Abstract

A closing cover assembly for an air spring includes a first portion defining a first internal space constructed and arranged to receive a portion of an air spring. A second portion is integral with and extends from the first portion. The second portion defines a second internal space. A passageway connects the first internal space with the second internal space. A pressure retention valve having a main body is received in the second internal space, with the second portion of the cover defining an outer protective housing for the main body of the pressure retention valve.

First claim

What is claimed is:

1 . A closing cover for an air spring comprising:
a base, a first portion integral with and extending from the base, the first portion defining a first internal space constructed and arranged to receive a portion of an air spring, a second portion, integral with and extending from the first portion, the second portion defining a second internal space constructed and arranged to receive a main body of a pressure retention valve to thereby define an outer protective housing for the main body of the pressure retention valve, and a passageway connecting the first internal space with the second internal space.

2 . The closing cover of claim 1 , wherein the first internal space and the second internal space are disposed on a common axis.

3 . The closing cover of claim 1 , wherein each of the first internal space and the second internal space is generally cylindrical.

4 . The closing cover of claim 1 , wherein each of the base, the first portion and the second portion is composed of aluminum.

5 . The closing cover of claim 1 , wherein each of the base, the first portion and the second portion is composed of steel.

6 . The closing cover of claim 1 , wherein each of the base, the first portion and the second portion is composed of plastic.

7 . The closing cover of claim 1 , in combination with the pressure retention valve with the main body thereof received in the second internal space.

8 . The combination of claim 7 , wherein the pressure retention valve includes a flange engaging an end of the second portion of the cover.

9 . The combination of claim 7 , wherein a portion of the main body includes threads engaged with threads of the second portion of the cover.

10 . The combination of claim 9 , further comprising an O-ring between the pressure retention valve and the second portion of the cover and adjacent to the engaged threads.

11 . The combination of claim 9 , wherein the main body includes a valve member of the valve.

12 . A closing cover assembly for an air spring comprising:
a cover comprising:
a first portion defining a first internal space constructed and arranged to receive a portion of an air spring,
a second portion, integral with and extending from the first portion, the second portion defining a second internal space, and
a passageway connecting the first internal space with the second internal space, and
a pressure retention valve having a main body received in the second internal space, with the second portion of the cover defining an outer protective housing for the main body of the pressure retention valve.

13 . The closing cover assembly of claim 12 , wherein the first internal space and the second internal space are disposed on a common axis.

14 . The closing cover assembly of claim 12 , wherein each of the first internal space and the second internal space is generally cylindrical.

15 . The closing cover assembly of claim 12 , wherein each of the base, the first portion and the second portion is composed of aluminum, steel or plastic.

16 . The closing cover assembly of claim 12 , wherein the pressure retention valve includes a flange engaging an end of the second portion of the cover.

17 . The closing cover assembly of claim 12 , wherein a portion of the main body includes threads engaged with threads of the second portion of the cover.

18 . The closing cover assembly of claim 17 , further comprising an O-ring between the pressure retention valve and the second portion of the cover and adjacent to the engaged threads.

19 . The closing cover assembly of claim 12 , wherein the main body includes a valve member of the valve.
