Abstract: This disclosure relates to a method for operating a combined heat and power device, wherein carbon dioxide as a refrigerant (17) is compressed in a compressor, wherein the carbon dioxide is carried along a refrigerant circuit and routed back to the compressor via a collecting vessel (5).

Forces from the spring element are indirectly introduced into the drive shaft.

Abstract: A reciprocating piston engine, particularly a coolant compressor for motor vehicles, includes at least one piston movably supported in a cylinder. A pivot element in the form of a pivot ring is supported on a guide body attached to a shaft in an axially movable fashion such that the pivot element can execute a pivot motion. The pivot motion causes movement of the at least one piston. Spring forces of at least one return spring act on the pivot element in the direction of a start position in which the pivot element is pivoted at a starting pivot angle to a plane on which the rotary axis of the shaft stands upright. At least one further spring element acts on the return spring with an initial tension when the pivot element is in the start position.

Abstract: A safety device limits the pressure in an axial-piston compressor with variable piston displacement. The compressor has as wobble plate or swash plate whose tilt angle can be variably controlled by the pressure differential between the high pressure in the discharge pressure zone and the pressure in the piston-drive chamber. The safety device consists of a valve arranged in a connector channel between the discharge pressure zone and the pressure zone of the piston-drive chamber. When the discharge pressure exceeds a given pressure limit, the safety device responds by allowing an increased flow of pressure medium from the discharge pressure zone to the piston-drive chamber. The influx of pressure medium into the piston-drive chamber causes a reduction of the tilt angle of the swash plate or wobble plate.

Abstract: An air-conditioning system with a refrigerant medium circulating in a refrigerant loop has a variable-stroke compressor with a high-pressure outlet chamber, a drive chamber and an intake suction chamber. A first valve regulates a first flow of refrigerant medium from the high-pressure outlet chamber to the drive chamber, and a second valve regulates a second flow of refrigerant medium from the drive chamber to the intake suction chamber. The first and second valves operate independently of each other under the control of a control unit, and the variable stroke of the compressor is controlled by the first and/or second flow of refrigerant medium.
