Abstract
Embodiments of the invention provide a supercharger including a housing with a scroll-like upper housing at one end and a gear housing at an opposite end, and an output aperture defined by the upper housing. Some embodiments include a supercharger that has a compression chamber that is at least partially surrounded by at least a portion of the upper housing. The supercharger includes an impeller at least partially positioned in the compression chamber, and a variable or interchangeable inlet extending from the housing that defines an inlet aperture fluidly coupled to the compression chamber. Some embodiments include an anti-backlash gear assembly coupled to an impeller gear of the impeller.
Claims20
A supercharger comprising;
- a housing including a scroll-shape upper housing at one end and a gear housing at an opposite end;
- an output aperture defined by the upper housing;
- a compression chamber at least partially surrounded by at least a portion of the upper housing;
- an impeller at least partially positioned in the compression chamber, the impeller coupled to or integral with an impeller shaft;
- and
- an interchangeable inlet extending from the housing, the inlet defining an inlet aperture fluidly coupled to the compression chamber;
- and
- an anti-backlash gear coupled to an input gear for coaxial rotation therewith, whereby portions of both the anti-backlash gear and the input gear are configured and arranged to simultaneously engage an impeller gear coupled to or integral with the impeller shaft to reduce backlash.
A supercharger comprising;
- a housing including an output aperture;
- a compression chamber at least partially surrounded by at least a portion of the housing;
- an impeller at least partially positioned in the compression chamber, the impeller coupled to or comprising an impeller shaft including an impeller gear;
- an anti-backlash gear coupled for coaxial rotation with an input gear, the input gear including springs positioned in recesses;
- and
- an interchangeable inlet constrictor defining an inlet aperture, the inlet aperture fluidly coupled to the compression chamber.
A supercharger assembly comprising;
- a housing including an output aperture;
- a compression chamber at least partially surrounded by at least a portion of the housing;
- an impeller at least partially positioned in the compression chamber, the impeller coupled to or including an impeller shaft including a coupled or integrated impeller gear;
- an inlet aperture defined by an interchangeable inlet constrictor coupled to an inlet wall of the inlet aperture, the inlet constrictor comprising an inner diameter defining an inlet region at one end and an outlet diameter at an opposite end, wherein the inlet constrictor is configured to be swapped with another inlet constrictor comprising a different inner diameter;
- an anti-backlash gear coupled with an input gear, the input gear including springs positioned in recesses;
- and
- at least one oil guide proximate the impeller gear.
