  • Patent number: 8353680
    Abstract: A stroke-adjustable air conditioning compressor, in particular for motor vehicles, including a drive mechanism for pistons that move back and forth, the pistons being driven by an adjusting plate, such as a pivoting plate, pivoting ring or swash plate at an adjustable pivoting angle. The position of the pivoting angle is influenced inter alia by compressive forces, inertial forces and elastic forces that are active in the drive mechanism.

  • Publication number: 20070256431
    Abstract: An air-conditioning compressor for air conditioning systems, especially for motor vehicles, or an air conditioning system comprising an air-conditioning compressor. The air-conditioning compressor is connected to a high-pressure zone and a suction pressure zone. Driving chamber pressure is redirected from the driving chamber of the air-conditioning compressor, i.e. from the high-pressure zone of the driving chamber to the suction pressure zone, if necessary while a filter, particularly a dirt particle filter, is optionally located in the suction pressure zone.
