The air turbine starter valve of claim 8, wherein the upper surface of the piston defines at two intersecting grooves, one groove extending from a position near to the opening of the housing when the piston is in the first position. 10. The air valve of claim 9, wherein the upper surface of the piston is beveled about its perimeter to form a circumferential air channel with the housing when the piston is in the first position. 11. An air turbine starter system comprising: An air turbine starter including: A housing defining an opening for accepting drive air flow; A turbine mechanism mounted in the housing in a position to receive the drive air flow; A gear box operatively connected to the turbine mechanism; An output shaft operatively connected to the gear box; and A clutch assembly connected to the output shaft; A valve body with an interior surface defining an inlet, an outlet and a passageway therebetween for start air flow; A valve gate mounted in the passageway for movement between an open and a closed position; An actuator operably coupled to the valve gate, the actuator including: A housing having an internal surface; A piston slidably mounted within the housing to move between a first position and a second position, whereby the piston has an upper surface cooperatively defining a chamber with the housing, the chamber being variable in volume depending on the location of the piston, but having a smaller volume when the piston is in its first position; and An opening in the housing to provide fluid communication to the chamber; A regulator mechanism operatively connected to the opening in the housing to selectively provide air flow to the chamber, and An arm mechanism operatively connected between the piston to the valve gate; Wherein the volume of the chamber is less than 0.1 cubic inches when the piston is in the first position. 12. An air turbine starter valve actuator comprising: A housing having an internal surface; A piston slidably mounted within the housing to move between a first position and a second position, whereby the piston has an upper surface cooperatively defining a chamber with the housing, the chamber being variable in volume depending on the location of the piston, but having a smaller volume when the piston is in its first position; An opening in the housing to provide fluid communication to the chamber; A regulator mechanism operatively connected to the opening in the housing to selectively provide air flow to the chamber; and An arm mechanism operatively connected between the piston to the valve gate; Wherein the volume of the chamber is less than 0.1 cubic inches when the piston is in the first position. 13. The air valve of claim 12, wherein the volume of the chamber is less than 0.05 cubic inches when the piston is in the first position. 14. The air valve of claim 12, wherein the volume of the chamber is less than 0.003 cubic inches when the piston is in the first position. 15.
