Abstract
A method and device for regulation of the output power of a fluid power motor involving the bypass of a selected portion of the supplied pressure fluid to the motor exhaust as a means of effectively reducing the available pressure drop across the motor and thereby its power output.
Claims10
A power regulator for a pneumatic pressure fluid motor comprising:
- a pneumatic pressure fluid motor means;
- an inlet means for supplying pneumatic pressure fluid to said motor means;
- an exhaust means for exhausting expanded pressure fluid from said motor means to atmosphere;
- and
- adjustable means for bypassing a selected portion of said supplied pressure fluid to said exhaust means as a means for selectively backpressurizing said pneumatic pressure fluid motor as a means for reducing the output power of said pneumatic pressure fluid motor.
