A fluid valve is provided including a housing having an entrance 30 to permit flow of fluid into the housing and an exit 36 to permit said fluid to flow out of the housing. A first member 70 is disposed in the housing and defines at least one first passageway 80. A second member 74 is disposed in the housing and defines at least one second passageway 82. The first member and the second member are disposed in the housing operatively between the entrance and the exit so that the at least one first passageway and the at least one second passageway are selectively positionable with respect to each other to allow passage of the fluid through the at least one first passageway and the at least one second passageway from the entrance to the exit. A check valve 94 is disposed in the housing operatively between the entrance and the first and second members. The check valve is configured to permit fluid flow from the entrance to the first and second members and to prevent fluid flow from the first and second members out of the housing by the entrance. |
