Title (EN) SAFETY VALVE AND HIGH-PRESSURE PUMP COMPRISING SAID SAFETY VALVE
(FR) SOUPAPE DE SÛRETÉ ET POMPE HAUTE PRESSION COMPRENANT LADITE SOUPAPE DE SÛRETÉ
Abstract: front page image
(EN)A fuel safety valve arranged in a fuel supply line (7) between a low-pressure pump and a high-pressure pump (2), is provided with: a valve body (40) which defines a cylindrical cavity (41) having a longitudinal axis (A) and being connected to a duct (30), and a portion (42) of a discharge duct (33) in communication with the cylindrical cavity (41); a piston (44) sliding with respect to the valve body (40) in the cylindrical cavity (41) along the longitudinal axis (A); and a spring (46) housed in a variable-volume chamber (49) defined by a portion of the cylindrical cavity (41) between the piston (44) and a closure element (47); the piston (44) being provided with a through hole (52) supplied with the fuel leading into the variable-volume chamber (49), and the valve body (40) being provided with a fuel discharge hole (56) connecting the variable-volume chamber (49) to the discharge duct (33).
(FR)L'invention porte sur une soupape de sûreté à combustible agencée dans une ligne d'alimentation en combustible (7) entre une pompe basse pression et une pompe haute pression (2), laquelle soupape comporte : un corps de soupape (40) qui définit une cavité cylindrique (41) ayant un axe longitudinal (A) et qui est reliée à un conduit (30), et une partie (42) d'un conduit de décharge (33) en communication avec la cavité cylindrique (41) ; un piston (44) coulissant relativement au corps de soupape (40) dans la cavité cylindrique (41) le long de l'axe longitudinal (A) ; et un ressort (46) logé dans une chambre à volume variable (49) définie par une partie de la cavité cylindrique (41) entre le piston (44) et un élément de fermeture (47) ; le piston (44) comportant un trou traversant (52) alimenté en combustible conduisant à la chambre à volume variable (49), et le corps de soupape (40) comportant un trou de décharge de combustible (56) reliant la chambre à volume variable (49) au conduit de décharge (33).
