Valve

Patent ·
OSTI ID:5074252
A valve device is described for controlling the flow of fuel to an internal combustion engine having a pressurized lubricating oil system associated therewith. The valve is adapted to be disposed in the fuel line between a fuel pump and the engine. The device comprises a valve body having a bore with an axis therein, a pair of fuel inlet passages in the body both simultaneously and continuously communicating with the bore and the fuel line, and means providing a valve seat between one of the inlet passages and the outlet passage. A valve means is disposed in the bore and is moveable axially therein for cooperation with the valve seat to close communication between the one inlet passage and the outlet passage. A balancing piston is disposed in sealing relationship with the bore between the other of the inlet passages and the outlet passage and is moveable axially in the bore. The device also comprises a means for connecting the piston and the valve means for transmitting fuel pressure forces acting on the piston to the valve means, and a means for transmitting movement of the pressure responsive means to move the valve means away from the valve seat when the pressure responsive means senses a predetermined pressure in the oil system.
