Abstract

A manifold for a hydraulic system including a pump and accessories such as valves and filters as well as gauges in which the manifold is made part of the pump in fluid communication with the 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 having a pressurized fluid delivery portion, a pressure relief valve and at least one component from a group comprised of a filter and a fluid control valve, said manifold comprising:

a pump mounting portion having an inwardly extending cavity adapted to receive the pressurized fluid delivery portion of said pump;

a first component mounting portion for mounting said one of a filter and directional control valve;

an inlet passage communicating fluid from said cavity to said first component mounting surface;

a pair of fluid ports in the manifold;

a pair of passages, each of said pair of passages extending between said first component mounting portion 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 mounted to said manifold to said pressure relief valve in the return passage.

2. The manifold of claim 1, wherein the component is a directional valve.

3. The manifold of claim 1, wherein the component is a filter.

4. The manifold of claim, 2, wherein the manifold further has a filter mounting portion fluidly connected to said inlet passage.

5. A manifold for a hydraulic system having a pump having a pressurized fluid delivery portion, a pressure relief valve and a filter, said manifold comprising:

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

a filter mounting portion for mounting said filter;

an inlet passage communicating fluid from said cavity to said filter mounting portion;

an outlet port;

an outlet passage extending from the filter mounting portion to the outlet port;

a return passage extending between said inlet passage 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.

6. The manifold of claim 5 further comprising a top surface having said pump mounting portion.

7. The manifold of claim 5 further comprising an end surface having said pump mounting portion.
