    摘要： The present invention relates to a powder feeding device (100), in particular for coating powder. The powder feeding device (100) comprises a dense phase powder pump (1) which has at least one conveying chamber (4) with a powder inlet valve (7) and a powder outlet valve (8). Furthermore, a control device (90) is provided for selectively operating the dense phase powder pump (1) in a powder conveying operating mode or a flushing operating mode. The powder inlet valve (7) and the powder outlet valve (8) of the dense phase powder pump (1) are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. It is provided according to the invention that the control device (90) is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve (7) and/or powder outlet valve (8) preferably automatically and more preferably selectively automatically depending on the respective operating mode of the dense phase powder pump (1) and/or depending on a pressure which prevails in the conveying chamber (4).

    摘要翻译： 粉末供给装置技术领域本发明涉及一种粉末供给装置（100），特别涉及涂料粉末。 粉末供给装置（100）包括密相粉末泵（1），其具有至少一个具有粉末入口阀（7）和粉末出口阀（8）的输送室（4）。 此外，设置有控制装置（90），用于以粉末输送操作模式或冲洗操作模式选择性地操作密相粉泵（1）。 密相粉泵（1）的粉末入口阀（7）和粉末出口阀（8）在每种情况下被构造为气动致动的压缩阀，当施加致动压力时可以关闭该压缩阀。 根据本发明提供的是，控制装置（90）被配置为优选地自动设定用于关闭粉末入口阀（7）和/或粉末出口阀（8）所选择的致动压力的压力值 优选地根据密相粉末泵（1）的相应操作模式和/或根据在输送室（4）中的压力来选择性地自动选择。

    摘要： A powder supplying device for a powder coating installation with at least one closable powder container, which has a substantially cuboidal powder chamber for coating powder and a fluidizing device for introducing fluidizing compressed air into the powder chamber. At least one inlet opening is provided in a side wall of the powder container for feeding coating powder during a powder coating operation of the powder coating installation or for introducing cleaning compressed air during a cleaning operation of the coating installation. At least one outlet is provided for discharging fluidizing compressed air introduced into the powder chamber or for discharging cleaning air introduced into the powder chamber during the cleaning operation together with residual powder transported along with the cleaning compressed air. At least one powder feed line and at least one cleaning compressed-air feed line are connected via a diverter to the at least one inlet opening.
