摘要： A coolant compressor has a hermetically sealed compressor housing, in the interior of which lies a piston cylinder unit that compresses a coolant. The cylinder housing of the piston cylinder unit is closed at the front end thereof by a cylinder head. A linear drive is provided, comprising at least one oscillating body which is surrounded by an excitation winding and which is connected to the piston to move same along a longitudinal axis in an oscillating manner. The piston cylinder unit has at least one first permanent magnet that lies on the piston, and at least one second permanent magnet that lies on the cylinder housing. Both magnets face each other and are oriented in the same magnetic pole direction in order to generate a repelling effect between both magnets to limit the path of the piston in the region of the top or bottom dead center.

摘要： A pump drive assembly is disclosed. The assembly includes a driver, a pump drive member driven by the driver, and a decoupler that decouples the drive member from the driver when a force acting upon the drive member exceeds a threshold force. The pump drive member can be a piston rod, and the decoupler can be a magnet attached to the piston rod and coupled to a magnetically attracted plate driven by the driver. When a force resisting movement of the piston rod exceeds the magnetic force coupling the magnet to the plate, the magnet decouples from the plate, and the pumping operation ceases.
