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. |

1. A rotary shear valve assembly comprising:
a rotor device having a substantially planar rotor face, and a stator device having a substantially planar stator face, and defining a first passage extending therethrough that terminates at a central port on said stator face, and at a common central rotational axis of both said rotor face and said stator face, said stator device further defining a second passage extending therethrough that terminates at a second port on said stator face, and radially spaced a radius R1 from said central port, and said stator device further defining a third passage extending therethrough that terminates at a third port on said stator face, radially spaced a radius R2 from said central port and in general linear alignment with said central port and said second port, wherein radius R2 is greater than radius R1; said rotor device further having a first rotor groove defined in said rotor face and extending radially outward from said common central rotational axis to a position generally at said radius R2 from said central port, said rotor device being rotatably mounted to said stator device for rotation thereof about said rotational axis in a manner enabling fluid-tight, selective relative rotation between the rotor face and the stator face, at a rotor-stator interface, between two or more discrete rotor positions, wherein when said rotor device is in a discrete first rotor position, said first rotor groove is oriented in radial alignment with, and fluidly connects, said central port and said second port with said third port. |
