Abstract
The improved shock actuated sensor is used with shock activation valves which have a shock activation control mechanism. The control mechanism includes a pedestal with a vertical tube disposed thereround and a weight in the form of a ball supported on the pedestal upper end. When a shock or vibration force is experienced the ball is displaced horizontally from a rest position to a side of the control mechanism where it engages the vertical tube that causes the valve to close. The improvement includes a pedestal upper end with a circumferential step to aid the ball in engaging the vertical tube to activate the valve closing. The step allows gravity, in addition to the shock force, to urge the ball to move the vertical tube. The pedestal upper end may also have a recess in the form of an open cylindrical recess to support the ball.
