ABSTRACT:
Apparatus and methods to facilitate alteration of the torque and speed characteristics of a pneumatic motor to reduce start-up reaction torque and minimize run-on time after disconnection of the motor from a source of pressurized gas. A series connected accumulator and proportional gas flow/control/dump valve are inserted between a pressurized gas supply and a pneumatic motor, after which the accumulator volume is optimized by an iterative method to satisfactorily reduce transient motor start-up reaction torque while maintaining motor run-on time within an acceptable range.
