Claims
- 1. A pneumatic multiplexer comprising:
- a stator including a stator face and a plurality of input ports;
- a rotor including a first rotor face, a reverse rotor face and a rotor channel extending therebetween;
- a rotor housing fixedly connected to said stator and enclosing said rotor;
- a central tube situated in said rotor housing and being in flow communication with said rotor channel;
- means for driving said rotor at a continuious angular velocity relative to said stator; and
- a plurality of arc grooves in said stator face each being in flow communication with one of said input ports and each sequentially being in flow communication with said rotor channel.
- 2. A pneumatic multiplexer according to claim 1, further including:
- a relief groove.
- 3. A pneumatic multiplexer according to claim 2, wherein said rotor includes an o-ring in said reverse face adapted to maintain contact with a dynamic seal on said rotor housing.
- 4. A pneumatic multiplexer according to claim 3, wherein:
- said rotor housing further includes pressure equalization passages and an overboard drain; and
- means for detecting the angular position of said rotor with respect to said stator.
- 5. A pneumatic multiplexer according to claim 4, wherein said detecting means comprises: at least one hole drilled in said rotor; and a speed pickup.
