  • Pneumatic actuator system and method
    Patent number: 4075930
    Abstract: A system for precisely positioning a linearly movable output member incorporates an improved nonexpansion, bi-directional vane motor whose internal gas carrying chamber is configured to prevent radial vane reciprocation while the vanes of the motor are under pressure-generated side load. Position of the output member is electrically sensed and in response to the sensed position, pressurized gas flow to the vane motor is adjusted to precisely position the output member.
