Ampoule with starting fuel for igniting liquid rocket propellant components

摘要

The invention relates to the field of automatic equipment and, in particular, to devices for chemical ignition of LRE propellant components. The ampoule comprises a body, diaphragm units mounted at the body inlet and outlet, each of which is made as a piston made as a single part with a diaphragm. The peripheral part of the diaphragm is fixed in an air-tight manner to the body under a guide element in which the body is mounted. The piston has a stem extending into a guide bush. Furthermore, a device for filling the ampoule with fuel is located in a partition of the body inside the ampoule. A guaranteed cutting of the diaphragm along the entire perimeter and reproduction of hydraulic characteristics for the flow part of the ampoule are achieved in this ampoule design.
