Filed:

Nov 18, 1998

Appl. No.:

09/193884

Inventors:

Lan T. Nguyen - League City TX
Scott D. Ward - Houston TX
Roger Boisjolie - Houston TX

Assignee:

Cooper Cameron Corporation - Houston TX

International Classification:

F16L 2108

US Classification:

285320, 285920, 285322, 285 18

Abstract:

An automatic locking mechanism for a telescoping joint for a riser functions in several modes. In an operating mode, the joint is free to have its inner and outer barrels move with respect to each other without engaging each other in a locking relationship. In a second position, the telescoping joint locks when it is fully retracted. In a third position, the system locks the inner and outer barrels together to hold them in a fixed position. The inner and outer barrels are locked when a movable sleeve is properly positioned to allow spring-loaded dogs to be biased through windows in the sleeve so as to act as a landing shoulder to catch a groove on the outer barrel. By putting the actuating sleeve in a variety of positions, the various modes of the locking assembly can be deployed.

Abstract:

A pressure regulator is provided. In one embodiment, the pressure regulator includes a housing having a supply port for receiving a pressurized medium within the housing and an outlet port for outputting the pressurized medium to a downstream device. The housing of this embodiment also includes a vent port for venting the pressurized medium from the housing. The pressure regulator of this embodiment further includes two pistons disposed within the housing, wherein one piston controls flow of the pressurized medium through the supply port, and the other piston controls flow of the pressurized medium through the vent port, based on the level of pressure within the housing. Other embodiments of pressure regulator devices and systems are also provided.

International Classification:

G05D 16/10

US Classification:

1371163, 13750511, 13750518, 13750526

Abstract:

A pressure regulator is provided. In one embodiment, the pressure regulator includes a body having an internal cavity for receiving a pressurized medium and inlet and outlet ports that enable a pressurized medium to enter the internal cavity at a first pressure and exit at a second pressure. The exemplary pressure regulator also includes a control piston disposed within the internal cavity that is configured to move in response to a change in pressure within the internal cavity. The pressure regulator of this embodiment also includes a damping feature within the internal cavity that is configured to oppose the movement of the control piston. Other embodiments of pressure regulators and systems are also provided.

Assignee:

Cameron International Corporation - Houston TX

International Classification:

F16L 55/04

US Classification:

138 31, 138 30, 137 14

Abstract:

A pressure-compensated accumulator bottle is provided. In one embodiment, the accumulator bottle includes a housing and an interior wall that generally define first, second, and third chambers within the housing. In this embodiment, a spring is disposed in the second chamber and configured to apply a biasing force on a first piston disposed within the first chamber. Further, in this embodiment, an additional piston is disposed within the third chamber and is configured to facilitate balancing of the pressure of a fluid disposed in the second chamber with the pressure of the external environment such that the magnitude of a second biasing force applied on the first piston by the pressure of the fluid depends at least in part on the pressure of the external environment. Hydraulic circuits and systems including a pressure-compensated accumulator bottle are also disclosed.
