DETONATING FUSE FOR PENETRATING AMMUNITION Russian patent published in 2008 - IPC F42C1/08 

FIELD: weapons.

SUBSTANCE: detonating fuze contains interrupting-arming circuits, firing circuit with detonating impression cap, located in the spring-actuated small engine, triggering circuit with detonating cap impression mechanism, inertia block with a detent, pyrotechnical press fittings, firing mechanism and at least one spring, installed so that to provide an opportunity for backward movement of inertia block with central sleeve locked in it. Firing mechanism consists of prong, spring and locking ball. The mechanism is located inside the central sleeve. Triggering circuit includes central sleeve with a bore for detent, capable of axial movement relative to inertia block and thrusting against pyrotechnical press fitting in the inertia block.

EFFECT: provision of optimum delay time of detonating fuze triggering, when hitting various barriers with penetrating rounds of different types, with wide range of impact velocity and barrier characteristics.
