Abstract

A cartridge retention system includes a retention body, a cartridge assembly, and a retaining flange. The cartridge assembly has a housing coupled to the retention body, a biasing member disposed within the housing, and a piston biased by the biasing member toward the retention body. The retaining flange is coupled to the retention body by the cartridge assembly.

First claim

The invention claimed is:

1. A cartridge retention system, comprising:
a retention body;
a cartridge assembly having a housing coupled to the retention body, wherein the housing is threaded into a threaded bore formed in the retention body, a biasing member disposed within the housing, and a piston biased by the biasing member toward the retention body, wherein the biasing member is disposed between an inner shoulder of the housing and a flange portion of the piston, and wherein a chamber is formed within the retention body below the flange portion of the piston; and
a retaining flange coupled to the retention body by the cartridge assembly.

2. The system of claim 1 , wherein the piston extends through the housing and through a corresponding opening formed in the retaining flange.

3. The system of claim 2 , wherein a flange retaining nut is threaded onto the piston and into engagement with an upper surface of the retaining flange.

4. The system of claim 3 , wherein the biasing member biases the piston, the retaining flange nut, and the retaining flange into engagement with an outer shoulder of a liner.

5. The system of claim 4 , further comprising a spacer coupled to the retention body by one or more bolts.

6. The system of claim 1 , wherein pressurized fluid supplied into the chamber applies a force to the flange portion of the piston against the bias of the biasing member.

7. The system of claim 6 , wherein the flange portion of the piston is disposed within the retention body.

8. The system of claim 7 , wherein the piston extends through the housing and through a corresponding opening formed in the retaining flange.

9. The system of claim 8 , wherein a flange retaining nut is threaded onto the piston and into engagement with an upper surface of the retaining flange.

10. The system of claim 1 , wherein the housing, the biasing member, and the piston are at least partially disposed within the retention body.

11. The system of claim 10 , wherein a flange portion of the piston is disposed within the retention body.

12. A cartridge retention system, comprising:
a retention body;
a cartridge assembly having a housing coupled to the retention body, a biasing member disposed within the housing, and a piston biased by the biasing member toward the retention body, wherein the housing, the biasing member, and the piston are at least partially disposed within the retention body; and
a retaining flange coupled to the retention body by the cartridge assembly.

13. The system of claim 12 , wherein a flange portion of the piston is disposed within the retention body.

14. The system of claim 12 , wherein the housing is threaded into a threaded bore formed in the retention body.

15. The system of claim 12 , wherein the biasing member is disposed between an inner shoulder of the housing and a flange portion of the piston.

16. The system of claim 15 , wherein a chamber is formed within the retention body below the flange portion of the piston.

17. The system of claim 16 , wherein pressurized fluid supplied into the chamber applies a force to the flange portion of the piston against the bias of the biasing member.

18. The system of claim 17 , wherein the piston extends through the housing and through a corresponding opening formed in the retaining flange.

19. The system of claim 18 , wherein a flange retaining nut is threaded onto the piston and into engagement with an upper surface of the retaining flange.

20. The system of claim 19 , wherein the biasing member biases the piston, the retaining flange nut, and the retaining flange into engagement with an outer shoulder of a liner.
