Description
The oldest Soviet fuze of its type, the UV is an instantaneous, mechanical, pull type containing a spring-loaded striker with a striker retaining pin release. It consists of a metal tube, about 2 inches long and 1/2 inch wide, containing a spring-loaded striker. The end of the striker bolt projects through the top of the fuze housing and has two holes through it. The outermost hole is for a transit pin while the fuze is being carried uncocked. The inner hole is exposed by pulling on the striker end. It is the hole through which the striker-retaining pin is inserted to hold the striker in the armed or cocked position. A percussion cap is built into the base of the fuze. The base is narrowed and just large enough in diameter to permit a nonelectric detonator to be inserted, open end first.
This fuze was used in World War II Soviet pull action mines and booby traps. It was replaced by the MUV pull fuze.
Functioning
Pull of a few pounds on the striker-retaining pin pulls the pin out of the striker, releasing the striker against the percussion cap.
