Description
The fuze is composed of two major parts, the fuze body and the nose cap. The body contains the auxiliary detonator plunger, the detonator plunger, the detonator-plunger detents, the anti-creep spring assembly, and the firing train. The auxiliary detonator is surrounded by twenty ball bearings and bears against the bottom of the detonator plunger. Fitted over the top of the detonator plunger is the anti-creep spring assembly consisting of an inner and an outer cup separated by an anti-creep spring. The outer cup will not move, and the inner cup is crimped over the top of the detonator plunger and held in position by the sensitive primer holder. The firing train consists of the sensitive primer, secondary firing pin, secondary primer, delay element, detonator, and booster lead-ins and lead-outs which are out of line in the unarmed position.
The nose cap, which is secured to the end of the body by a threaded joint, houses the sensitive firing pin and firing pin detents. The sensitive firing pin is held in place by two stakes, but is referred to as a "floating" firing pin, since it can move downward slightly. Ninety degrees moved from the two detent are two holes in the nose cap. A locking pin is provided to lock the nose cap in position.
This fuze will function on four inch plate and on water.
The Base Detonating Fuze Mk 19 Mod 1 is fully moisture-resistant, as described for the Base Detonating Fuze Mk 28. This is its only difference from the Mod 0.
