A rotary disc valve is disclosed which generally includes a housing having an inlet side and an outlet side, and a disc rotatably mounted within the housing between the inlet side and the outlet side thereof. The disc includes an outlet bore which is generally aligned with the axis of rotation of the disc and extends from the outlet face of the disc partially through the disc. One or more inlet bores spaced radially outwardly from the axis of rotation of the disc extend from the inlet face of the disc partially through the disc and communicate with the outlet bore. The inlet bore or bores are located such that a bore may be selectively brought into communication with a single one of inlet side passages by rotating the disc until the bore is aligned with the desired passage. Since the outlet bore and an outlet passage are aligned along the center of rotation of the disc, the outlet bore stays in constant communication with the outlet passage in the outlet side of the housing as the disc is rotated. Therefore, by rotating the disc until an inlet passage is aligned with a respective disc inlet bore, that inlet passage is brought into communication with the outlet passage, making it possible for a fluid to flow through the valve between the inlet and outlet sides.

1. A valve comprising:a) a housing having a first side and a second side; b) a disc mounted within said housing between said first side and said second side thereof and rotatable about a disc central axis, said disc including: i) a disc first face adjacent said housing first side; ii) a disc second face opposite said disc first face and adjacent said housing second side; iii) a first disc bore spaced radially outwardly from said disc central axis, said first disc bore extending from said disc first face partially through said disc; and iv) a second disc bore centered along said disc central axis and extending from said disc second face partially through said disc, said second disc bore having sufficient diameter and depth that said second disc bore communicates with said first disc bore; c) a plurality of first housing passages passing through said housing first side, said first housing passages being spaced radially outwardly from said disc central axis, at least one of said first housing passages selectively communicating with said first disc bore as said disc is rotated about said disc central axis; and d) a housing second passage passing through said housing second side, said housing second passage being generally in alignment with said disc central axis such that said housing second passage stays in constant communication with said second disc bore as said disc is rotated about said disc central axis.
