Abstract: In a safety valve actuating mechanism there is included a valve operating means, a biasing means, a lever means, a support means, a cam follower means, a first cam member and a second cam member. The valve operating means is movable between a first position and a second position while being biased toward the second position by the biasing means. The lever means is operably connected to the valve operating means and movable at least between a first fulcrum point and a second fulcrum point. The support means releasably supports the lever means at the first fulcrum point. The first and second cam members are spaced adjacent to the cam follower means which is operably connected to the lever means. The first and second cam members and the cam follower means are adapted to control the movement of the valve operating means with the lever means positioned at either the first fulcrum point or the second fulcrum point.
