FLOW CONTROL AND ACTUATOR INCLUDING THIS FLOW CONTROL Russian patent published in 2022 - IPC F15B11/04 F15B13/42 

FIELD: air flow devices.

SUBSTANCE: invention can be used in devices using air flow. The flow regulator (12) is designed to change the flow rate of air supplied or discharged through at least one of the first channel (14) communicating with one port (104) of the air cylinder (100), and the second channel (16) communicating with another port (102) air cylinder, in the middle of the stroke section. The flow regulator (12) contains the first switching valve (20), the first inlet channel (21) and the second control valve (26). The first switching valve (20) is movable from the first position to the second position under the action of pilot air and is designed to ensure communication of one port (104) of the air cylinder (100) with the first channel (14) in its first position and communication of one port (104) of an air cylinder (100) with an air outlet (48a) through the first control valve (28) in its second position. The first inlet (21) is designed to direct pilot air from the second channel (16) to the first switching valve (20). The second control valve (26) installed in the first inlet channel (21) and designed to control the moment of displacement of the first switching valve (20) by controlling the pilot air flow. A drive device (10) containing a regulator (12) is disclosed.

EFFECT: increasing the ease of regulation of the regulator.
