<p>1. A machine for the recharging of mechanical components using the "plasma" method, of the type comprising a torch (4) and a powder distributor (2), with a rotary disc (22) having a vertical axis (23) and a scraper (27) for the supply of the torch (4), the powder being removed towards the periphery of the disc (22) and flowing from there via a conduit (5, 6) to the torch (4), characterised in that the powder distributor comprises at least one gas injector (31) comprising a receiver in the form of a funnel (33) disposed below the periphery of the rotary disc (22) and rising above a diffusor (32) with a lateral gas inlet (37) and gas intake apertures (38), the shape of the diffusor (32) and the arrangement of the intake apertures (38) being such that a gas eddy is created, into which the powder is sprayed, an outlet (40) disposed at the base of the injector (31) under the diffusor (32) being connected, via the conduit (5, 6), to the torch (4).</p> |
