Abstract:
A solenoid actuated valve for regulating the pressure of a pressurized fluid in a fluid control system in proportion to the current level of an electrical input signal, comprising a nozzle housing having a fixed fluid flow directing tubular sleeve internal thereof and communicated to a supply port for receiving pressurized fluid therefrom, said sleeve including a primary orifice that communicates to a valve seat and to a control port via at least one fluid passage between said nozzle housing and said sleeve and including a secondary bleed orifice thereon located proximate said control port, said control port communicating with an external fluid pressure actuated component, a variable force solenoid actuated valve that cooperates with said valve seat receiving pressurized fluid from the primary orifice to control flow of pressurized fluid to at least one exhaust port as a means to regulate pressure at the control port in dependence upon electrical current to a coil of the solenoid actuated valve, said secondary bleed orifice being disposed on said sleeve proximate said control port to bleed pressurized fluid to said control port in a manner to provide more precise low pressure fluid control.
