Title (EN) RECIPROCATING COMPRESSOR
(FR) COMPRESSEUR ALTERNATIF
(KO) 왕복동식 압축기
Abstract: front page image
(EN)The present invention relates to a reciprocating compressor, comprising: a front housing and a rear housing; a cylinder block which is interposed between the front housing and the rear housing, and which has a plurality of cylinder bores; a piston accommodated in the cylinder bores such that the piston reciprocates; a driving shaft which rotates relative to the front housing; piston-driving means interconnected between the piston and the driving shaft; a valve plate opposite the bottom of the piston and having an inlet port and an outlet port; and a suction chamber and a discharge chamber formed in the rear housing. The rear housing includes: an outer rear housing having an inlet port for the introduction of a refrigerant from the outside; and an inner rear housing which is interposed between the outer rear housing and the cylinder block, wherein the suction chamber is formed between the outer rear housing and the inner rear housing, and the discharge chamber is formed between the cylinder block and the inner rear housing. The reciprocating compressor according to the present invention divides the rear housing into the outer rear housing and the inner rear housing to form the suction chamber between the outer rear housing and the inner rear housing, and thus enabling the uniform introduction of the refrigerant into the plurality of cylinder bores.
(FR)La présente invention concerne un compresseur alternatif, comportant : un carter avant et un carter arrière ; un bloc-cylindres qui est interposé entre le carter avant et le carter arrière et qui présente une pluralité d'alésages de cylindres ; un piston logé dans les alésages de cylindres de telle sorte que le piston puisse aller et venir ; un arbre moteur qui tourne par rapport au carter avant ; un moyen d'entraînement de piston interconnecté entre le piston et l'arbre moteur ; une plaque de soupape faisant face au bas du piston et dotée d'un orifice d'entrée et d'un orifice de sortie ; ainsi qu'une chambre d'aspiration et une chambre de refoulement formées dans le carter arrière. Le carter arrière comprend : un carter arrière extérieur doté d'un orifice d'entrée destiné à l'introduction d'un agent frigorigène en provenance de l'extérieur ; et un carter arrière intérieur qui est interposé entre le carter arrière extérieur et le bloc-cylindres, la chambre d'aspiration étant formée entre le carter arrière extérieur et le carter arrière intérieur, et la chambre de refoulement étant formée entre le bloc-cylindres et le carter arrière intérieur. Le compresseur alternatif selon la présente invention divise le carter arrière en carter arrière extérieur et carter arrière intérieur pour former la chambre d'aspiration entre le carter arrière extérieur et le carter arrière intérieur, permettant ainsi l'introduction uniforme de l'agent frigorigène dans la pluralité d'alésages de cylindres.
(KO)본 발명은 왕복동식 압축기에 관한 것으로서, 전방 하우징 및 후방 하우징과, 상기 전방 하우징과 후방 하우징 사이에 배치되며 복수개의 실린더 보어를 가지고 있는 실린더 블럭과, 상기 실린더 보어에 왕복이동이 가능하게 수용되는 피스톤과, 상기 전방 하우징에 대하여 회전하는 구동축과, 상기 피스톤과 구동축 사이에 연결된 피스톤 구동수단과, 상기 피스톤의 바닥에 대향하여 설치되며 흡입구와 토출구가 형성된 밸브 플레이트와, 상기 후방 하우징에 형성되는 흡입실과 토출실을 포함하여 구성되는 왕복동식 압축기에 있어서, 상기 후방 하우징은, 외부로부터 냉매가 유입되는 유입구가 형성된 외측 후방 하우징; 및 상기 외측 후방 하우징과 실린더 블록 사이에 개재되며, 상기 외측 후방 하우징과의 사이에서 상기 흡입실이 형성되고 상기 실린더 블록과의 사이에서 상기 토출실이 형성되는 내측 후방 하우징을 포함하는 것을 특징으로 한다. 본 발명에 따른 왕복동식 압축기에 의하면, 후방 하우징을 외, 내측 후방 하우징으로 분리시킴에 따라, 외측 후방 하우징과 내측 후방 하우징 사이에서 별도의 흡입실을 형성하게 되고 이에 따라 다수의 실린더 보어로 균일하게 냉매를 유입시킬 수 있는 효과가 발생한다.
