PNEUMATIC TIMING UNIT Russian patent published in 2009 - IPC F15B21/02 F15B15/28 F15B11/12 

FIELD: machine building.

SUBSTANCE: unit consists of cylinder, of piston with rod installed in cylinder with forming piston and of rod cavities each having supplying channel. Also apertures are made in the cylinder along its generatrix; the rod cavity is conjugated with the input of a corresponding jet discrete mono-stable element "negative-OR" via each of apertures. The second input of each element "negative-OR" is connected with a timing unit; while the output of each element "negative-OR" is connected with corresponding input of the jet discrete mono-stable multi-input element "OR". The output of the element "OR" is tied with switching input of the trigger with separate inputs; the output of the trigger with separate inputs on which the signal of the unit level is set at entry of the signal of the unit level from the output of the element "OR" is connected with the supplying channel of the rod cavity, while the second output of the trigger with separate inputs is connected with the supplying channel of the piston cavity.

EFFECT: simplification of design, upgraded reliability, expanded functions.
