FLOW PATH-SWITCHING VALVE, COMPRESSOR WITH FLOW PATH- SWITCHING VALVE, AND AIR CONDITIONER FOR MOUNTING ON MOTOR VEHICLE

摘要

To achieve energy saving, structures of a compressor and a flow path-switching valve that are used for an air conditioner for mounting on a motor vehicle are simplified by reducing their piping etc. In a head case (11) of a compressor body (10) for mounting on a motor vehicle, a high-pressure space (sp1) and a low-pressure space (sp2) are formed by a dome-like partition wall (11A) and a ring-like partition wall (11B), respectively. An I joint pipe (11C1) and an O joint pipe (11C2) are integrally molded. A flow path-switching valve (20) is built-in in the high-pressure space (sp1). Inside a case body (21) of the flow path-switching valve (20) is received a main valve (22). A main shaft (24) penetrates through the case body (21), main valve (22), and a valve seat (23) and is screwed to the head case (11). A low-pressure port (23c) is connected to the low-pressure space (sp2) through a communication opening (11a). A first and a second switching port of the valve seat (23) are connected to the I joint pipe (11C1) and the O joint pipe (11C2). The high-pressure space (sp1) and a high-pressure space of the flow path-switching valve are communicated through a first path (21a) of the case body (21).
