FIELD: power engineering.
SUBSTANCE: proposed device contains service tank with two valves. Upper valve of service tank is normally open, and lower one is normally closed. Tubular shanks are connected coaxially and hermetically to lower surfaces of each valve. Each shank is installed for vertical shifting onto corresponding outlet end of pipe for impulse delivery of gas. Hydraulic restrictor is installed at outlet end of pipe for impulse delivery of gas.
EFFECT: increased distance of transportation of powder-like material.
