A piston assembly (A) comprising a piston slave (18) having an interior wall, a piston (14) carried in the piston sleeve, a cup seal (16) carried by the piston which engages the interior wall of the piston sleeve, and a valve plate (12) matingly adapted to receive the piston sleeve. A firm thermal-insulating barrier (20) is disposed between the valve plate and the piston sleeve for reducing the heat flow from the valve plate to the piston sleeve.
On décrit un ensemble piston (A) comprenant un manchon de piston (18) muni d'une paroi intérieure, d'un piston (14) logé dans le manchon de piston, d'un joint calotte (16) solidaire du piston et placé au contact de la paroi intérieure du manchon de piston, et d'une plaque porte-soupape (12) adaptée pour recevoir le manchon de piston. Une barrière rigide d'isolation thermique (20) est disposée entre la plaque porte-soupape (12) et le manchon de piston pour réduire le flux de chaleur circulant de la plaque porte-soupape vers le manchon de piston.
