Abstract
A variable displacement, rocker cam type, axial piston pump in which the rocker cam is driven by a stroking piston and the stroking piston is connected to the rocker cam by a pair of flexible connectors and tension in the first flexible connector is raised and tension in the second flexible connector is lowered when the stroking piston is moved in one direction to pivot the rocker cam toward a position of maximum fluid displacement and tension in the second flexible connector is raised and tension in the first flexible connector is lowered when the stroking piston is moved in the other direction to pivot the rocker cam toward a position of minimum fluid displacement.
