Title (EN) OSCILLATING PISTON-TYPE COMPRESSOR
(FR) COMPRESSEUR DU TYPE À PISTON OSCILLANT
(JA) 揺動ピストン式圧縮機
Abstract:
(EN) In the present invention, two compressors (41, 51) are configured such that respective pistons (45, 55) thereof are in opposite phase to each other. Each piston (45, 55) has a non-circular outer circumferential shape, while each cylinder chamber (60, 70) has an inner circumferential shape determined on the basis of an envelope curve of the outer circumferential surface of the pistons (45, 55) when rotating. The compressor is provided with introduction units (67, 68, 163a, 164a) that introduce an intermediate pressure coolant to the compression chambers (75) of the respective compressors (41, 51).
(FR) La présente invention concerne deux compresseurs (41, 51) conçus de telle sorte que leurs pistons respectifs (45, 55) soient en opposition de phase l'un par rapport à l'autre. Chaque piston (45, 55) possède une forme circonférentielle externe non circulaire, pendant que chaque chambre (60, 70) de cylindre possède une forme circonférentielle interne déterminée sur la base d'une courbe d'enveloppe de la surface circonférentielle externe des pistons (45, 55) lors d'une rotation. Le compresseur est doté d'unités d'introduction (67, 68, 163a, 164a) qui introduisent un réfrigérant de pression intermédiaire dans les chambres de compression (75) des compresseurs respectifs (41, 51).
(JA) 2つの圧縮部(41,51)は、各々のピストン(45,55)の位相が互いに逆向きとなるように構成される。各ピストン(45,55)は、非円形の外周面形状を有する一方、シリンダ室(60,70)は、回転運動するピストン(45,55)の外周面の包絡線に基づいて定められる内周面形状を有する。圧縮機は、各圧縮部(41,51)の圧縮室(75)へそれぞれ中間圧の冷媒をそれぞれ導入する導入部(67,68,163a,164a)を備える。
