CONTROL VALVE AND AIR STARTING SYSTEM
First Claim
Patent Images
1. A method of slow starting a combustion engine with an air starting system having a source of pressurized air fluidly coupled to an air starter via a control valve, the method comprising:
- supplying bursts of air from the pressure source to the air starter by reciprocating a piston of the control valve between an opened position and a closed position, with selective application of a pull force to the piston to counter, in combination with a push force applied to the piston by the pressurized air, a normally-closing biasing force acting on the piston.

14. A method of operating an air starting system having a pressure source coupled to an air starter via a control valve, the method comprising:
-
supplying bursts of air from the pressure source to the air starter to reciprocate a piston of the control valve between an opened position and a closed position; biasing the piston toward the closed position by applying a biasing force with a biasing element; flowing a fluid from the pressure source to an inlet of the control valve to apply a push force on the piston; generating a pull force on the piston which when combined with the push force is sufficient to overcome the biasing force to move the piston to the opened position; and removing at least one of the push force or the pull force to move the piston to the closed position. - View Dependent Claims (15, 16, 17, 18, 19, 20)
