Title (EN) ROLLER CAM FOLLOWER FOR A FUEL PUMP ASSEMBLY AND PUMP ASSEMBLY COMPRISING SUCH A ROLLER CAM FOLLOWER
(FR) GALET DE CAME À ROULEAUX POUR ENSEMBLE POMPE À CARBURANT ET ENSEMBLE POMPE COMPRENANT LEDIT GALET DE CAME À ROULEAUX
Abstract:
(EN) A roller cam follower (19) for a pump assembly for supplying fuel to an internal combustion engine, the roller cam follower comprising a cup-shaped cam follower body (20) having an end wall (22) configured for coupling with a piston (8) of the pump and a side wall (23) configured for coupling with a cylindrical seat formed in a pump body; and a roller (21), the roller being, on the one hand, contactable with a cam shaft (15) of the pump and, on the other hand, coupled to the cam follower body (20) on the opposite side of the end wall (20) with respect to the piston (8); the roller cam follower (19) comprising at least one bearing (33, 34) coupled, on the one hand, to the roller (21) and, on the other hand, to the cam follower body (20).
(FR) L'invention concerne un galet de came à rouleaux (19) destiné à un ensemble pompe permettant de fournir du carburant à un moteur à combustion interne. Le galet de came à rouleaux comprend un corps de galet de came (20) cupuliforme ayant une paroi terminale (22) conçue pour s'accoupler avec un piston (8) de la pompe et une paroi latérale (23) conçue pour s'accoupler avec un siège cylindrique formé dans un corps de pompe ; et un rouleau (21), le rouleau pouvant, d'une part, entrer en contact avec un arbre de came (15) de la pompe et, d'autre part, s'accoupler avec le corps de galet de came (20) sur le côté opposé de la paroi terminale (22) par rapport au piston (8) ; le galet de came à rouleaux (19) comprenant au moins un palier (33, 34) accouplé, d'une part, au rouleau (21) et, d'autre part, au corps de galet de came (20).
