Abstract: An energy recovery device comprises at least one cylinder 15, a piston 26 slidable in the cylinder, first valve means 10 for selectively connecting one end of the cylinder to waste liquid at a first relatively high pressure and to drain and second valve means 31, 32 for allowing feed liquid to enter the other end of the cylinder at a second lower pressure via a feed liquid entry port and to be discharged via a feed liquid discharge port from said other end of the cylinder in response to movement of the piston caused by waste liquid entering said one end of the cylinder. Also, means, such as a rod 27 which extends from the other end of the cylinder and into but not through the piston, ensures that the area of the piston acting on the feed liquid is less than the area of the piston acted upon by the waste liquid so that the piston acts as a pressure intensifier to discharge feed liquid through the feed liquid discharge port at a higher pressure than the pressure of waste liquid entering said one end of the cylinder.
Abstract translation: 能量回收装置包括至少一个气缸15，可在气缸中滑动的活塞26，用于选择性地将气缸的一端以第一相对较高压力连接到废液的第一阀装置10和第二阀装置31,32 用于允许进料液体经由进料液入口在第二较低压力下进入气缸的另一端，并且响应于由废物引起的活塞的移动而经由进料液体排出口从气缸的另一端排出 液体进入气缸的一端。 此外，诸如从气缸的另一端延伸而不通过活塞的杆27的装置确保作用在进料液体上的活塞的面积小于由活塞作用的活塞的面积 使得活塞作为增压器，以比进入气缸一端的废液压力更高的压力将进料液体通过进料液体排出口排出。

Abstract: A high pressure water control device comprising a water inlet 10, a high pressure water outlet 12, a low pressure water outlet 13 and a valve 19 for selectively communicating the inlet with one or other of the outlets. The valve is a spool valve comprising a sleeve 20 and a spool 27 slidable in the sleeve. The spool has two axially spaced apart annular seals 28, 29 and the sleeve includes an annular groove 25 in its outer surface and one or more dump ports 26 which communicate between the groove and the inside of the sleeve so that when the dump ports are disposed between the spaced apart seals of the spool high pressure water will be delivered to the high pressure water outlet. The control device may be in the form of a water gun also having an elongate nozzle 11 terminating in the high pressure outlet and a barrel 14 surrounding the nozzle and terminating in the low pressure outlet.
