摘要： A conduit seat for an atomizing device. The conduit seat is characterized in that one end face of the conduit seat has an water-in and water-out hole corresponding to that of a pump body, and one end face is provided with low pressure water-in tube and high pressure water-out tube, and the center top of the conduit seat has a hole connecting water-in and water-out tube and a separation board is sued to hold the valve seat such that the valve open is a through opening communication from the upper section to the lower section so as to allow the pressure stabilizing structure to seal the valve opening, the bottom section of the water-in tube is a through hole which is connected to the water-in passage of the pump body, and one side of the hole of the pressure stabilizing structure has a water-in hole which is connected to the water-out passage of the pump body such that the pressurized water stream enters the bottom section of the pressure stabilizing structure and deliver via the water-out tube for the atomizing device and when atomizing operation is stopped or interrupted, high pressure water will flow to a buffer space at the bottom section of the pressure stabilizing structure, and the excessive pressure will push the sliding shaft to open the through hole connected to the bottom end of the valve opening, such that the excessive pressurized water is back flown to the water-in side to release pressure.
摘要翻译：用于雾化装置的导管座。导管座的特征在于，导管座的一个端面具有与泵体相对应的入水孔和出水孔，一端面设有低压入水管和高压水 - 导管座的中心顶部具有连接入水管和出水管的孔，并且分离板被起诉以保持阀座，使得阀打开是从上部到下部的通孔连通下部，以使压力稳定结构密封阀开口，该入水管的底部是与泵体的入水通道连接的通孔，并且孔的一侧压力稳定结构具有连接到泵体的出水通道的入水孔，使得加压水流进入压力稳定结构的底部并经由雾化装置的出水管输送并且 n雾化操作停止或中断，高压水将流到压力稳定结构底部的缓冲空间，过大的压力将推动滑动轴打开连接到阀门开口底端的通孔使得过量的加压水回流到水入侧以释放压力。

摘要： A motor pump for high-pressure washers having a structure of the type that comprises a rotating plate that is inclined with respect to its axis and on which at least two pistons push, the pistons being arranged parallel to the axis in radially spaced positions. The rotating plate is associated for joint rotation with a motorized support, which is arranged opposite the pistons and on which the plate can oscillate freely in order to vary its inclination, with respect to the rotation axis, between preset values that determine the axial movement of the pistons, elastic elements for contrasting the variations in inclination induced by the pistons being functionally interposed between the plate and the support.

摘要： A pump includes a pump housing, a rotating shaft extending through the pump housing, a plurality of pistons, and a plurality of control sleeves. Each piston may be at least partially, slidably contained within a respective piston sleeve. The pistons may also be be operably coupled to the rotating shaft such that rotation of the shaft rotates and reciprocates the pistons. Each control sleeve may be slidably disposed on a respective one of said piston sleeves and operable to selectively vary the amount of fluid delivered by the pump.
