Claims (1)
縮機に内蔵された弁本体内の通孔に設けた弁座に
吸入圧力を受け動作する圧力応動部材により接離
し、弁本体に設けられたガイド内に摺動する弁体
を有する弁室と、弁体と接触し、吐出圧力を受け
る作動棒を有し、作動棒の外側に調整自在な調整
バネを設けてなることを特徴とする可変容量形圧
縮機の圧力調整弁。 The crank chamber and suction pressure chamber of the compressor are connected to each other by a pressure-responsive member that operates in response to suction pressure on a valve seat provided in a through hole in the valve body built into the compressor. The valve chamber includes a valve chamber having a valve body that slides in a guide, an actuation rod that contacts the valve body and receives discharge pressure, and a freely adjustable adjustment spring provided on the outside of the actuation rod. Pressure regulating valve for variable displacement compressor.
