Title
(EN) HYDRAULIC PUMP FOR A VEHICLE ENGINE
(FR) POMPE HYDRAULIQUE DE MOTEUR DE VEHICULE AUTOMOBILE
Abstract
(EN)
A hydraulic pump in the form of an oil pump (12) for a vehicle engine has both its pinion (21) which is driven by the engine's crankshaft (3), and a ring-gear (22) which cooperates with the pinion (21), incorporated in an end-cover (11) fastened to the end of the engine block (2). A cap (15) is inserted in a collar (14) on the side of the end-cover facing away from the engine and is only held in position there by means of a locking ring (17) which engages with a groove (16) in the collar and presses the cap (15) towards the engine. Outside the oil pump, a partly socket-shaped belt pulley (7) is mounted on the crankshaft (3) and its socket-shaped portion substantially grips the collar. Fitting and removal are thus simplified and engine overall length reduced. Simplified sealing also reduces oil leakage risks.
(FR)
Pompe hydraulique sous forme d'une pompe à huile (12) conçue pour un moteur de véhicule automobile et dont le pignon (21) actionné par le vilebrequin du moteur (3), ainsi qu'une couronne de train planétaire (22) coopérant avec le pignon (21), sont intégrés dans un couvercle d'extrémité (11) fixé à l'extrémité du bloc moteur (2). Une garniture (15) est introduite dans un collier (14) situé sur le côté du couvercle d'extrémité opposé au moteur et est maintenue en place uniquement par l'intermédiaire d'une bague de verrouillage (17) venant en contact avec une rainure (16) située dans le collier et poussant la garniture (15) contre le moteur. A l'extérieur de la pompe à huile, une poulie de courroie partiellement en forme de douille (7) est montée sur le vilebrequin (3) et ladite partie en forme de douille serre pratiquement le collier. Ce dispositif facilite le montage et le démontage et réduit la longueur totale du moteur. Le système d'étanchéité simplifié réduit également les risques de fuite d'huile.
