Abstract

An apparatus and a method are provided for an air filter configured to be mounted onto air inlets of turbochargers and superchargers. The air filter a proximal base including an inlet receiver configured to receive an air inlet, a clamp to secure the air inlet within the inlet receiver, and a first opening aligned with a screw mechanism of the clamp. A filter medium fastened to the proximal base is configured to remove particulate matter and other contaminates from an incoming air stream. A distal end cap fastened to the filter medium comprises a second opening aligned with the first opening. A conduit within an interior cavity of the air filter is disposed between the first opening and the second opening, facilitating tightening and loosening the clamp by extending an appropriate tool through the interior cavity so as to engage the screw mechanism of the clamp.

First claim

What is claimed is:

1. An air filter for turbochargers and superchargers, comprising:
a base for supporting a filter medium wherein base includes a ridge and a recess configured to fixedly receive an end of the filter medium;
an end cap for enclosing an interior cavity of the filter medium; and

a conduit disposed between a first opening in the base and a second opening in the end cap.

2. The air filter of claim 1 , wherein the first opening and the second opening are configured to facilitate extending a tool through the conduit to engage a screw mechanism comprising a clamp for securing the air filter to an air inlet comprising the turbocharger or supercharger.

3. The air filter of claim 2 , wherein the clamp comprises a metal band disposed around an inlet receiver comprising the base.

4. The air filter of claim 2 , wherein the screw mechanism is configured to enable tightening and loosening the metal band.

5. The air filter of claim 1 , wherein the base is configured to provide an interface between the air filter and an air inlet comprising the turbocharger or supercharger.

6. The air filter of claim 5 , wherein the base includes an inlet receiver for receiving the air inlet and a clamp for securing the air inlet within the inlet receiver.

7. The air filter of claim 1 , wherein the conduit is disposed within the interior cavity of the filter medium.

8. The air filter of claim 7 , wherein the conduit is configured to guide a tool through the interior cavity to a screw mechanism comprising a clamp for securing the air filter to an air inlet comprising the turbocharger or supercharger.

9. The air filter of claim 7 , wherein the conduit prevents unfiltered air from entering the interior cavity through one or more of the first opening and the second opening.

10. The air filter of claim 1 , wherein the ridge is configured to be crimped onto the filter medium and an accompanying wire support.

11. The air filter of claim 10 , wherein the ridge is configured to be molded onto the filter medium and the wire support.

12. A method for an air filter for turbochargers and superchargers, comprising:
configuring a base for supporting a filter medium wherein configuring the base includes configuring a ridge and a recess to fixedly receive an end of the filter medium;
forming an end cap for enclosing an interior cavity of the filter medium; and
disposing a conduit between a first opening in the base and a second opening in the end cap.

13. The method of claim 12 , wherein configuring the ridge and the recess includes crimping the ridge onto the filter medium and an accompanying wire support.

14. The method of claim 12 , wherein configuring the ridge and the recess includes molding the ridge onto the filter medium and an accompanying wire support.

15. The method of claim 12 , wherein configuring the base includes forming an inlet receiver to receive an air inlet comprising the turbocharger or supercharger.

16. The method of claim 12 , wherein configuring the base includes forming the first opening; and wherein forming the end cap includes forming the second opening.

17. The method of claim 12 , wherein disposing the conduit includes extending the conduit across the interior cavity.

18. The method of claim 12 , wherein disposing the conduit includes aligning the conduit with a screw mechanism comprising a clamp for securing the base to an air inlet comprising the turbocharger or supercharger.
