Abstract

A fluid-driven motor has a manifold with an arcuate seal including first and second valve openings and a sealing surface. A cylinder pivotally mounted on the manifold has a facing surface cooperating with the arcuate seal. The arcuate seal and the facing surface define a position-responsive valve configuration such that, when the cylinder assumes a neutral position, an aperture of the facing surface faces the sealing surface, and when the cylinder is angularly displaced in either direction, the aperture overlaps one or other of the valve openings, thereby connecting to the correspond fluid flow channel in the manifold. A pressure compensation volume underlies the sealing surface and receives fluid pressure from the fluid flow channels through valves, or from the internal volume of the cylinder, so that a pressure within the pressure compensation volume approaches a value no less than a current pressure within the internal volume.

Abstract

The hydroelectric generator of the present invention provides a pre-sealed, watertight device in which the rotor that includes the induction magnets is deployed within the main flow passage of the pipeline and thereby sealed within the pipeline, and he induction coil assembly is deployed outside of the pipeline such that the fluid is sealed within the pipeline away from the induction coils.

Abstract

The self-powered non-contact water outlet appliance of the present invention is configured so as to be deployed at a point of use as a unitary housing that encases a power supply unit and a flow control system. The power supply unit includes a pipeline-deployed electric generator deployed in a fluid flow passage configured in the outlet appliance and a power storage device that is charged by the electric generator. The generator is operatively responsive to a flow of fluid through the fluid flow passage. The flow control system includes an electronically actuated fluid flow control valve configured to control a flow of fluid through the outlet appliance, at least one sensor configured to sense a necessity to actuate the flow control valve, and a management system configured to manage operation of the flow control valve conditional to output received from the at least one sensor. Therefore, the water outlet appliance of the present invention may be connected to substantially any suitable water system supply pipeline at the point of use by performing a single connection action.
