Abstract: The present disclosure relates to a reciprocating-piston compressor (10), including a control device (12), which control device is designed to control a flow rate of the reciprocating-piston compressor (10), in particular in a continuously variable manner, and which control device has an input (18) for feeding input information, in particular suction pressure or high pressure of a corresponding compressor (10), and has at least one output (20) for controlling a control element (16), wherein the control device (12) is designed to generate a digital output signal, wherein the control element has a digitally controllable control valve (16), wherein the reciprocating-piston compressor (10) has at least one suction-gas volume (22) and at least one high-pressure volume (24), wherein a connection (26) is formed between the at least one suction-gas volume (22) and the at least one high-pressure volume (24) of the reciprocating-piston compressor (10), wherein the digitally controllable control valve (16) is arranged i

Abstract: A compressor for compressing a refrigerant comprising a cylinder block, a cylinder cover (12) and a valve plate (10) which is interposed between the cylinder block and the cylinder cover (12), said valve plate (10) being connected to the cylinder cover (12) and/or to the cylinder block without redundancy in the sealing plane.

Abstract: A system has a magnetic coupling for the no-contact transmitting of a torque from a first shaft coupled with a drive unit to a second shaft disposed in a housing. One of the shafts is provided with an inner rotor having magnets and the other shaft is provided with an outer rotor having magnets. The shaft driven by the drive unit is connected in an articulated manner with the drive-side rotor.
