Abstract
An impeller for a supercharger is described. The impeller comprises a body having a base and an air intake end wherein the body is adapted to mount to a drive assembly of the supercharger. Further, the drive assembly is able to drive and rotate the body. Precision made air vanes are attached to the body wherein the precision made air vanes and the body are able to be positioned within a volute chamber housing creating precision sealing gaps.
Claims19
A new impeller for a supercharger comprising:
- a body having a base and an air intake end wherein the body is adapted to mount to a drive assembly of the supercharger and the drive assembly is able to drive and rotate the body, and
- precision made air vanes attached to the body wherein the precision made air vanes each extends from the base to the air intake end and wherein the precision made air vanes and the body are able to be positioned within a volute chamber housing and wherein the precision made air vanes have air sealing surfaces that are precisely spaced relative to an inner area of the volute chamber of the supercharger and wherein each of the precision made air vanes further comprises at least one groove that is located substantially parallel to each of the sealing surfaces.
An improved supercharger comprising:
- a new impeller having a body with a base and an air intake end and further having precision made air vanes attached to the body wherein the precision made air vanes each extend from the base to the air intake end and wherein the precision made air vanes have air sealing surfaces and wherein each of the precision made air vanes of the new impeller further comprises at least one groove located along each of the air sealing surfaces,
- a volute chamber housing having a precision made inner area wherein the precision made air vanes and the body are positioned within the volute chamber housing and wherein the air sealing surface of the precision made air vanes are precisely spaced relative to the precision made inner area,
- a drive assembly coupled to the new impeller for driving and rotating the new impeller, and
- a drive assembly mount to which the drive assembly is coupled.
The improved supercharger according to clam 11 further comprising:
- at least one drive source bearing assembly coupled to the hollow drive source shaft and fitted to the drive assembly mount, and
- at least one impeller bearing assembly coupled to the hollow impeller shaft and fitted to the drive assembly mount.
A method of making an improved supercharger comprising the steps of:
- providing a new impeller having a body with a base and an air intake end and further having precision made air vanes attached to the body wherein the precision made air vanes each extends from the base to the air intake end and wherein the precision made air vanes have air sealing surfaces,
- locating at least one groove substantially parallel to each of the air sealing surfaces,
- positioning the new impeller in a volute chamber housing,
- precisely spacing the air sealing surfaces of the precision made air vanes relative to the precision made inner area,
- coupling a drive assembly to the new impeller for driving and rotating the new impeller,
- and coupling the drive assembly to a drive assembly mount.
