AI Technical Summary

Benefits of technology

The present invention is about a new kind of vane pump assembly. It has a more efficient and cost-effective design compared to other vane pump assemblies. It includes a housing with an inner wall and an open chamber where a rotor is placed. The rotor has a circular shape and has two vanes that move in opposite directions. A bell crank connects the two vanes and allows them to move together as the rotor rotates. This design ensures that both vanes are always in contact with the inner wall of the housing, which improves efficiency and performance.

Problems solved by technology

However, it is often costly as expensive and time consuming manufacturing and / or machining processes must be employed to achieve such tight tolerances.

Embodiment Construction

[0032]Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a first exemplary embodiment of an improved vane pump assembly 20 is generally shown in FIGS. 1-4. The vane pump assembly 20 includes a housing 22 with an inner wall 24 which defines an open chamber that is generally elliptical, or oval, in shape when viewed in cross-section. The exemplary housing 22 has a total of four ports 26, 28 with two of them being fluid inlet ports 26 for conveying a fluid, such as steam, into the open chamber and two of them being fluid outlet ports 28 for dispensing the fluid out of the open chamber. Although two of each are shown in the exemplary embodiment, it should be appreciated that the housing 22 could be configured with any suitable number of inlet and outlet ports 26, 28.

[0033]The vane pump assembly 20 further includes a rotor 30 which is generally circular in shape and is centered within the elliptical open chamber of the housing 22. T...

Abstract

The vane pump assembly includes a housing with an inner wall that surrounds an open chamber. A rotor is rotatably disposed in the open chamber and has a circular shape when viewed in cross section. A first pair of vanes are received in the rotor and are operably connected with one another by a first bell crank which is pivotable about a pivot axis such that movement of one vane inwardly into the rotor causes the other vane to move outwardly out of the rotor to maintain both vanes in contact with the inner wall as the rotor rotates relative to the housing during operation of the vane pump assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit and priority to U.S. Provisional Patent Application No. 62 / 311,003 filed Mar. 21, 2016, the entire disclosure being considered part of the disclosure of this application and hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is related, generally, to pneumatic and hydraulic pumps, motors and heat regenerative systems.[0004]2. Related Art[0005]In general, rotary vane pump assemblies are positive displacement pumps that include one or more vanes that are mounted to a rotor which is rotatable within a housing having an inner wall defining an open chamber. A pressure differential is applied across the vane, which causes the rotor to rotate within the open chamber of the housing. The rotor is coupled with an output shaft which may be attached to any suitable machine including, for example, an electric generator. During operation of such vane ...
