Cam driven fluid valve assembly

A valve assembly comprising:

• an assembly housing having ports, each port configured to permit fluid communication between an environment of the assembly housing and an interior space of the assembly housing;
• a cam shaft supported on the assembly housing, the cam shaft extending into the interior space and configured to rotate about a rotational axis;
• cams that are disposed in the interior space and supported on the cam shaft, each cam configured to rotate in concert with the cam shaft, each cam comprises a first cam disc fixed to a second cam disc, each cam having an internal groove that is defined between surfaces of the first cam disc and the second cam disc and defines a cam track, the cam track at least partially encircling the rotational axis;
• and
• valves, each valve associated with a respective one of the cams, each valve including
• a valve seat having a valve seat through-opening, the valve seat being disposed in the assembly housing and fixed relative to the assembly housing so as to face a first one of the ports, and
• a valve body that is movable relative to the valve seat, the valve body being disposed in the assembly housing and movable with the assembly housing between a first position in which fluid is permitted to flow through the valve seat through opening, and a second position in which fluid is prevented from flowing through the valve seat through opening,
• wherein
• the valve body is mechanically connected to the cam track of the respective one of the cams, the valve body being moveable relative to the valve seat upon rotation of the cam about the cam shaft.
