Abstract
A releasing device for rocket fuel lines, arranged between a tank outlet and a shutoff valve, which releases the flow path at a defined, tank-side overpressure, with a piston-like bursting element. A disk is provided with a predetermined breaking point and with a clamping flange, as well as a guide rod that is rigidly attached to the disk, and a catching basket that is permeable to flow and fixes the disk in a positive-locking manner after rupture and axial movement. The bursting element is assembled by welding from two parts, namely, the disk with the clamping flange and the predetermined breaking point as one part, and the guide rod with the disk seat as the other part, the disk with the clamping flange is manufactured by machining from a cold-worked, weldable plate material with low breaking strength, the guide rod is manufactured by machining from the rod stock of which the disk was made or of a weldable material having a higher strength, and the predetermined breaking point is manufactured by machining as a one-sided notch on the side of the bursting element facing away from the tank.
