Title
(EN) HIGH PRESSURE DIESEL FUEL PUMPS USING A TWO-PIECE PUMP PLUNGER
(FR) POMPES A COMBUSTIBLE POUR DIESEL A HAUTE PRESSION AVEC PLONGEUR DE POMPE EN DEUX PARTIES
Abstract
(EN)
A fuel pump includes housing (1) having a fuel passage (47, 48) connectable to a source, fuel supply chamber (38) communicating with the passage, pump cylinder (2), plunger (3) reciprocable in the cylinder at a clearance and defining at one end, a pump chamber (8) open at one end for discharging fuel during a pump stroke and for fuel intake during a suction stroke. The plunger includes piston (121) and push rod (128) concentrically located within the piston, and fixed thereto to preclude axial movement. Head portion (123) on the push rod extends beyond piston (121) and engaged by a plunger actuator to cause a pumping stroke, and stem portion (130) in radial clearance with the piston (121) and engaging piston (121) at the other end. Force of the plunger actuator is transferred by the push rod directly and only to the other end of the piston, thus precluding placing the one end of the piston under compression and maintaining the clearance.
(FR)
Une pompe à combustible comprend un corps (1) présentant un passage pour le combustible (47), (48) qui peut être relié à une source, une chambre d'alimentation en combustible (38) qui communique avec le passage, un cylindre de pompe (2), un plongeur (3) capable de mouvement alternatif dans le cylindre avec un jeu et définissant à une extrémité une chambre de pompe (8) ouverte à une extrémité pour l'évacuation de combustible pendant une course de pompage et pour l'admission de combustible pendant une course d'aspiration. Le plongeur comprend un piston (121) et une tige de poussoir (128) disposée en position concentrique à l'intérieur du piston et fixée à celui-ci afin d'empêcher son déplacement axial. La partie de tête (123) de la tige de poussoir s'étend au-delà du piston (121) et elle se met en prise avec un dispositif d'actionnement du piston pour réaliser une course de pompage, et la partie de tige (130) présente un jeu radial avec le piston (121) et se met en prise avec le piston (121) à l'autre extrémité. La force du dispositif d'actionnement du plongeur est transférée directement et uniquement à l'autre extrémité du piston par la tige de poussoir, ce qui empêche la compression de l'extrémité du piston et conserve le jeu.
