What is claimed is:
1. An assembly, comprising:
a piston,
a transition arm coupled to the piston, a position of the transition arm being adjustable to vary a stroke of the piston, and
a balance member adjustable relative to the transition arm to counterbalance the transition arm in varying positions.
2. The assembly of claim 1 further comprising a control assembly coupling the balance member to the transition arm.
3. The assembly of claim 2 wherein the control assembly includes a control rod having a first end region coupled to the transition arm and a second end region coupled to the balance member.
4. A. The assembly of claim 3 wherein the control rod includes linear gear teeth at the first and second ends.
5. The assembly of claim 3 wherein the control assembly includes a gear block receiving a nose pin of the transition arm, and a gear coupling the gear block to the first end of the control rod.
6. The assembly of claim 3 wherein the control assembly includes a gear coupling the second end of the control rod to the balance member.
7. The assembly of claim 6 wherein the balance member includes gear teeth mating with the gear coupling the second end of the control rod to the balance member.
8. The assembly of claim 2 wherein the control assembly includes a control rod with linear gear teeth, and a gear mating with the gear teeth.
9. The assembly of claim 8 wherein the control assembly further comprises a gear block attached to the transition arm and mating with the gear such that linear movement of the control rod rotates the gear to move the gear block and the transition arm to change the stroke of the piston.
10. The assembly of claim 8 wherein the balance member includes gear teeth mating with the gear such that linear movement of the control rod rotates the gear to move the balance member.
11. The assembly of claim 1 further comprising
a control rod with linear gear teeth,
a first gear mating with the gear teeth in a first section of the control rod,
a second gear mating with the gear teeth in a second section of the control rod,
a gear block attached to the transition arm and mating with the first gear such that linear movement of the control rod rotates the first gear to move the gear block and the transition arm in a first direction to change the stroke of the piston, and
the balance member includes gear teeth mating with the second gear such that the linear movement of the control rod rotates the second gear to move the balance member in a second direction substantially opposite the first direction to counterbalance the transition arm.
12. An assembly, comprising:
at least two pistons,
a transition arm coupled to each of the at least two pistons,
a rotatable member coupled to the transition arm, a radial position of the transition arm relative to an axis of rotation of the rotatable member being adjustable,
a balance member adjustable relative to the transition arm to counterbalance the transition arm in varying positions, and
a control rod having a first end coupled to the transition arm and a second end coupled to the balance member such that movement of the control rod varies the position of the transition arm and the balance member.
13. The assembly of claim 12 wherein the control rod is coupled to the transition arm and the balance member such that movement of the control rod results in movement of transition arm and balance member in substantially opposite directions.
14. A method of counterbalancing a variable stroke assembly, comprising:
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.
