    • The invention relates to a powder supply device (1) for a laser powder welding device and a laser powder welding device having such a powder supply device (1). The powder supply device (1) comprises a nozzle head (3) which tapers along a longitudinal axis (2) of the powder supply device (1) in the direction to a first end (4) and has a cavity (6). The cavity (6) is arranged radially about the longitudinal axis (2) in an interior of the nozzle head (3) and tapers to the first end (4) of the nozzle head (3). The cavity (6) opens out into an annular opening (7) which is arranged at the first end (4) for discharging a powder. The powder supply device (1) has a plurality N of powder feed lines (8-1, 8-2, 8-3) which extend through a second end (5) of the nozzle head (3), which lies opposite the first end (4) of the nozzle head, in the direction to the cavity (6) and are designed to direct the powder from a powder reservoir into the cavity (6).
    • 本发明产生一个粉末进料器(1)用于激光粉末堆焊设备和激光粉末堆焊装置,具有这样的粉末进料器(1)。 粉末进料器(1)具有一个沿纵向轴线(2)的粉末进料器(1)的第一端(4)的变细的喷嘴头(3)用的腔体(6)。 所述(6)的阀腔被布置在所述喷嘴头部的内部(3)径向于所述纵向轴线(2)和朝向所述第一端部逐渐变细(4)的喷嘴头(3)。 所述空腔(6)通入在所述第一端(4),其设置用于排出的粉末环形开口(7)。 粉末进料器(1)具有通过第一端(4)的喷嘴头(3)的相对的第二端(5)的喷嘴头延伸的多个Pulverzuführrohrleitungen的N(8-1,8-2,8-3)(3 )延伸到所述腔体(6),并适于从粉末储存器中的粉末引导到空腔(6)。
