Abstract
An initiator for opening a pressurized gas cylinder is disclosed herein. The initiator includes a housing having a first end and a second end, a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing, a spring disposed within the housing between the first end of the housing and the lance, and a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current.
Claims9
An initiator for opening a pressurized gas cylinder, comprising:
- a housing having a first end and a second end;
- a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing;
- a spring disposed within the housing between the first end of the housing and the lance;
- a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current;
- a first anchor point coupled to the lance;
- a second anchor point coupled to the lance;
- and
- a third anchor point coupled to the housing, wherein the wire is configured to enter the housing, wrap around the first anchor point, wrap around the third anchor point, wrap around the second anchor point, and exit the housing.
A system, comprising:
- a compressed gas cylinder;
- and
- an initiator configured to open the compressed gas cylinder, the initiator including:
- a housing having a first end and a second end;
- a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing;
- a spring disposed within the housing between the first end of the housing and the lance;
- a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current;
- a first anchor point coupled to the lance;
- a second anchor point coupled to the lance;
- and
- a third anchor point coupled to the housing, wherein the wire is configured to enter the housing, wrap around the first anchor point, wrap around the third anchor point, wrap around the second anchor point, and exit the housing.
A system, comprising:
- a pressurized cylinder;
- a manifold coupled to the pressurized cylinder;
- and
- an initiator coupled to the manifold and configured to open the pressurized cylinder, the initiator including:
- a housing having a first end and a second end;
- a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing;
- a spring disposed within the housing between the first end of the housing and the lance;
- a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current;
- a first anchor point coupled to the lance;
- a second anchor point coupled to the lance;
- and
- a third anchor point coupled to the housing, wherein the wire is configured to enter the housing, wrap around the first anchor point, wrap around the third anchor point, wrap around the second anchor point, and exit the housing.
