Abstract
Abstract A connection provides a fluid tight communication between a valve and a tube. The valve includes a first surface, a second surface, and an aperture extending through the valve between the first and second surfaces. The tube includes an end portion terminating at an edge. The end portion penetrates the first surface, extends through the aperture, and is deformed so as to engage the second surface.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
67 words
A connection for communicating a fluid, the connection comprising: a valve including a first surface, a second surface, and an aperture extending through the valve between the first and second surfaces; and a tube including an undeformed end portion terminating at an annular edge, the end portion penetrating the first surface and extending through the aperture, and the end portion being deformed to engage the second surface.
Claim 2
Dependent Claim
67 words
A connection for communicating a fluid, the connection comprising: a valve including a first surface, a second surface, and an aperture extending through the valve between the first and second surfaces; and a tube including an undeformed end portion terminating at an annular edge, the end portion penetrating the first surface and extending through the aperture, and the end portion being deformed to engage the second surface.
Claim 3
Dependent Claim
19 words
The connection according to claim 1 , wherein the tube further includes a flange contiguously engaging the first surface.
Claim 4
Dependent Claim
13 words
The connection according to claim 1 , wherein the second surface is cylindrical.
Claim 5
Dependent Claim
30 words
The connection according to claim 3 , wherein an intersection of the aperture and the second surfaces is configured as a saddle, and the end portion extends through the saddle.
Claim 6
Dependent Claim
22 words
The connection according to claim 4 , wherein the end portion includes a deformation aligned with a minor axis of the saddle.
Claim 7
Dependent Claim
19 words
The connection according to claim 4 , wherein the aperture includes a taper and the saddle includes a chamfer.
Claim 8
Dependent Claim
16 words
The connection according to claim 1 , wherein the end portion includes at least one deformation.
Claim 9
Dependent Claim
14 words
The connection according to claim 7 , wherein the end portion includes four deformations.
Claim 10
Dependent Claim
27 words
The connection according to claim 8 , wherein the tube includes a central longitudinal axis, and the four deformations are distributed at equiangular intervals around the axis.
Claim 11
Dependent Claim
73 words
A connection for communicating exhaust gas, the connection comprising: an exhaust gas recirculation valve assembly having an exterior surface and an interior surface defining a cavity, and having an aperture extending between the interior and exterior surfaces; and a differential pressure tube having an undeformed end portion terminating at an annular edge, the end portion penetrating the exterior surface, extending through the aperture, and being deformed so as to engage the interior surface.
Claim 12
Dependent Claim
73 words
A connection for communicating exhaust gas, the connection comprising: an exhaust gas recirculation valve assembly having an exterior surface and an interior surface defining a cavity, and having an aperture extending between the interior and exterior surfaces; and a differential pressure tube having an undeformed end portion terminating at an annular edge, the end portion penetrating the exterior surface, extending through the aperture, and being deformed so as to engage the interior surface.
Claim 13
Dependent Claim
16 words
The connection according to claim 10 wherein the interior surface of the cavity is generally cylindrical.
Claim 14
Dependent Claim
29 words
The connection according to claim 11 , wherein an intersection of the aperture and the interior surface is configured as a saddle, the end portion extends through the saddle.
Claim 15
Dependent Claim
53 words
The connection according to claim 12 , wherein the differential pressure tube also has a flange contiguously engaging the exterior surface, the end portion is deformed at two points aligned along a minor axis of the saddle, and at least one of the saddle, the aperture, and the second body includes a taper.
Claim 16
Independent Claim
77 words
A method of connecting a tube to a valve, the tube including an undeformed end portion terminating at an annular edge, and the valve including a first surface, a second surface, and an aperture extending through the valve between the first and second surfaces, the method comprising: arranging the undeformed end portion and annular edge to penetrate the first surface and to extend through the aperture; and deforming the end portion to contiguously engage the second surface.
Claim 17
Independent Claim
77 words
A method of connecting a tube to a valve, the tube including an undeformed end portion terminating at an annular edge, and the valve including a first surface, a second surface, and an aperture extending through the valve between the first and second surfaces, the method comprising: arranging the undeformed end portion and annular edge to penetrate the first surface and to extend through the aperture; and deforming the end portion to contiguously engage the second surface.
Claim 18
Dependent Claim
18 words
