ABSTRACT:
An assembly includes a piston and a transition arm coupled to the piston. The position of the transition arm is adjustable to vary a stroke of the piston. A balance member is adjustable relative to the transition arm to counterbalance the transition arm in varying positions. A control rod is coupled to the transition arm and the balance member. Linear movement of the control rod moves the transition arm in a first direction to change the stroke of the piston and moves the balance member in a second direction substantially opposite the first direction to counterbalance the transition arm. A method of counterbalancing a variable stroke assembly includes moving a transition arm coupled to a piston to vary a stroke of the piston, and moving a balance member in a direction substantially opposite to the direction of movement of the transition arm to counterbalance the transition arm.
