Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 高圧の吐出冷媒ガスが可動スクロールのスラ スト受面において、吸入室に多量に漏れ出て圧縮機の圧 縮効率を低下することがない。 【解決手段】 本発明のスクロール型圧縮機において は、可動スクロール7の端板部7aの背面に設けられた 背圧用ポケット7eと作動室11とを連通するために、 可動スクロールの端板部を貫通して連通孔7fを設ける と共に、この連通孔に背圧用ポケットから作動室への冷 媒の漏れを阻止する逆止弁を設けている。また連通孔 は、圧縮途中の冷媒が背圧用ポケットに導入されるよう な位置で、作動室に連通している。 (57) [Problem] To prevent a large amount of high-pressure discharge refrigerant gas from leaking into a suction chamber on a thrust receiving surface of a movable scroll, thereby reducing the compression efficiency of a compressor. SOLUTION: In the scroll compressor of the present invention, in order to communicate a back pressure pocket 7e provided on the back surface of an end plate portion 7a of a movable scroll 7 with a working chamber 11, A communication hole 7f is provided through the end plate portion of the movable scroll, and a check valve for preventing leakage of the refrigerant from the back pressure pocket to the working chamber is provided in the communication hole. The communication hole communicates with the working chamber at a position where the refrigerant being compressed is introduced into the back pressure pocket.
