    摘要： The invention relates to an apparatus for dosing a liquid product into water, particularly for dosing a liquid detergent product into the water stream fed to domestic washing machines. The apparatus is driven by the water pressure and therefore consists of two hydraulic pressure chambers into which the water is alternately directed. In these chambers two rigidly connected pistons are moved. The pistons are connected to the housing by membrane seals. On one side of the apparatus a pumping part with a pumping chamber is located, into which one of the pistons can move. The pumping chamber is provided with a non-return valve for unidirectionally controlling the flow of the liquid product from a reservoir and with another non-return valve for unidirectionally feeding the liquid product into the water stream in the common outlet pipe. The pistons are connected to an electrically controlled valve assembly for alternatively directing the water stream to one of the two hydraulic pressure chambers. The aforementioned assembly may comprise a pawl and ratchet operated device for counting, adjusting and limiting the number of strokes for one dosing operation. Different amounts of liquid products can be dosed by predetermining the number of strokes. Differences in the water pressure do not influence the quantities dosed. Water can flow through the apparatus also before and after the dosing operation.

    摘要翻译： 本发明涉及一种用于将液体产品计量给水的设备，特别是用于将液体洗涤剂产品投入到送入家用洗衣机的水流中。 该装置由水压驱动，因此由两个液压室组成，水被交替地引导到其中。 在这些室中，两个刚性连接的活塞被移动。 活塞通过膜密封件连接到外壳。 在设备的一侧，设有具有泵送室的泵送部分，活塞中的一个可以移动到其中。 泵送室设置有用于单向控制来自储存器的液体产物的流动的止回阀和用于将液体产物单向地供给到公共出口管中的水流中的另一单向阀。 活塞连接到电控阀组件，用于将水流交替地引导到两个液压室中的一个。 上述组件可以包括棘爪和棘轮操作的装置，用于计数，调节和限制一次给药操作的冲程次数。 可以通过预先确定笔画的数量来计量不同量的液体产品。 水压差异不影响剂量。 水也可以在配料操作之前和之后流经设备。

    摘要： An electrostatically driven diaphragm micropump comprises a first pump bodys a counterelectrode and a second pump body having a diaphragm region. The two pump bodies establish a hollow space bordering on the diaphragm region and are electrically insulated from each other. The hollow space is filled with a medium different from the fluid to be pumped. The pump bodies may consist of a semiconductor material of different types of charge. The medium in the hollow space preferably has a high dielectric constant.

    摘要： An improved air compressor includes a cylinder fitted with a piston body, a main frame for mounting a motor, and an air storage container. The cylinder defines at its top wall a plurality of exit holes, which are separated by a plurality of blocking walls and regulated by a resilient sheet having a plurality of branches corresponding to the exit holes. When the compressed air produced in the cylinder pushes the resilient sheet up to open the exit holes, the instantaneous high-pressure air that flows through the exit holes can be restrained by the air blocking walls to prevent the air from interfering with movements of the branches of the resilient sheet, so that the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.

    摘要： A valve comprising a base plate defining an inlet and outlet passageway. A cover plate is disposed on the base plate and defines a first and second channel. A pressure plate is disposed on the base plate and includes a first anchoring portion, a first sealing portion, and a first biasing portion connecting the first anchoring portion and the first sealing portion. Furthermore, a suction plate is disposed on the base plate and includes a second anchoring portion, a second sealing portion, and a second biasing portion connecting the second anchoring portion to the second sealing portion. The valve is movable between a first configuration, where the first sealing portion is distal to first channel and the second sealing portion is proximal to inlet passageway, and a second configuration, in which the first sealing portion is proximal to first channel, and second sealing portion is distal to inlet passageway.
