Abstract:

A ram for a blowout preventer has a pressure chamber having a piston movably disposed therein, and a charge disposed at one end of the pressure chamber. A gate is coupled to the piston on a side opposed to the charge. The gate is arranged to move across a through bore in a housing disposed at an opposed end of the pressure chamber. A coupling between the piston and the gate has sufficient strength to transfer kinetic energy of the gate to the piston.
