Abstract
Abstract An air cleaner assembly includes an intake pipe which is provided with a switching valve means adapted to selectively effect through the intake pipe flow of either cool air or warm air. The assembly includes a joint tube, which is secured to the casing of the assembly within which an air cleaning element is housed, with part of the joint tube being in engagement with a part of the intake pipe in a telescopic relationship therewith. A resilient sealing material is sandwiched between a wall of the joint tube and the corresponding wall of the intake tube at the telescopic interconnection therebetween. The casing of the air cleaner assembly and the intake pipe are mounted by means of stays securing these elements to suitable parts of an internal combustion engine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
An air cleaner assembly comprising a casing having an air cleaning element therein, intake pipe means connected to both a source of warm air and a source of cool air, switching valve means carried by said intake pipe means for selectively directing either warm air or cool air through said intake pipe means from said sources of said air, a joint tube secured at one end thereof to said casing and having its other end connected with said intake pipe in telescoping relationship therewith, said joint tube providing communication between said intake pipe means and the interior of said casing for introducing air from said intake pipe into said casing, and a resilient sleeve member carried at said other end of said joint tube positoned interiorly within one of said telescoping members and surrounding the other said telescoping member extending axially along the area of telescoping overlap and being sandwiched in airtight engagement between said joint tube and said intake pipe.
Claim 2
Dependent Claim
161 words
An air cleaner assembly comprising a casing having an air cleaning element therein, intake pipe means connected to both a source of warm air and a source of cool air, switching valve means carried by said intake pipe means for selectively directing either warm air or cool air through said intake pipe means from said sources of said air, a joint tube secured at one end thereof to said casing and having its other end connected with said intake pipe in telescoping relationship therewith, said joint tube providing communication between said intake pipe means and the interior of said casing for introducing air from said intake pipe into said casing, and a resilient sleeve member carried at said other end of said joint tube positoned interiorly within one of said telescoping members and surrounding the other said telescoping member extending axially along the area of telescoping overlap and being sandwiched in airtight engagement between said joint tube and said intake pipe.
Claim 3
Dependent Claim
15 words
