Abstract

Pompe de pressurisation de fluide (30) et système de pressurisation de fluide dans lesquels une fuite du fluide et une abrasion d'un bloc-cylindres (70) et d'une plaque d'orifice (45) peuvent être évitées en poussant le bloc-cylindres (70) vers la plaque d'orifice (45) avec une force de poussée appropriée. Une pompe hydraulique (30) inclut un bloc-cylindres (70) comportant une chambre de cylindre (73) qui peut être en communication avec un passage d'huile d'une plaque d'orifice (45) et dans laquelle est agencé un piston (61) ; et un mécanisme de poussée du bloc-cylindres (80B) qui applique au bloc-cylindres (70) une force de poussée qui pousse le bloc-cylindres (70) vers la plaque d'orifice (45). Le mécanisme de poussée du bloc-cylindres (80B) comporte un moyen de changement (80C) qui change la force qui pousse le bloc-cylindres (70) vers la plaque d'orifice (45).
