ABSTRACT:
A load sensed variable output gear pump system including a pump within a housing, an inlet passage extending to a pump inlet and an outlet passage extending from a pump outlet. A secondary outlet passage is located in the housing and a bypass outlet passage is located in the housing and is connected to a reservoir. A load sensed passage is located in the housing and is connected to load pressure. First and second independent control devices are provided for controlling flow through the secondary outlet passage from the outlet passage.
