Description: |
| Abstract:
The invention relates to pump governors and more particularly to a governor for controlling the output of a rotary vane type hydraulic pump. The object of the invention is to provide a with a rod, which extends through a bore simple mechanism for automatically governing the eccentricity of the outer barrel of a vane type rotary hydraulic pump, so that the pressure of the fluid furnished by the pump will be substantially constant.
Claim:
The combination with a pump having a rotor provided with vanes and a barrel cooperating with said vanes and rotor to form a plurality of pumping compartments, said barrel being shiftable to vary the eccentricity of the pump, a support, a cylinder on said support and connected with the discharge of said pump, a piston working in said cylinder in response to discharge pressure and directly connected to said barrel to shift said barrel toward a position of zero eccentricity, a spring opposing the movement of said piston by the pressure fluid, means including a part of said piston to vary the tension of said spring and a member adjustably mounted on said support for limiting the eccentric position of said barrel. |
