A valve assembly includes a first gate having at least one opening and a second gate having at least one opening, the second gate being spaced from the first gate. The valve assembly has first and second discs disposed between the first and second gates, each disc having at least one opening, whereby the discs are coupled together for simultaneously rotating between a valve open and a valve closed position. The assembly also includes a biasing element disposed between the first and second discs for normally urging the discs away from one another and toward opposing inner faces of the first and second gates.

A rocker valve for alternately sealing one of two outlet ports is provided with two cylinders in which there are respectively disposed pistons carrying sealing members for longitudinal reciprocation along the extended axes of valve seats respectively surrounding the port openings. The rocker is rotated to urge one piston toward its respective valve seat while permitting the other piston to be retracted from its respective valve seat. An elastomeric diaphragm is mounted between the sealing members mounted on the pistons and the valve seats whereby the sealing members urge the diaphragm against the valve seats during sealing. The longitudinal motion of the pistons prevents skewing of the sealing members during rotation of the rocker arm for maintaining the sealing members parallel to the valve seats throughout the strokes of the pistons.
