Abstract
A rotary shear valve having a rotor device and a stator device both with planar faces. The stator face includes a central port located at a common rotational axis, a second port radially spaced a radius R1 from the central port, and a third port spaced at radius R2. The second and third ports are in general linear alignment with the central port. The rotor face includes a first rotor groove extending radially outward from the common rotational axis to a position at radius R2 from the central port. The rotor device is rotatably mounted to the stator device for rotation thereof about the axis, providing fluid-tight, selective relative rotation therebetween between two or more discrete rotor positions. When in a discrete first rotor position, the first rotor groove is oriented in radial alignment with, and fluidly connects, the central port and the second port with the third port.
