Patent ID: 6997524

Claim:
A method for controlling a hydraulic system including a valve having a small orifice and a large orifice such that a fluid flows out through the small orifice and the large orifice comprising: generating a first pressure difference across the valve; bleeding off a small amount of a fluid at an upstream side of the valve thereby generating a pressure difference less than the first pressure difference at an onset of a pressure build across the valve; and opening the large orifice of the valve in response to said reduced pressure difference thereby preventing a high pressure difference across the valve and generating a maximum control pressure gradient; and generating a deswitch pulse from a controller to activate bleeding of said fluid, wherein generating said deswitch pulse further comprises generating said deswitch pulse in response to at least one of a signal that a bleed pulse is feasible and in response to a signal that a pressure drop across the valve can be sufficiently reduced without impacting system control.
