PROPORTIONAL VALVE, AIR-CONDITIONER COMPRESSOR ARRANGEMENT, AND OPERATING METHOD

摘要

Disclosed is an electromagnetically actuated proportional valve (1), in particular a differential pressure valve for use in CO2 air-conditioner compressor arrangements, comprising an electromagnetic actuator (3) for moving a valve body (2) in relation to a valve seat (5); a first pressure connection (7) via which a fluid can bypass the valve body (2) and flow to a second pressure connection (9) is associated with the valve seat (5). The valve body (2), which is preferably designed as a valve tappet, delimits a diffusor chamber (30) that is fluidically connected to the first pressure connection (7) via a fluid connection (22) delimited by the valve body (2) when the valve body (2) rests on the valve seat (5).
