Embodiment Construction

[0029] It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions, directions or other physical characteristics relating to the embodiments disclosed are not to be considered as limiting, unless the claims expressly state otherwise.

[0030] Referring now to FIGS. 1-3 of the present invention, a rotor portion 20 comprising a shaft 22 and at least two rotor blades 24 located on the shaft 22, is depicted as exploded from a stator housing portion 26. The rotor blades 24 may be integrally formed with the shaft 22 or they may be separate pieces that are secured to the shaft 22. Preferably, at least the rotor blades 24 are construc...

Abstract

A device for changing the pressure of a fluid having a shaft with rotor blades spiraling in a first direction located on the shaft. The rotor blades rotate adjacent stator vanes that spiral along a stator housing in a direction opposite the first direction. The device changes the pressure of a fluid from a pressure P1 to a pressure P2.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a device, such as a compressor or vacuum pump, for changing the pressure of a fluid, such as water or air. BACKGROUND OF THE INVENTION [0002] Generally speaking, devices, such as compressors or vacuum pumps, that change the pressure of a fluid, such as water or air, are well known to those skilled in the art. Such pressure changing devices can be found in a wide variety of applications including, but not limited to, jet watercraft, such as jet-skis®, turbo charges for vehicles, such as automobiles, jet engines and blowers for inflatable devices. [0003] It is also well known that pressure changing devices take many different forms. One form of a pressure changing device is commonly known as an axial flow device since the fluid it moves travels generally parallel with respect to an axis of rotation of the device. Typically, in an axial flow device, a rotor is located within and parallel to a stator, to move fluid through t...
