Abstract

Two cylinder chambers are provided in a housing, each of these chambers containing a piston. Pins project, as piston rods, from the pistons in differing directions. A duct is located in a zone between the pistons. This duct is in communication with a compressed gas cartridge. Upon triggering of the compressed gas cartridge, the released gas moves the pistons apart so that the pins are moved simultaneously or in accordance with a predetermined sequence of operations.
