Title
(EN) AXIAL PUMP ASSEMBLIES
(FR) ENSEMBLES POMPES AXIALES
Abstract
(EN)
Axial pump assemblies for a hydraulic tool include a reciprocating element (102) that is configured to move between a retracted position and an extended position, a cam surface (114) in the reciprocating element (102) that can engage cam followers (108), a rotating element (104) that can receive rotational input, and a base (110) that can at least partially surrounds the rotating element (104). Movement of the cam followers (108) along the cam surface (114) can move the reciprocating element (102) from the retracted position to the extended position.

Des ensembles pompes axiales pour un outil hydraulique comprennent un élément à mouvement alternatif (102) qui est conçue pour se déplacer entre une position rétractée et une position étendue, une surface de came (114) dans l'élément à mouvement alternatif (102) qui peut venir en prise avec des suiveurs de came (108), un élément rotatif (104) qui peut recevoir une entrée de rotation, et une base (110) qui peut entourer au moins partiellement l'élément rotatif (104). Le mouvement des suiveurs de came (108) le long de la surface de came (114) peut déplacer l'élément à mouvement alternatif (102) de la position rétractée à la position étendue.
