Abstract
A hydraulic module includes a pump housing with an opening in communication with an exterior surface of the pump housing. A plurality of pump chambers are in communication with the opening. A plurality of pump elements correspond to the plurality of pump chambers, each of the plurality of pump elements being movable within the respective one of the pump chambers to increase the pressure in a fluid from a suction side of the pump chamber to a pressure side of the pump chamber. A motor has an output member extending into the opening of the pump housing and coupled with the plurality of pump elements. A channel is formed in the exterior surface of the pump housing. The channel establishes fluid communication between the plurality of pump chambers.
