FIELD: machine building.
SUBSTANCE: method for control of rotation frequency of pneumatic rotary engine consists in throttling outlet orifices of engine depending on rotation frequency. The outlet orifice is connected with a silencer including a chamber connected with an inlet of a pneumatic converter with a rod. The rod transferring a control element of a throttle performs throttling. Degree of throttling is set depending of pressure level occurring in the silencer chamber.
EFFECT: control over rotation frequency with one regulator.
