Abstract
The compressor has a cylinder unit with a piston that moves in an oscillating manner in a cylinder housing, and a cylinder head with an inlet chamber. A switching valve interrupts an inlet flow of the cylinder unit. A control (130) activates the switching valve for operating the compressor in a lower part-load range. The control operates the valve in successive switching intervals which are shorter than a shortest time period after which a temperature of an evaporator (32) in an operating refrigerating system has risen during an interruption of the inlet flow.
