Abstract (en)
[origin: EP2511526A1] The reciprocating compressor has a lifting gripper (2) for periodically controlled open holding of a suction valve (1) over a specific crank angle area, where the lifting gripper is arranged at the automatic suction valve. An electromagnetic actuating unit (3) has a separated actuator (10) that serves for displacing the working stroke area of the used magnetic actuator (5) relative to its attack at the suction valve in the working area optimum for the used electromagnets.
