Title
(EN) RECIPROCATING ENGINE
(FR) MOTEUR ALTERNATIF
(JA) 往復動エンジン
Abstract
(EN) A reciprocating engine (1) having an annular top ring (5) as a first piston ring provided next to a top surface (head end surface)(4) of a piston (3) defining a combustion chamber (2), an annular second ring (6) as a second piston ring provided on the opposite side of the top surface (4) from the top ring (5), an annular gas chamber (7) defined by the top ring (5) and the second ring (6), and communication paths (8) for communicating the annular gas chamber (7) and the combustion chamber (2). The top ring (5) and the second ring (6) are individually inclined relative to the X-direction, in which the piston (3) reciprocates, so that they are separated from each other more on the thrust side (9) than on the anti-thrust side (10).
(FR) L’invention concerne un moteur alternatif (1) ayant un anneau supérieur (5) en tant que premier segment de piston placé près d’une surface supérieure (surface côté tête) (4) d’un piston (3) définissant une chambre de combustion (2), un deuxième segment de piston placé du côté opposé de la surface supérieure (4) de l’anneau supérieur (5), une chambre à gaz annulaire (7) définie par l’anneau supérieur (5) et le deuxième anneau (6) et des circuits de communication (8) destinés à faire communiquer la chambre à gaz annulaire (7) avec la chambre de combustion (2). L’anneau supérieur (5) et le deuxième anneau (6) étant tous deux inclinés par rapport à la direction X, dans laquelle le piston (3) alterne, de sorte qu’ils sont plus éloignés l’un de l’autre du côté poussée (9) que du côté anti-poussée (10).
(JA)  往復動エンジン1は、燃焼室2を規定しているピストン3のトップ面(頭部端面)4に隣接して配された第一のピストンリングとしての環状のトップリング5と、トップ面4に対してトップリング5を間にして配された第二のピストンリングとしての環状のセカンドリング6と、トップリング5とセカンドリング6とにより画成された環状ガス室7と、環状ガス室7と燃焼室2とを連通させる複数の連通路8とを具備しており、トップリング5及びセカンドリング6は、反スラスト側10よりもスラスト側9で互いに離反するようにピストン3が往復動するX方向に対して夫々傾斜している。
