| 发明名称 | Braking mechanism for a downhole tool | ||
| 摘要 | This invention relates to braking mechanism for a downhole tool such as a steering tool. The braking mechanism comprises: a body adapted for mounting upon the tool;at least one braking member which is movably mounted upon the body;a resilient biasing means biasing the braking member away from the body; anda damping mechanism connected to the braking member, the damping mechanism providing a damping force opposing movements of the braking member relative to the body, the damping force being dependent upon the rate of movement of the braking member. | ||

| 主权项 | 1. A braking mechanism for a downhole tool, the braking mechanism having: a body adapted for mounting upon the tool; at least one braking member which is movably mounted upon the body, the braking member being movable relative to the body continuously during use, the braking member being movable both towards and away from the body; a resilient biasing element biasing the braking member away from the body; and a damping mechanism connected to the braking member, the damping mechanism providing a damping force opposing movement of the braking member towards the body, the damping force being dependent upon the rate of movement of the braking member. | ||
