PNEUMATIC PULSE GENERATOR Russian patent published in 2007 - IPC F15C1/22 F15B21/12 

FIELD: automatic control pneumatic systems.

SUBSTANCE: proposed generator contains jet flip-flop with separate inputs in each feedback channel of which interrestrictor chamber is installed. Jet analog element with adjusting restrictor and jet discrete element are installed in each feedback channel, one of inputs of each analog element being connected with output of corresponding interrestrictor chamber, second input of each jet analog element being connected with output of corresponding adjusting restrictor. Output of each jet analog element pressure on which rises at increase of pressure at input connected to output of interrestrictor chamber is connected with change-over input of corresponding jet discrete element. Second output of each jet analog element is connected with inhibit input of corresponding jet discrete element, and direct output of each discrete element is connected with corresponding input channel of flip-flop with separate inputs.

EFFECT: improved accuracy and stability in operation, facilitated adjusting.
