摘要： A liquid accumulator comprises a generally cylindrical receptacle (10) having a flexible membrane (14) dividing the interior of the receptacle into a liquid chamber (15) and a gas chamber (17). The membrane comprises a hose which is open at both ends, one of which is bent inwards and conveyed through the hose and the ends of the hose are interconnected to form outer and inner membrane walls between which said liquid chamber is enclosed.

摘要： The invention relates to a pump arrangement, especially for the operation of an osmotic water purifier comprising a filter housing (10) having a raw water inlet (11), a filtrate outlet (15), a reject outlet (16), and a flush valve (18) adapted to be opened for flushing raw water through the filter housing. The pump arrangement comprises a high pressure pump (12) for supplying raw water at the required pressure, and a circulation pump (13) for recirculating a relatively large flow through the filter housing. The high pressure pump (12) consists of a sliding vane pump of the type in which the vanes (24) are caused to sealingly engage the surrounding wall of the pump chamber by a hycraulic pressure supplied from the pressure side of the high pressure pump. The inlet of the high pressure pump is connected to a pressurized water supply line, whereby, when the flush valve (18) is opened and said pressure ceases, said vanes are moved radially inwards and the high pressure pump is opened for allowing a through flow exceeding its normal capacity.
摘要翻译：本发明涉及一种泵装置，特别是用于渗透水净化器的操作，该渗透水净化器包括具有原水入口（11），滤液出口（15），排出口（16）和冲洗出口适于打开的阀（18）用于冲洗通过过滤器壳体的原水。泵装置包括用于供应所需压力的原水的高压泵（12）和用于使较大流量再循环通过过滤器壳体的循环泵（13）。高压泵（12）包括滑动叶片泵，其中叶片（24）通过从高压泵的压力侧提供的液压压力与泵室的周围壁密封地接合。高压泵的入口连接到加压水供应管线，由此当冲洗阀（18）打开并且所述压力停止时，所述叶片径向向内移动，并且高压泵打开以允许通过流动超过正常容量。

摘要： This invention relates to a variable speed transmission for small high speed motors. The transmission comprises an input and an output shaft (11 and 21) the output shaft (21) being surrounded by two concentric annular plates (15, 16) being supported for rotating motion on the output shaft (21). The plates (15, 16) are in engagement with rolling elements (18) applied in a holder (20) for the elements secured on the output shaft (21) the plates being driven from the input shaft (11) via a drive roller (12) placed between and abutting the two plates.
