Fluid control apparatus

A fluid control apparatus for interconnecting at any one time any two, but not more than two, of a plurality of individual sources of fluid and receptacles for fluid, the fluid control apparatus comprising a housing having a wall enclosing a substantially cylindrical interior substantially concentric to a longitudinal axis and having four housing ports extending through the wall and communicating with the interior of the housing, said housing ports spaced from each other ninety degrees (90.degree.) about the wall relative to said longitudinal axis so that each of said housing ports is in axial alignment with a housing port on the opposite side of the housing through said interior thereof;

• means for individually connecting each of said housing ports to one of the sources of fluid or receptacles for fluid;
• and a valve member mounted in said interior of the housing for movement therewithin substantially about said longitudinal axis and having a substantially cylindrical external surface disposed in facing engagement with said wall of the housing, a first valve port, individually positionable in fluid transferring relation with each of said housing ports, an elongated second valve port, extending approximately ninety degrees (90.degree.) about the periphery of the valve member to opposite ends and disposed on the opposite side of the valve member from said first valve port, and a passage extending through the valve member interconnecting the first valve port and the second valve port and wherein said passage has a "Y" shaped configuration having two portions thereof disposed at a right angle to each other interconnecting the opposite ends of the second valve port whereby said valve member can selectively be positioned in a plurality of fluid transferring positions but in each of said fluid transferring positions can connect only two of said four housing ports at any one time through the passage thereof.
