Abstract

A manifold (10) for a hydraulic system including a pump and accessories such as valves (42) and filters (88) as well as gauges in which the manifold is made part of the pump in fluid communication with the pump output to receive hydraulic fluid and deliver it to selected accessories and to return the fluid to the reservoir of the hydraulic system all with a minimum of hoses and couplings.

Claims

1. A manifold for a hydraulic system having a pump, one of a filter and directional valve and a pressure relief valve and an actuator, said manifold comprising:

an end face having an inwardly extending cavity adapted to receive a pressurized fluid delivering portion of said pump;

a mounting surface for mounting said one of a filter and directional valve;

a first passage communicating fluid from said cavity to said mounting surface;

a pair of fluid ports formed in the manifold;

a pair of passages, each of said pair extending between said mounting surface and one of said pair of ports;

a return passage extending between said cavity and a return port;

an aperture formed in said manifold to receive said pressure relief valve, said aperture being positioned to operably position said pressure relief valve in the return passage.

2. A manifold for a hydraulic system having a pump, an accessory for receiving and returning hydraulic fluid and a pressure relief valve, said manifold comprising:

an end face forming a cavity adapted to receive a fluid pressure delivering portion of said pump;

a mounting surface for supporting said accessory;

a fluid delivery passage communicating fluid from said cavity to said mounting surface;

a fluid return passage extending between said cavity and a return port; and

an aperture formed in a face of said manifold to receive said pressure relief valve, said aperture being positioned to operably position said pressure relief valve in said fluid return passage.

3. The manifold of claim 2 wherein said accessory is one of a filter and directional valve.

4. The manifold of claim 2 wherein said accessory is a fluid filter.
