Abstract A powder feeding system for a thermal spray gun provides uniform control of powder feed rate with a minimum of pulsation during operation and without feeding during idle mode. The feeder is comprised of an enclosed hopper for containing a powder to be thermal sprayed, a carrier conduit connected between a carrier gas supply and a thermal spray gun, a feed gas conduit for discharging a regulated supply of feed gas under pressure into the hopper, and one or preferably more powder intake orifices extending from the carrier conduit into the hopper below the normal minimum level of powder. The intake conduits have a geometric design and arrangement such that there is no gravity flow of powder therethrough into a carrier gas stream in the absence of a feed gas flow therethrough. The axes of the intake orifices extend away from the carrier conduit at an acute angle to the axis of the carrier conduit as defined by the direction of carrier gas flow. Preferably there is a constriction in the carrier conduit downstream of the intake orifices.
