Pump device i.e. passive pump device, for conveying e.g. lubrication oil for refrigerating machine, has piston movable relative to cylinder, where fluid in fluid path of suction line is conveyable/pumped into pressure line over workspace
Pump device i.e. passive pump device, for conveying e.g. lubrication oil for refrigerating machine, has piston movable relative to cylinder, where fluid in fluid path of suction line is conveyable/pumped into pressure line over workspace
The device (15) has a pump piston arranged in a pump cylinder and movable relative to the pump cylinder in translation direction by oscillations of the pump cylinder in an oscillating manner. A suction line and a pressure line are coupled with a workspace in a flow-technical manner, where fluid in a fluid path of the suction line is conveyable/pumped into the pressure line over the workspace. Another suction line and another pressure line are coupled with another workspace in a flow-technical manner. An independent claim is also included for a refrigerating machine.
