Abstract

An end plate for an expansion valve of a refrigeration circuit. The end plate includes a pair of slots or apertures, each of the slots configured to receive a tube or hose therein. Further, a pair of apertures is formed in the end plate extending from a first surface to a second surface thereof, each of the apertures configured to receive a fastener therein. The first face of the end plate includes a pair of protuberances extending outwardly from the first face. The protuberances are formed adjacent and laterally outwardly from the pair of apertures. The protuberances act as spacers and abut a surface of a housing of the expansion valve and may create a gap between the housing and the end plate to ensure equal clamping loading and militate against damage to a seal element between the housing and the end plate due to misalignment.

First claim

What is claimed is:

1. An end plate of a fluid handling assembly comprising:
a plate having a first tube aperture and a second tube aperture formed therein, each of the first tube aperture and the second tube aperture configured to receive a tube therein, the first tube aperture formed at a first end of the plate and the second tube aperture formed at a second end of the plate, wherein the plate includes a first edge and a second edge extending between the first end and the second end of the plate;
a first protuberance formed on a first surface of the plate;
a second protuberance formed on the first surface of the plate, wherein the first protuberance and the second protuberance are positioned intermediate the first tube aperture and the second tube aperture; and
a pair of threaded apertures formed in the plate intermediate the first tube aperture and the second tube aperture, and wherein the first protuberance extends along the first edge of the plate adjacent one of the threaded apertures and the second protuberance extends along the second edge of the plate adjacent another one of the threaded apertures.

2. The end plate of claim 1 , wherein the first protuberance and the second protuberance are formed as a unitary structure with the plate.

3. The end plate of claim 2 , wherein the first protuberance and the second protuberance are formed from a same material as the plate.

4. The end plate of claim 1 , wherein the first protuberance and the second protuberance are formed separately from the plate and joined with the plate.

5. The end plate of claim 4 , wherein the first protuberance and the second protuberance are formed from a material different from the plate.

6. A fluid handling assembly comprising:
a housing configured to convey a fluid therethrough in a plurality of apertures formed therein, wherein the housing includes an outer face;
an end plate having a first tube aperture and a second tube aperture formed therein, each of the first tube aperture and the second tube aperture configured to receive a tube therein, the tube in fluid communication with one of the plurality of apertures formed in the housing, the first tube aperture formed at a first end of the end plate and the second tube aperture formed at a second end of the end plate;
a first protuberance formed on a first surface of the end plate, the first protuberance disposed intermediate the housing and the end plate; and
a second protuberance formed on the first surface of the end plate intermediate the housing and the end plate, wherein at least one of the first protuberance and the second protuberance abuts the outer face of the housing.

7. The fluid handling assembly of claim 6 , wherein the first protuberance and the second protuberance are positioned intermediate the first tube aperture and the second tube aperture.

8. The fluid handling assembly of claim 7 , further comprising a pair of fastener apertures formed in the housing and a pair of threaded apertures formed in the end plate, wherein a bolt is received in the pair of fastener apertures and the pair of threaded apertures to couple the end plate to the housing.

9. The fluid handling assembly of claim 6 , wherein the housing is configured to be coupled to and in fluid communication with one of a condenser of a refrigeration circuit, a heat exchanger, a battery chiller, and an air conditioning component, a heating component, and a cooling component.

10. An expansion valve assembly comprising:
a housing configured to convey a fluid therethrough in a plurality of apertures formed therein, wherein the housing includes a first outer face and a second outer face;
a first end plate disposed adjacent the first outer face and coupled to the housing, the first end plate having a first aperture and a second aperture formed therein, each of the first aperture and the second aperture configured to receive a tube therein;
a second end plate disposed adjacent the second outer face and coupled to the housing, the second end plate having a first tube aperture and a second tube aperture formed therein, each of the first tube aperture and the second tube aperture configured to receive a tube therein, the first tube aperture formed at a first end of the second end plate and the second tube aperture formed at a second end of the second end plate;
a first protuberance formed on a first surface of the second end plate; and
a second protuberance formed on the first surface of the second end plate, wherein the first protuberance and the second protuberance are disposed intermediate the housing and the second end plate, and wherein at least one of the first protuberance and the second protuberance abuts the second outer face of the housing.

11. The expansion valve assembly of claim 10 , wherein the first protuberance and the second protuberance are positioned intermediate the first tube aperture and the second tube aperture.

12. The expansion valve assembly of claim 11 , further comprising a pair of fastener apertures formed in the housing wherein a bolt is received in each of the pair of fastener apertures and a pair of threaded apertures to couple the second end plate to the housing.

13. The expansion valve assembly of claim 10 , wherein the housing is one of an electric expansion valve and a thermal expansion valve.

14. The expansion valve assembly of claim 10 , wherein the second end plate includes a first edge and a second edge extending between the first end and the second end of the second end plate, and the first protuberance is formed adjacent the first edge and the second protuberance is formed adjacent the second edge.

15. The expansion valve assembly of claim 10 , wherein the first protuberance and the second protuberance are formed as a unitary structure with the second end plate.

16. The expansion valve assembly of claim 15 , wherein the first protuberance and the second protuberance are formed from a same material as the second end plate.

17. The expansion valve assembly of claim 10 , wherein the first protuberance and the second protuberance are formed separately from the second end plate and joined with the second end plate.

18. The expansion valve assembly of claim 17 , wherein the first protuberance and the second protuberance are formed from a material different from the second end plate.
