartridges used therefor
    Patent number: 6467579
    Abstract: A press for extruding lubricating grease has a press head with a high pressure reciprocating pump, a high-pressure outlet opening with a check valve, a low-pressure intake opening for feeding the mass to be extruded to the reciprocating pump, and a connection on the press head for connecting a pipe thereto. The pipe receives therein a grease filled cartridge having a displaceable trailing piston. A cartridge-connecting element has a connection for the cartridge, and the pipe is open at that end thereof oriented away from the press head, whereby when the cartridge is connected to the cartridge-connecting element, it protrudes from the open end of the pipe, is guided radially by the pipe and is retained axially by the cartridge-connecting element.
