Abstract: In a rotary flow-path exchanging valve, a high pressure side communicating groove 37 is provided to communicate a first exchanging port 23 and a second exchanging port 27 of a valve seat plate 5 with a high pressure side communicating port selectively. A part of a joint pipe 17 to be connected to the high pressure side port 19 is protruded into the high pressure side communicating groove 27. The protruding part constitutes a stopper pipe 20 for limiting the rotatable range of a valve element 1. In installing the stopper pipe 20, it is connected and secured to the high pressure side port 19 of the valve seat plate 5, and thereafter is hardened by plastic deformation processing. Thus, when the stopper pipe is heated by soldering for its securing to the valve seat 5, the necessary strength thereof can be maintained.

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.
