PNEUMOPULSE GENERATOR Russian patent published in 2003 - IPC

FIELD: pneumopulse engineering, applicable in various branches of the national economy for pulse ejection of gaseous, liquid, free- flowing and solid substances. SUBSTANCE: the pneumopulse generator has a barrel built in the body, gating diaphragm attached to the body and positioned before the inlet of the barrel with formation of the control and accumulating cavities, body cover with a dump valve, shut-off piston positioned in the dump valve, spring-loaded to the seat, feed pipe-line and a device for filling the accumulating cavity with compressed air. The claimed generator is featured by the fact that the feed pipe-line is cut in the underpiston section of the dump valve, the seat is fastened in the above-piston section of the dump valve and represents a disk with a discharge opening through which the rod of the shut-off piston passes, the shut-off piston is provided with a drive for its movement and made for closing the feed pipe-line, and discharge ducts are made in its circumference. EFFECT: enhanced energy of the shock wave at a reduced discharge of compressed air and expanded process potentialities of the generator at manual operation. 5 cl, 3 dwg
