Rotary Hydraulic Vane Pump With Undervane Passages For Priming
US Patent:
4386891, Jun 7, 1983
Filed:

Appl. No.:
6/256722
Inventors:
Richard P. Riefel - Saginaw MI

International Classification:
F04C 200, F04C 1500
US Classification:
418 81
Abstract:
A balanced vane type hydraulic pump has a thrust plate and a pressure plate which cooperate with a cam ring, rotor and vanes to provide a plurality of pump chambers. During pump operation, fluid trapped under the vanes flows from under the vanes at the discharge port, as the vane recedes, to under the vanes at the inlet port to assist vane extension and improve pump priming. The undervane fluid passes through grooves in both plates with the groove in the pressure plate being in communication with the discharge flow of the pump. The grooves incorporate restrictions to the undervane fluid flow between the discharge and inlet positions of the vanes with the restriction in the thrust plate permitting more fluid flow than the restriction in the pressure plate to ensure that most of the fluid will pass through the rotor under the vanes in the inlet position to assist in vane extension.
