PYROLOCK WITH PYROGAS SHOCK ABSORPTION Russian patent published in 2009 - IPC F42B15/36 

FIELD: weapons.

SUBSTANCE: invention is related to the field of rocket and space engineering and may be used for connection and further disconnection of rocket stages, release of head fairing or separation of effective load (for instance, spacecraft). Pyrolock comprises body, bolt with groove, dowels inserted in groove, cartridge that locks dowels, working piston, intermediate piston. Working piston is installed concentrically with cartridge with the possibility of motion in it and along guide surfaces of body. Cartridge is equipped with the following components that interact with each other with the possibility of its fixation in initial position against displacements relative to body - thrust land, spring split ring, spring joined with cartridge with the possibility of interaction with working piston, and braking device. Intermediate piston is installed in body with the possibility of displacement, and cartridge is installed inside intermediate piston, area of which is more than working piston area. Braking device is installed with the possibility to block reverse motion of cartridge.

EFFECT: provides for increased reliability of connection, reduction of impact loads in the moment of separation and expansion of arsenal of applied technical facilities.
