ABSTRACT:
An improved fluid bypass valve includes a valve housing having an inlet port, an outlet port and a bypass port, all of which are in fluid communication with a valve chamber within the valve housing. A shuttle having a fluid passage therein is disposed within the valve chamber and moves between a first travel limit position, in which fluid communication between the fluid passage and the bypass port is blocked and a second travel limit position, in which such fluid communication is permitted. First and second fluid seals are disposed in contact with interior surfaces of the valve housing on opposite sides of the bypass port, and the shuttle is disposed in sealing and sliding engagement with both the first and second fluid seals when the shuttle is in the first and second travel limit positions.
