Abstract

A pass-through seal may seal a component extending between a first member and a second member in a vehicle. The pass-through seal may define a core opening and have a varying outer profile. The core opening receives the component at a predefined angle relative to an aperture defined by the first member. The core opening supports the component at the predefined angle at one end and has a snug fit with the component at the other end. The varying outer profile is configured to create an interference fit with the aperture defined by the first member at one end and to be larger than the aperture at the other end.

First claim

What is claimed is:

1. A pass-through seal for sealing a component extending between a first member and a second member in a vehicle, the pass-through seal comprising:
two or more portions fixedly coupled and defining a core opening, wherein the core opening receives the component at a predefined angle relative to an aperture defined by the first member, wherein the two or more portions include:
a first portion that has an outer profile configured to create an interference fit with the aperture defined by the first member, and the first portion defines a first opening that forms part of the core opening and supports the component at the predefined angle, and
a second portion that has an outer profile larger than the aperture of the first member to prevent the second portion from passing through the aperture, and the second portion defines a second opening that forms part of the core opening and fits snuggly around the component;

wherein the core opening receives the component at an angle that is non-orthogonal to the aperture defined by the first member.

2. The pass-through seal of claim 1 wherein the second portion abuts against a surface and the second member.

3. The pass-through seal of claim 1 wherein:
the component includes at least two sub components that extend between the first member and the second member, and
the two or more portions define a core opening for each of the at least two subcomponents.

4. The pass-through seal of claim 1 wherein the two or more portions further include at least one more portions different from the first portion and the second portion, and the at least one more of the portions is arranged between the first portion and the second portion.

5. The pass-through seal of claim 1 wherein the first member is a floorboard of a vehicle.

6. A system for sealing a thermostatic expansion valve TXV assembly to a vehicle firewall, the system comprising:
a pass-through seal that:
interfaces with a flange disposed at an end of an engine bay conduit that directs the TXV assembly toward the firewall;
receives the TXV assembly at a predefined angle relative to an aperture defined by the firewall;
includes an outer profile that is orthogonal relative to the firewall aperture;
is configured to be inserted into the firewall aperture; and
supports the TXV assembly at the predefined angle and frictionally seals the TXV assembly to the firewall when the pass-through seal is inserted into the firewall aperture;
wherein the pass-through seal receives the TXV assembly at an angle that is non-orthogonal relative to the firewall.

7. The system of claim 6 wherein the pass-through seal further comprises a first portion comprising a first opening and a second portion comprising a second opening.

8. The system of claim 7 wherein the first portion includes an outer profile configured to create an interference fit with the firewall when the pass-through seal is inserted into the firewall aperture.

9. The system of claim 7 wherein the second portion includes an outer profile configured to prevent the second portion from passing through the firewall when the pass-through seal is inserted into the firewall aperture and wherein the second portion interfaces with the flange when the first portion is inserted into the firewall aperture.

10. The system of claim 7 wherein the second opening is configured to fit snug around the TXV and the first opening is configured to support the TXV at the predefined angle.

11. A system for sealing a thermostatic expansion valve TXV assembly to a vehicle firewall, the system comprising:
an engine bay conduit that directs the TXV assembly toward an engine bay side of the firewall, the conduit having a flange disposed at an end of the conduit that faces the engine bay side of the firewall;
a firewall aperture defined by the firewall; and
a pass-through seal that:
receives the TXV assembly at a predefined angle relative to the firewall aperture;
includes an outer profile that is non-orthogonal relative to the firewall aperture; and
frictionally fastens the TXV assembly to the firewall when the pass-through seal is inserted into the firewall aperture;
wherein the pass-through seal receives the TXV assembly at an angle that is non-orthogonal relative to the firewall.

12. The system of claim 11 wherein the pass-through seal further comprises a first portion and a second portion.

13. The system of claim 12 wherein the first portion includes an outer profile configured to create an interference fit with the firewall when the pass-through seal is inserted into the firewall aperture.

14. The system of claim 12 wherein the second portion includes an outer profile configured to prevent the second portion from passing through the firewall when the pass-through seal is inserted into the firewall aperture.

15. The system of claim 12 wherein the first portion includes a first opening and the second portion includes a second opening.

16. The system of claim 15 wherein the second opening is configured to fit snug around the TXV and the first opening is configured to support the TXV at the predefined angle.
