Air transfer system
First Claim
1. A connector system for joining two members of a fluid-transfer duct that approach each other from opposite directions, comprising:
- a first tubular member having at least one end;
an elastomeric seal surrounding the outside of the end of the first tubular member;
a second tubular member having at least one end, the end of the second tubular member surrounding the end of the first tubular member and a portion of the elastomeric seal, another portion of the elastomeric seal extending axially beyond the end of the second tubular member; and
a clamp surrounding the portion of the elastomeric seal that extends beyond the end of the second tubular member, the clamp compressing the seal onto the first tubular member so as to form an interference fit between the seal and the first tubular member sufficient to prevent the first tubular member from being withdrawn axially from the seal, the clamp having means for non-compressibly engaging the second tubular member for preventing the second tubular member from being withdrawn from around the seal.

Abstract
An air flow conduit system is presented for air flow communicatoin between an air filter mechanism and an engine intake manifold. The conduit system comprises substantially rigid straight conduit members joined in fluid communication by connector systems having elbow-shaped conduit members. A narrow end of a conduit member is received within a broad end of a next adjacent conduit member. Sealing engagement occurs by means of an elastomeric seal member having ribs thereon positioned radially between the inner and outer conduits. A preferred rib arrangement is provided, to insure a flexible, multipoint, seal system.

7. A connector system for joining two members of a fluid-transfer duct that approach each other from opposite directions, comprising:
-
a first tubular member having at least one end; an elastomeric seal surrounding the outside of the end of the first tubular member; a second tubular member having at least one end, the end of the second tubular member surrounding the end of the first tubular member and a portion of the elastomeric seal, another portion of the elastomeric seal extending axially beyond the end of the second tubular member, wherein the end of the second tubular member has an inner contour including a radially outwardly projecting lip and a cavity behind said lip, and wherein the seal has an outer contour matching an inner contour of the cavity and lip; and a clamp surrounding the portion of the elastomeric seal that extends beyond the end of the second tubular member, the clamp compressing the seal onto the first tubular member so as to form an interference fit between the seal and the first tubular member sufficient to prevent the first tubular member from being withdrawn axially from the seal, the clamp having means for engaging the second tubular member for preventing the second tubular member from being withdrawn from around the seal.

8. A connector system for joining two members of a fluid-transfer duct that approach each other from opposite directions, comprising:
-
a first tubular member having at least one end; an elastomeric seal surrounding the outside of the ned of the first tubular member; a second tubular member having at least one end, the end of the second tubular member surrounding the end of the first tubular member and a portion of the elastomeric seal, another portion of the elastomeric seal extending axially beyond the end of the second tubular member; and a clamp surrounding the portion of the elastomeric seal that extends beyond the end of the second tubular member, the clamp compressing the seal onto the first tubular member so as to form an interference fit between the seal and the first tubular member sufficient to prevent the first tubular member from being withdrawn axially from the seal, the clamp having means for engaging the second tubular member for preventing the second tubular member from being withdrawn from around the seal;
wherein the end of the second tubular member has a first particular contour, and the clamp has a second particular contour, the first and second contours dimensioned so as to lock with each other when the clamp is installed over the elastomeric seal, to thereby prevent the second tubular member from being withdrawn axially away from the clamp; and
wherein the clamp and second tubular member are dimensioned so that there is a gap between them at all points during nominal conditions. - View Dependent Claims (9)

10. A connector system for joining two members of a fluid-transfer duct that approach each other form opposite directions, comprising:
-
a first tubular member having at least one end; an elastomeric seal surrounding the outside of the end of the first tubular member; a second tubular member having at least one end, the end of the second tubular member surrounding the end of the first tubular member and a portion of the elastomeric seal, another portion of the elastomeric seal extending axially beyond the end of the second tubular member wherein the elastomeric seal has an outer surface with ribs extending therefrom, the ribs and the end of the second tubular member being dimensioned so that, when the system is assembled, the ribs are compressed by differing amounts; and a clamp surrounding the portion of the elastomeric seal that extends beyond the end of the second tubular member, the clamp compressing the seal onto the first tubular member so as to form an interference fit between the seal and the first tubular member sufficient to prevent the first tubular member from being withdrawn axially from the seal, the clamp having means for engaging the second tubular member for preventing the second tubular member from being withdrawn from around the seal.
