Abstract

Ensemble de cylindre et piston pour compresseur; dans lequel un axe de piston traverse des trous formes dans des parois opposées du piston, le pourtour du piston présente, dans la région des trous, des évidements et le cylindre, sur toute sa longueur, entoure de tous côtés le piston. La course du piston est suffisamment grande pour que les évidements 16, en position de point mort bas du piston, sortent, au moins partiellement, du cylindre et que dans le piston 4 et/ou l'axe du piston sont prévus des passages de fuites 18, qui font communiquer les évidements avec l'espace 29 situé en arrière du piston. Application : compresseur, notamment de machine frigorifique.
