Title
(EN) VARIABLE CAPACITY COMPRESSOR
(FR) COMPRESSEUR À CAPACITÉ VARIABLE

Abstract
(EN)
The present invention relates to a variable capacity compressor. The variable capacity compressor, comprises: an intake seal, a crank seal and a discharge seal; a discharge outlet connected to said discharge seal and mounted to a discharge passage; and a check valve which opens and closes the discharge passage based on the pressure differentials in the intake seal, crank seal and discharge seal. Accordingly, the differential, between the check valve inlet and outlet pressures and the discharge pressure at the exit, are minimized by allowing the pressures of intake and crank seals to act upon the far-side of the valve body such that the pressure in the direction opposite to the discharge seal, is reduced.

La présente invention concerne un compresseur à capacité variable. Le compresseur à capacité variable comporte : un joint d'étanchéité d'admission, un joint d'étanchéité de manivelle et un joint d'étanchéité de refoulement; une sortie de refoulement reliée audit joint d'étanchéité de refoulement et montée sur un passage de refoulement, et un clapet anti-retour qui ouvre et ferme le passage de refoulement sur la base des différentiels de pression dans le joint d'étanchéité d'admission, le joint d'étanchéité de manivelle et le joint d'étanchéité de refoulement. Par conséquent, le différentiel entre les pressions d'admission et de sortie du clapet anti-retour et la pression de refoulement à la sortie est réduit à un minimum par le fait de permettre aux pressions des joints d'étanchéité d'admission et de manivelle d'agir sur le côté éloigné du corps de clapet de telle sorte que la pression dans la direction opposée au joint d'étanchéité de refoulement est réduite.

본 발명의 용량가변형 압축기는, 흡입실, 토출실 및 크랭크실이 형성되는 용량가변형 압축기에 있어서, 상기 토출실과 연결되는 토출유로; 상기 토출유로 내에 장착되며 토출실 압력과 크랭크실 또는 흡입실 압력의 차압에 의해 상기 토출유로를 개폐하는 체크밸브;를 포함하는 것을 특징으로 한다. 이에 따라, 토출실 압력에 반대방향으로 증감하는 크랭크실 또는 흡입실 압력을 밸브체의 소경부에 작용함으로써 체크밸브의 입구 측 토출압력과 출구 측 토출압력의 차이를 최소화하는 효과가 있다.
