ABSTRACT:
A valve assembly in which the ends of a tube having a passageway extending therethrough are respectively mounted in cavities in separate housings each of which has a passageway communicating with its cavity. An elastic sleeve is placed about the adjacent ends of the housings and a path is formed in the housings that bypasses the tube. One housing is attached to its end of the tube so as to move therewith. An actuator is connected to the housings so as to position the other end of the tube against the bottom of the cavity in the other housing. This forms a seal that prevents fluid flow in the bypass. When the actuator is squeezed, the housings are moved apart so as to open the seal and permit a fast flow of fluid through the bypass.
