A seal carrier is provided for an ultrahigh-pressure fluid system having a plunger configured to reciprocate therein along a longitudinal axis when the ultra-high pressure fluid system is in operation, the seal carrier having an inner surface provided with a first portion configured to captively receive a seal, substantially preventing displacement of the seal in a direction substantially parallel to the longitudinal axis, and a second portion configured to circumferentially surround a bearing. The seal carrier is further provided with an outer surface having a recess formed along at least a portion of a circumference thereof, the recess at least partially positioned opposite the first portion of the inner surface along a lateral axis substantially perpendicular to the longitudinal axis.
L'invention concerne un support de joint qui est utilisé dans un système de fluide à ultra-haute pression comportant un piston qui effectue un mouvement de va-et-vient dans celui-ci le long d'un axe longitudinal lors du fonctionnement du système de fluide à ultra-haute pression, lequel support de joint comprend une surface interne possédant une première partie conçue pour recevoir un joint de manière captive, empêchant sensiblement le déplacement du joint dans une direction essentiellement parallèle à l'axe longitudinal, et une seconde partie conçue pour entourer de manière circonférentielle un pallier. Le support de joint comporte en outre une surface externe comportant un renfoncement formé au moins le long d'une partie de sa circonférence, le renfoncement étant en partie au moins disposé en face de la première partie de la surface interne le long d'un axe latéral essentiellement perpendiculaire à l'axe longitudinal.
