Abstract

L'invention concerne une machine à pistons oscillants présentant un carter (12), pourvu d'une paroi intérieure (32) de forme au moins approximativement sphérique, et au moins deux pistons (34, 36) qui peuvent tourner conjointement dans le carter (12) autour d'un axe de rotation (42) solidaire du carter et effectuent, lorsqu'ils tournent autour de l'axe de rotation (42, des mouvements oscillants alternatifs autour d'au moins un axe d'oscillation (44) perpendiculaire à l'axe de rotation (42), les mouvements oscillants des deux pistons (34, 36) étant dirigés en sens inverse et ces deux pistons (34, 36) présentant chacun une surface d'extrémité (46, 48) se faisant face et définissant chacune une extrémité frontale d'une chambre de travail (54), placée complètement à l'extérieur de l'axe de rotation (42) et dont le pourtour est délimité par une paroi de chambre de travail (58). Selon la présente invention, la chambre de travail (54), formée par les deux surfaces d'extrémité (46, 48) des deux pistons (34, 36) et la paroi de chambre de travail (58), ainsi que les pistons (34, 36) présentent la forme d'une section de bourrelet annulaire au moins dans la zone de leurs extrémités faisant face à la chambre de travail (54).
