Abstract
Abstract A fluid switching apparatus for receiving fluids from a first plurality of source lines and a second plurality of source lines and for switchably routing the fluids from one of the pluralities of source lines to a plurality of output lines. In accordance with the invention there is provided a housing and a first plurality of flexible tubes having inlet and outlet ends, the tubes being mounted in the housing in substantially parallel relationship with the inlet ends of the tubes being adapted for coupling to the first plurality of source lines. A second plurality of flexible tubes having inlet and outlet ends are mounted in the housing in substantially parallel relationship and spaced from the first plurality of tubes with the inlet ends adapted for coupling to the second plurality of source lines. Means are provided for coupling the outlet ends of the first plurality of tubes to the outlet ends of the second plurality of tubes so as to form a plurality of common outlets, the common outlets being adapted for coupling to the plurality of output lines. An elongated cam is rotatably mounted in the housing between the first plurality of tubes and the second plurality of tubes and transverse the direction of flow of all of the tubes. The cam is proportioned to normally compress all of the first and second plurality of tubes and is rotatable to positions whereby either the first or the second plurality of tubes is released from compression to allow flow therein. In a preferred embodiment of the invention there is further provided an elongated flexible sleeve surrounding the cam and forming a friction tube as between the cam and the first and second pluralities of flexible tubes.
