In liquid ring pumps having conical port members, cavitation and associated operating noise are reduced by providing a second subsidiary discharge port beyond the closing edge of the main discharge port in the direction of rotor rotation. |

A liquid ring pump of the duplex, center-port type in which the two rotors are mounted upon a common shaft and disposed between them and common to each section of the pump, is a single header to which the outlet from the pump sections are delivered and from which the intake is drawn.

A liquid ring pump has a conical port member located within the corresponding central opening in the rotor and defines with the rotor a working clearance. Wear on the surfaces defining the working clearance reduces the efficiency of the pump. The present construction offers the ability to readjust the position of the port member so that the original clearance between the port member taper and the rotor can be re-established, and the pump performance increased to its full capacity. This adjustment may be made without the disassembly of the pump.

A method and at least two devices demonstrate improvements to energy extraction from a compressible working fluid in a liquid ring heat engine, which has a rotor mounted in a case. A space in the case is occupied by a liquid that establishes a liquid ring piston for the rotor. The rotor defines at least a first and a second operating zone. In the first zone, the working fluid is expanded against the liquid and, in the second zone, the working fluid is re-compressed. Between the two zones, the working fluid is cooled. In one device, the cooling step occurs on the rotor in a third zone. In another device, the cooling occurs outside of the case. |

Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. In some embodiments of the invention, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, and a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient. |
