A low-shock separation device is characterized in that an internal locking structure is unlocked and a bolt is separated by operating a specific part of components thereof using high pressure that is generated by combustion of powder.
Claims7
A low-shock separation device comprising:
- a housing having open top and bottom and an internal receiving space;
- a cylinder disposed in the receiving space through the top of the housing and having a top hole and a bottom hole communicating with the top hole and larger in cross-sectional area than the top hole;
- a housing cap fitted in a space between the housing and the cylinder and closing the top of the housing;
- a piston disposed in the bottom hole of the cylinder;
- a pressure cartridge partially inserted in the top hole and closing an upper end of the top hole;
- and
- a bolt partially inserted in the bottom hole through the bottom of the housing, closing a lower end of the bottom hole, and kept in the bottom hole by a holder,
- wherein a passage attenuating a collision between the cylinder and the housing cap is formed by filling a space between the cylinder and the housing cap with high pressure gas, and the passage is formed when the cylinder is moved toward the pressure cartridge by high pressure that is generated when the pressure cartridge is operated.
