TOOL CONNECTION RELEASE SYSTEM
First Claim
1. A tool connection release system, the system comprising:
- a housing having a first portion and a second portion;
a piston disposed at least partially within the housing first portion and at least partially within the housing second portion;
a first fluid chamber including a first pressurized fluid acting against the piston;
a fluid source coupled to the first fluid chamber; and
a second fluid chamber including a second pressurized fluid acting against the piston to oppose the first pressurized fluid and pressure-balance the piston;
wherein addition of a fluid from the fluid source to the pressure-balanced piston causes the piston to move and the first housing portion to separate from the second housing portion.

Abstract
A connection release system for the disconnection of various connections, such as electrical, hydraulic, optical, and/or multi-connector, to a service tool in a high pressure environment. An embodiment of the connection release system includes a first and second housing portion with a piston disposed partially within both the first and second housing portions, the piston having a plurality of threads at an exterior portion of a second end. The system further includes a plurality of fluid chambers disposed in the first housing portion, the fluid chambers are filled with fluid to pressure-balance the piston such that the addition of a pressurized fluid to the pressure-balanced piston causes the piston to move, the exterior threaded portion of the piston to disengage an interior threaded portion within the housing second portion, and allow the first housing portion to separate from the second housing portion.

8. A tool connection release system, the system comprising:
-
a housing having a first portion and a second portion, the first portion being coupled to a cable; a piston having a first end axially disposed at least partially within the housing first portion, and a plurality of threads at a second end; and a release nut disposed within the housing second portion and having a plurality of threads at an interior portion of a first end, a recess at an exterior portion of the first end, a second end, and a plurality of circumferentially disposed slots that pass through the plurality of threads and the recess in the first end, the second end being attached to a portion of the housing second end; wherein the threaded exterior portion of the piston is configured to releasably engage the threaded interior portion of the release nut and the plurality of circumferentially disposed slots is configured to allow the release nut first end to move radially outward and disengage the threaded exterior portion of the piston from the threaded interior portion of the release nut such that the piston and the housing first portion can be separated from the release nut and the housing second portion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A tool connection release system, the system comprising:
-
a plug connector having a first end and a second end, the first end coupled to a cable, and an outer portion of the second end having at least one axial protrusion; an actuation cylinder housing having a first end, a second end, and a plurality of circumferentially spaced galleries, the first end coupled to the plug connector; a piston having a first end, a second end, and a plurality of threads at an exterior portion of the second end, the piston being axially disposed at least partially within the activation cylinder housing and forming a first cavity therein; a piston cap is disposed around the piston and forms a second cavity therein, threadably engages the second end of the actuation cylinder, and is configured to retain the first end of the piston within the actuation cylinder; a motor head having a first end and a second end, an inner portion of the first end having at least one axial recess configured to engage the protrusion on the outer portion of the plug connector second end; a release nut having a plurality of threads at an interior portion of a first end, a recess at an exterior portion of the first end, a second end, and a biasing member disposed in the recess; and a protection sleeve disposed about the release nut and a portion of the piston cap, the sleeve forming a third cavity with the release nut; wherein the piston is configured to axially slide around an outer portion of the motor head; wherein the plurality of threads on the exterior portion of the piston second end is configured to releasably engage the threads on the interior portion of the release nut first end upon addition of a pressurized fluid. - View Dependent Claims (20, 21, 22)
