Abstract

A trigger (20) for opening a valve (50) against fluid pressure has two alternate pivot pins (122, 124). The first pivot point (124) has a relatively higher mechanical advantage to make it easier to push the valve against the fluid pressure.
The second pivot point (122) has a relatively lower mechanical adavantage 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 the fluid pass the valve. The trigger thereby reduces the force required to open the valve without decreasing the range of motion of the valve.
