Filed:
Jul 19, 1995
Appl. No.:
8/504093
Inventors:

Abstract:
A hydraulic pump is disclosed which uses a side-discharge valve plate. The present valve plate includes a valve plate body having front and back surfaces with a side defining the peripheral surface therebetween. First and second fluid passages are formed on at least one of said front and back surfaces for respectively defining a fluid inlet for supplying hydraulic fluid to a piston and a fluid outlet for receiving pressurized hydraulic fluid from a piston. At least one fluid access is formed in the side of the valve plate body, connecting with at least one of said fluid passages to define a fluid pathway therewith. The design of the present invention thereby permits a pump design have shorter axial length, permitting a smaller size pump which offers improved space considerations. Also, the present valve plate also has few contact surfaces, thereby reducing leakage and improving pump efficiency.
