Abstract
A downhole tool for use in a subterranean well can include an electric motor, a motor carrier, and a compressed gas chamber. The motor may be axially reciprocably received in the motor carrier. The compressed gas chamber may decrease in volume in response to displacement of the motor in an axial direction relative to the motor carrier. The chamber may be formed radially between the motor and the motor carrier.
Claims19
A downhole tool for use in a subterranean well, the downhole tool comprising:
- an electric motor;
- a motor carrier, the motor being axially reciprocably received in the motor carrier;
- a compressed gas chamber configured to decrease in volume in response to displacement of the motor in a first axial direction relative to the motor carrier;
- and
- a spring that biases the motor carrier in a second axial direction opposite to the first axial direction.

- an electric motor;
- a motor carrier, the motor being axially reciprocably received in the motor carrier;
- and
- a compressed gas chamber configured to decrease in volume in response to displacement of the motor in a first axial direction relative to the motor carrier, the entire chamber being formed radially between the motor and the motor carrier, in which pressure within the chamber increases in response to the decrease in volume.
