Abstract
An actuator is disclosed herein. The actuator includes a drive body including a bottom surface, the bottom surface having a first side and an opposing second side, a magneto strictive material disposed within the drive body and contacting the first side of the bottom surface of the drive body, a solenoid disposed within the drive body and surrounding the magneto strictive material, a drive rod extending through the magneto strictive material and through the bottom surface of the drive body, and a spring disposed adjacent the second side of the bottom surface of the drive body, wherein the drive rod extends through the spring.
Claims20
An actuator, comprising:
- a drive body including a bottom surface, the bottom surface having a first side and an opposing second side;
- a magneto strictive material disposed within the drive body with a first end of the magneto strictive material contacting the first side of the bottom surface of the drive body and with a second end of the magneto strictive material opposite the first end remaining unobstructed by the drive body such that the magneto strictive material is configured to extend away from and out through a top surface of the drive body;
- a solenoid disposed within the drive body and surrounding the magneto strictive material;
- a drive rod extending through the magneto strictive material and through the bottom surface of the drive body;
- and
- a spring disposed adjacent the second side of the bottom surface of the drive body, wherein the drive rod extends through the spring.
An actuator, comprising:
- a drive body;
- a solenoid disposed within the drive body;
- a magneto strictive material magnetically coupled to the solenoid and disposed within the drive body with a first end of the magneto strictive material contacting the first side of the bottom surface of the drive body and with a second end of the magneto strictive material opposite the first end remaining unobstructed by the drive body such that the magneto strictive material is configured to extend away from and out through a top surface of the drive body;
- and
- a drive rod extending through the magneto strictive material.
A system, comprising:
- a gas bottle including a neck with an opening in the neck;
- a fracture disk connected to the neck and sealing the neck;
- and
- an actuator configured to open the gas bottle, the actuator including:
- a body having a first end and a second end, the first end connected to the neck of the gas bottle;
- a drive body connected to the second end of the body, the drive body having a bottom surface;
- a magneto strictive material disposed within the drive body with a first end of the magneto strictive material contacting the bottom surface of the drive body and with a second end of the magneto strictive material opposite the first end remaining unobstructed by the drive body such that the magneto strictive material is configured to extend away from and out through a top surface of the drive body;
- a solenoid disposed within the drive body and magnetically coupled to the magneto strictive material;
- and
- a drive rod extending through the magneto strictive material and through the bottom surface of the drive body.
