Description
The MV-5 pressure fuze is an instantaneous, mechanical, pressure type containing a spring-loaded striker with a ball release. It has a metallic pressure cap and a metallic body. A plastic model of this fuze, called the MV-5K, exists in the Soviet Army.
This fuze is the most commonly employed Soviet pressure fuze and is used in the following mines: the TM-41, TM-44, TMB-1, TMB-2, TMS-B, and TMD-B antitank mines; and the PMZ-40 and horseshoe dual-purpose mines.
In World War II and the Korean War, it was found in many types of improvised mines.
Functioning
Pressure of at least 22 pounds on the metallic pressure cap depresses it and at the same time compresses the striker spring, until the striker-retaining ball moves into the ball-escape recess in the metallic pressure cap and releases the striker against the percussion cap.
