BULLET VALVE FOR CONTROLLED FLUID FLOWS

摘要

A valve (10) for selectively diverting flow from a source to another path for use in vehicles. The valve includes a valve plunger (20) axially movable in a housing (12) between a closed position in which an annulus (28) of the valve plunger blocks the inner diameter of an inlet pipe (14) and serves as a hydrodynamic surface to move the fluid entering the inlet pipe smoothly over the valve elements, including a control chamber (40) that contacts with a fixed base of the valve member. The control chamber is connected by an inlet orifice (32) to the inlet pressure and to an external control orifice (52) connection having a low-pressure side such that the control pressure in the control chamber is variable between 100% and 0% of the inlet pressure.

1. A valve assembly comprising:
a housing having an inlet and an outlet for selectively directing fluid from said inlet to said outlet; a chamber formed in said housing and having an inner diameter of said inlet, said chamber and said outlet; and a bullet valve portion movably positioned in said chamber and contained in said housing, wherein said bullet valve portion has an annulus portion configured to contact said inner diameter when said bullet valve portion is in a closed position and said annulus portion moves away from said inner diameter when said bullet valve portion moves to an open position.
