Abstract:
1. A valve, comprising: a housing having a low pressure fluid port, a high pressure fluid port, and a common port; and a valve element situated within the housing between the ports, the valve element having a body and a generally flat control wall with first and second surfaces, the control wall included in the body, a first flow path extending through the body and along the first surface of the control wall and coupling the low pressure fluid port to the common port, and a second flow path extending along the second surface of the control wall and coupling the high pressure fluid port to the common port, the valve element further having a contact member normally bearing against a valve seat associated with the second flow path so as to occlude the second flow path, the contact member being responsive to high pressure at the high pressure fluid port so as to move away from the valve seat and thereby open the second flow path, the control wall flexing into the first flow path in response to such opening.
