JET DEVICE FOR POSITIONING OF RECIPROCAL MOTION DRIVE Russian patent published in 2009 - IPC G05B19/44 

FIELD: physics, control.

SUBSTANCE: invention is related to technical facilities of automation and may be used in pneumatic systems of automatic control. Jet device for positioning of reciprocal motion drive comprises cylinder with installed piston and stem, which is rigidly fixed to base metering scale, which actuates metering element. Proposed device differs from available ones by the fact that metering element is arranged in the form of pneumatic sensor, pressure value at the outlet of which is proportional to value of metering gap between detector and metering scale arranged in the form of rotary plank, incline of which is set by adjustment screw, at that outlet of pneumatic detector is connected to control inlet of jet threshold device, at the outlet of which control signal is generated, and inlet of jet threshold device displacement is connected to adjustment throttle.

EFFECT: design simplification and expansion of functional resources, since it makes it possible to generate control commands at any required position of piston.
