Title (EN) RECIPROCATING COMPRESSOR
(FR) COMPRESSEUR ALTERNATIF
(JA) 往復動圧縮機
Abstract:
(EN) In a reciprocating compressor in which a rocking piston mechanism is adopted, a lip ring is disposed between an outermost peripheral portion of a rocking piston and a cylinder, or the lip ring is disposed in an outer peripheral portion of the rocking piston closest to the cylinder when the rocking piston is rocking.
(FR) Dans un compresseur alternatif dans lequel un mécanisme à piston oscillant est adopté, une bague à lèvre est disposée entre une partie périphérique la plus à l'extérieur d'un piston oscillant et d’un cylindre, ou la bague de lèvre est disposée dans une partie périphérique externe du piston oscillant la plus proche du cylindre lorsque le piston oscillant oscille.
(JA) ロッキングピストン機構を採用した往復動圧縮機において、ロッキングピストンの最外周部とシリンダの間にリップリングを配置するか、ロッキングピストンが揺動時に最もシリンダに近接するロッキングピストンの外周部にリップリングを配置する。
