Beschreibung
Zusammenfassung:	FIELD: mining industry. ^ SUBSTANCE: device has body, striker with central through channel, separating body hollow on chambers of straight and backward drive, air-distributing system, containing stepped feed-discharge valve, valve saddle with apertures for feeding straight action chamber, central pipe, apertures in the body, connected to behind-valve hollow, connected to slit channel. Air-distribution system additionally has discharge channel, positioned between valve saddle and end of greater step of feed-discharge valve, connected on one side to straight action chamber through valve saddle apertures, and on the other side - to slit channel through ring-shaped channel, formed between body and outer surface of greater step of feed-discharge valve. ^ EFFECT: higher efficiency, broader functional capabilities. ^ 2 cl, 2 dwg
