Delay detonator










Image Number 2 for United States Patent #4817530.

A nonelectric delay detonator has, in a casing, a secondary charge as well as a delay device. The delay detonator is initiated by an ignition transfer hose extending into the casing. A partition is arranged between a hose end and the delay device. Ignition of the delay device is effected by the hose by impact or heat. An auxiliary charge (e.g. a primer cap) is located on the other side of the partition, this auxiliary charge ignites a delay charge of the delay device. In this way, the delay device burns in a closed system from which gas and pressure cannot escape into the hose. Thereby the scattering width of the delay times of the detonator is reduced.
