    • The fluid-actuated percussion mechanism includes a housing with an internalylindrical space wherein a reciprocating piston, which divides the space into a working stroke chamber and an idle stroke chamber, is received. The mechanism further includes fluid distributing means and a distribution unit mounted in the housing for placing the chambers and a source of the working fluid in communication. The housing also accommodates a work-performing member adapted to receive impacts from the piston. The distribution unit includes at the inlet of at least one of the chambers a valve made in the form of a resilient annular element. The surface of the distribution unit has valve seats made in it, the number of which corresponds to that of the inlets for supplying the working fluid into the chambers. The resilient valve element is taut about the surface of the distribution unit in opposition to the inlets and encircles the periphery of the unit. The internal surface of the resilient element with the valve seat and the external surface of the resilient element with the housing each define at least one inlet passage for supplying the working fluid to the inlets.The disclosed structure of the valve, of the distribution unit and of the housing enables an increase in the total flow area of the passages through which the working fluid is supplied to the inlets of the chambers and thus an increase in the power output of the percussion mechanism.
    • 流体致动的冲击机构包括具有内部圆柱形空间的壳体,其中容纳将空间分成工作行程室和空转行程室的往复活塞。 该机构还包括流体分配装置和安装在壳体中的分配单元,用于放置室和工作流体源连通。 壳体还容纳适于接收活塞冲击的工作执行构件。 分配单元在至少一个室的入口处包括以弹性环形元件形式制成的阀。 分配单元的表面具有在其中制成的阀座,其数量对应于用于将工作流体供应到室中的入口的数量。 弹性阀元件与分配单元的表面相对于入口张紧并且环绕单元的周边。 具有阀座的弹性元件的内表面和具有壳体的弹性元件的外表面限定了用于将工作流体供应到入口的至少一个入口通道。 所公开的阀门,分配单元和壳体的结构使得能够增加通道的总流动面积,通过该通道将工作流体供应到室的入口,从而增加了冲击的功率输出 机制。

    • The invention relates to the field of water purification. A method for sening water by way of its electrochemical treatment involves causing water to pass in the form of two streams through anode and cathode chambers of a membrane electrolyzer. According to the invention, the water stream being fed to the anode chamber is preliminarily softened before supplying it to the anode chamber, and this stream is in the form of catholyte after the separation of precipitating hardness salts therefrom, anolyte being used as the end product. An electrolyzer for softening water has a casing divided by membranes into anode and cathode chambers, respectively. According to the invention, anodes are spaced from the membrane, and perforation holes of a cathode are in the form of slits extending about perpendicularly with respect to the water flow direction, and projections are provided on the surface of the cathode facing towards the interior of the cathode chamber inbetween the slits, the leading faces of the projections in the flow direction being inclined at an agle of 20.degree. to 40.degree. with respect to the surface of the membranes.The invention may be used in any fields where water softening is required.
