Abstract:
A fluid metering valve, comprising:an inlet fluid passage adapted to communicate with a pressurized fluid source for carrying pressurized fluid therein; a pressure sensor operable to detect a fluid pressure in said inlet fluid passage; an outlet fluid passage communicating with said inlet fluid passage; a valve seat disposed at a juncture of said inlet fluid passage and said outlet fluid passage; a valve member mounted for selective movement relative to said valve seat between a closed position for closing fluid communication between said inlet fluid passage and said outlet fluid passage and an open position for opening fluid communication between said inlet fluid passage and said outlet fluid passage to regulate a fluid pressure in said inlet fluid passage; and a pre-stressed bender actuator operatively engaging said valve member and operable to selective move said valve member to at least one of said open and closed positions in response a detected fluid pressure in said inlet fluid passage by said pressure sensor.
