ABSTRACT:
A trigger for opening a valve against fluid pressure has two alternate pivot points. The first pivot point has a relatively higher mechanical advantage to make it easier to push the valve against the fluid pressure. The second pivot point has a relatively lower mechanical advantage to increase the distance travelled by the valve in response to further movement of the trigger to make it easier to control the flow of fluid pass the valve. The trigger thereby reduces the force required to open the valve without decreasing the range of motion of the valve.
