Abstract (en)
[origin: DE4433212C1] The hydraulic circuit is pressurised by the gas of a pyrotechnic generator transmitted via a drive plate (5), spring (6) and plunger (7). The generator consists of a propellant charge (4a) within a combustion chamber (4) which is fired electronically (13), using coil, plate or gas spring as convenient. All parts are held in a housing (3) exchangeably inserted in a surround wall (2), and the plunger acts directly on the hydraulic circuit oil (2a) in a movement limited by the shoulder (16) at the end of the housing. The drive plate moves within limits imposed by an arrester (15) provided in the housing and the combustion chamber is enclosed in a hermetically sealed gas bellows. The electronic charge firing system charges hot wire to ignite the charge etc. This loads the plate which pressurises the oil via sprig and plunger within mechanically permitted limits (15,16), using the spring to maintain the oil pressure.
