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 including a nozzle housing having an end connected to a solenoid housing and a fixed fluid flow directing tubular sleeve internal thereof and communicated to a supply port for receiving pressurized fluid therefrom. The sleeve includes a primary orifice communicating to a valve seat proximate the end of the nozzle housing and to a control port located proximate a second end of the nozzle housing via one or more longitudinal fluid passages between the nozzle housing and the sleeve. The sleeve includes a secondary bleed orifice located proximate the control port to bleed pressurized fluid thereto in a manner to provide more precise low pressure fluid control. A variable force solenoid actuated valve cooperates with the valve seat and receives pressurized fluid from the primary orifice to control flow of pressurized fluid to one or more exhaust ports as a means to regulate pressure at the control port in dependence upon electrical current to a coil of the solenoid actuated valve. The nozzle housing, fluid directing sleeve and valve seat are molded or cast as a one-piece component.
