Title (EN) HYDRAULIC PUMP WITH ISOLATED COMMUTATOR
(FR) POMPE HYDRAULIQUE À COMMUTATEUR ISOLÉ
Abstract:
(EN) A hydraulic pump assembly includes a stationery pump body with a back panel, at least one compression chamber in the pump body, a piston slidably disposed in the compression chamber, an input shaft, an actuator means for reciprocating the piston according to a rotary input to the input shaft, and a commutator rotatably disposed in a central bore of the pump body to rotate according to the rotary input. The commutator defines a first inlet port for receiving hydraulic fluid from the compression chamber, a first outlet port for transmitting hydraulic fluid to the compression chamber, a second inlet port for receiving hydraulic fluid from the back panel, a second outlet port for transmitting hydraulic fluid to the back panel. The back panel includes an inlet fluid path in fluid communication with the second inlet port and an outlet fluid path in fluid communication with the second outlet port.
(FR) L'invention concerne un ensemble de pompe hydraulique, lequel ensemble comprend un corps de pompe stationnaire comprenant un panneau arrière, au moins une chambre de compression dans le corps de pompe, un piston disposé en coulissement dans la chambre de compression, un arbre d'entrée, des moyens formant actionneur pour faire effectuer un va-et-vient au piston en fonction d'une entrée rotative sur l'arbre d'entrée, et un commutateur disposé en rotation dans un perçage central du corps de pompe pour tourner en fonction de l'entrée rotative. Le commutateur délimite un premier orifice d'entrée pour recevoir un fluide hydraulique à partir de la chambre de compression, un premier orifice de sortie pour transmettre un fluide hydraulique à la chambre de compression, un second orifice d'entrée pour recevoir un fluide hydraulique à partir du panneau arrière, et un second orifice de sortie pour transmettre un fluide hydraulique au panneau arrière. Le panneau arrière comprend une trajectoire de fluide d'entrée en communication fluidique avec le second orifice d'entrée et une trajectoire de fluide de sortie en communication fluidique avec le second orifice de sortie.
