Abstract
Exemplary embodiments are directed to rotary shear valves which include a stator, a rotor defining a cavity extending at least partially therethrough, and a bladder. The rotor is rotatably mounted relative to the stator to create at least one fluidic path therebetween. The bladder comprises a polymer disposed inside the cavity. Exemplary embodiments are also directed to methods of operating a rotary shear valve.
Claims28
A rotary shear valve, comprising:
- a stator;
- a rotor defining a cavity extending at least partially therethrough and rotatably mounted relative to the stator to create at least one fluidic path therebetween;
- and
- a bladder comprising a polymer disposed inside the cavity.

A method of operating a rotary shear valve, comprising:
- providing a stator,
- providing a rotor defining a cavity extending at least partially therethrough and rotatably mounted relative to the stator to create at least one fluidic path therebetween,
- positioning a bladder comprising a polymer inside the cavity of the rotor, and
- transmitting a compressive stress into the bladder,
- wherein transmitting the compressive stress into the bladder distributes contact stresses between the rotor and the stator.
