초록

A rotary-acting valve is disclosed. In some embodiments, the rotary-acting valve is the pilot or first stage of a two-stage control valve and can be used to create an improved propulsion system for a missile. In the illustrative embodiment, the rotary-acting pilot valve comprises a movable rotor that resides in a chamber. The chamber includes three ports: a gas inlet port, a control volume port that couples to the second stage of a two-stage valve, and a gas vent port. The rotor in the pilot valve selectively pneumatically couples the second stage to eit...
