Abstract

L'invention concerne une machine de travail à piston oscillant comprenant des blocs de cylindre externe (1), des blocs de cylindre interne (2), des pistons (3), des têtes de cylindre (4) et des arbres de bloc-cylindres (5). Les multiples blocs de cylindre externe (1) sont co-cylindriques ou co-circulaires. Une forme globale du bloc cylindre interne (2) est approximativement circulaire, cylindrique, similaire à un rouleau ou similaire à un moyeu. Chaque bloc de cylindre externe (1) et un bloc de cylindre interne (2) définissent un cylindre incurvé (10). Le piston (3) est disposé dans le cylindre (10). Le piston (3) divise le cylindre en deux parties. Une section radiale du piston (3) se présente sous la forme d'un trapèze comprenant deux bases incurvées. Dans un plan axial d'une surface d'extrémité externe du piston (3), un contour est incurvé. Une surface d'extrémité externe du bloc de cylindre interne (2) est pourvue d'un arbre oscillant (21). L'arbre oscillant (21) est relié à une tige de liaison (52). Un élément de série de corps principal (333) est relié à une broche (54) au moyen des arbres oscillants (21), des tiges de liaison (52) et d'un vilebrequin (53). La machine de travail à piston oscillant a une densité élevée de puissance, ne nécessite pas de segment de piston, génère peu de frottement et a un rendement élevé, est refroidie uniformément et est de petite taille, présente une structure simple et possède une longue durée de vie.
