Abstract: The invention discloses a running water powered automatic water recoverer, which mainly comprises a reversing valve and two cylinder type piston cylinders. The two piston cylinders are connected, wherein one piston cylinder is used as a power source cylinder, and the other piston cylinder is used as a water collection cylinder. A water inlet and a water outlet at two ends of the power cylinder are connected to the reversing valve by a water pipe; a power piston reverses the direction of the reversing valve; the reversing valve reverses the running water; and the running water pressure makes the power piston obtain reciprocating mechanical force. Because a piston handle of the collection cylinder is connected with a piston handle of the power cylinder, two pistons reciprocate inside the piston cylinders synchronously. A valve which is used for controlling the inlet and outlet of the water and is provided with a stopping ball is connected to water ports at two ends of the collection cylinder respectively, and is used for controlling the flow direction of water in the collection cylinder; a water inlet and a water outlet are formed on each stopping ball valve; the water inlets of the two valves are connected, the water outlets of the two valves are connected and then a water inlet and a water outlet are formed respectively; and the water inlet is formed in the water to be collected, and the water outlet is connected to a collection tank. When the running water is used, the two pistons automatically work; the piston in the collection cylinder sucks the water to be collected to one side of the collection cylinder; the water on the other side is pressed into the collection tank to be reused; and the collection tank can be placed in a high place. Therefore, the utilization range and collection amount of the collected water are increased, and the water resource and other energy sources are saved.

TL;DR: In this article, a household kitchen garbage cutting and compacting device consisting of a base, a compacting container arranged on the base, left and right water pressure plunger cylinders arranged on two sides of the compact container and a single-acting water pressure cylinder arranged above the compacting containers is described.
Abstract: The invention discloses a household kitchen garbage cutting and compacting device and method. The household kitchen garbage cutting and compacting device comprises a base, a compacting container arranged on the base, left and right water pressure plunger cylinders arranged on the two sides of the compacting container and a single-acting water pressure cylinder arranged above the compacting container. A water pressing plate is arranged in the single-acting water pressure cylinder, a pressing rod is arranged at the lower end of the water pressing plate, and under the effect of water pressure in the single-acting water pressure cylinder, the water pressing plate drives the pressing rod to move vertically. A cutting and pressing block used for pressing kitchen garbage into the compacting container is arranged at the end of the pressing rod. Under the telescopic motion of piston rods of the left and right water pressure plunger cylinders of the compacting container, the compacting container reciprocates between the initial position and the left water pressure plunger cylinder. Based on the principle of transmitting pressure just through household tap water, cutting, compacting, falling and other motions are completed; and no other power source is needed, and therefore the household kitchen garbage cutting and compacting device is simple and practical.

TL;DR: In this paper, the reverse osmosis purification of water or other fluid in a module (10) containing a membrane (11), the water is forced into the module underpressure using two or more piston-cylinder assemblies (25, 26) mechanically interconnected with the pressurised fluid from the module applied to the rear face of the piston (27 or 28) which, from its front face, is driving water into a module, a low pressure continuously operating pump (20) providing a lowpressure on the other piston to supply the necessary extra pressure.
Abstract: In apparatus for the reverse osmosis purification of water or other fluid in a module (10) containing a membrane (11), the water is forced into the module (10) underpressure using two or more piston-cylinder assemblies (25, 26) mechanically interconnected with the pressurised fluid from the module applied to the rear face of the piston (27 or 28) which, from its front face, is driving water into the module, a low pressure continuously operating pump (20) providing a low pressure on the other piston to supply the necessary extra pressure. Valve means (30, 31, 33, 34) automatically reverse the functions of the two cylinders at each end of each stroke. This arrangement obviates any need for a mechanical drive to the pistons of the piston-cylinder assemblies (25, 26).
