Regulating valve system for adjustable wobble plate compressor for air conditioning system has regulator for determining choke valve opening based on external information such as cooling load

摘要

The system has a choke valve (11) in a cooling circuit, a constant pressure difference valve (12) designed to open when a pressure difference between upstream and downstream sides of the choke valve reaches a defined value, whereby compressor outlet gas passes to a crank chamber (1c), an external information detector (8) e.g. for cooling load or vehicle operating status and a regulator (13) for determining a choke valve opening based on the external information.
