ABSTRACT:
A bi-stable electrically operated valve including a housing having inlet, outlet and return conduits, an intermediate conduit between the inlet and return conduits, a bi-stable electro-mechanical transducer having a flapper slidably mounting a first ball valve, first and second seats on the intermediate conduit, a third seat on the outlet conduit, the first and third seats being alternately engageable by the first ball valve to permit communication between the inlet and outlet conduits when the valve is open or between the inlet and return conduits when the valve is closed, a second ball valve, a piston for moving the second ball valve onto the second seat on the intermediate conduit, a conduit for effecting communication between the outlet conduit and the piston so as to cause the piston to drive the second ball valve onto the second seat when the inlet and outlet conduits are in communication, to thereby close off the inlet conduit from the return conduit, and a bleed opening between the inlet conduit and the intermediate conduit so as to provide equal pressure on opposite sides of the first ball valve when the valve is open and the first ball valve is on the first seat on the intermediate conduit.
