Abstract

Pompe comprenant une chambre (9) de compression communiquant avec une source de fluide à comprimer et un piston (1) mobile en translation pour assurer la compression du fluide dans la chambre (9) de compression, le piston (1) comprenant une tige (2) de piston s’étendant selon une direction longitudinale et munie à une de ses extrémité d’une tête (3) destinée à assurer la compression de fluide dans la chambre (9) de compression, la tête (3) comprenant au moins un joint (5) ou segment coopérant en contact étanche avec une paroi de la chambre (9) de compression, caractérisée en ce que le au moins un joint (5) est un joint à structure annulaire fermée disposé sur la surface périphérique de la tête (3) et qui est bloqué selon la direction longitudinale respectivement via deux butées longitudinales dont l’une au moins est un anneau (14) de blocage ouvert disposé dans une gorge (4) périphérique formée sur la périphérie de la tête (3 Figure de l’abrégé : Fig. 1Pump comprising a compression chamber (9) communicating with a source of fluid to be compressed and a piston (1) movable in translation to ensure the compression of the fluid in the compression chamber (9), the piston (1) comprising a rod ( 2) of a piston extending in a longitudinal direction and provided at one of its ends with a head (3) intended to ensure the compression of fluid in the compression chamber (9), the head (3) comprising at least one seal (5) or segment cooperating in sealed contact with a wall of the compression chamber (9), characterized in that the at least one seal (5) is a seal with a closed annular structure arranged on the peripheral surface of the head ( 3) and which is blocked in the longitudinal direction respectively via two longitudinal stops, at least one of which is an open blocking ring (14) disposed in a peripheral groove (4) formed on the periphery of the head (3 Figure of the Abstract: Fig. 1
