Patent ID: 7779863

Claim:
An asymmetric pressure control valve for regulating pressure within a servo system comprising: a valve body having an asymmetric configuration, such that a return valving component of said valve body comprises a greater size than a pressure valving component of said valve body, said valve body having return and pressure inlet and outlet ports formed therein for fluidly communicating with an interior cavity of said valve body; a return spool freely supported within an interior cavity of said return valving component of said valve body and configured to regulate fluid flow through said return inlet and outlet ports; and a pressure spool, independent of said return spool, and freely supported within an interior cavity of said pressure valving component of said valve body, said pressure spool configured to regulate fluid flow through said pressure inlet and outlet ports, said return spool being greater in size than said pressure spool and corresponding in size to said return valving component, said pressure spool corresponding in size to said pressure valving component.
