Abstract
This invention reduces the size of the solenoid section of the control valve and simplifies its mechanism. In particular, the invention is intended to enable the control of a variable capacity compressor. In the differential pressure section B.sub.1, a path is formed between a compressor's P.sub.c pressure introducing port 15c and a suction side. In this path a P.sub.c valve disc 17 is installed which engages with or disengages from a valve seat 15e.sub.2 formed in the path on the suction side of a valve opening 15e.sub.1. The P.sub.c valve disc 17 is urged by an adjust spring 20 to close the valve opening. In the solenoid proportional control section B.sub.2, a plunger chamber R.sub.3 is formed which has a P.sub.d pressure introducing port 15g. A plunger 24 is movably installed in the plunger chamber R.sub.3 and is fitted with a connecting rod 25, which passes through a through-hole 15d.sub.1 in the solenoid proportional control section B.sub.2, the P.sub.c pressure introducing port 15c and the valve opening 15e.sub.1 to contact the P.sub.c valve disc 17. A plunger spring 26, which has greater spring force than the adjust spring 20, is installed in opposition to the adjust spring 20. In the plunger chamber R.sub.3 is installed a P.sub.d valve disc 27which opens and closes the through-hole 15d.sub.1 as the plunger 24 moves in the plunger chamber R.sub.3.
