Abstract: A fluid valve system is provided for a variable stroke motor. The valve has a housing forming a cylinder, a first fluid input into the cylinder, a first fluid output out of the cylinder, a second fluid input into the cylinder, and a second fluid output out of the cylinder. Provided within the cylinder is a shaft provided with slots. As the shaft rotates into a first position, fluid communication between the first fluid input and the first fluid output is shut off, while fluid communication between the second fluid input and second fluid output is opened. As the shaft rotates to a second position, communication between the first fluid input and first fluid output is opened, while the communication between the second fluid input and the second fluid output is shut off. The device is preferably hooked up to a drive cylinder in fluid communication with the first fluid output and the second fluid input. A piston is provided within the drive cylinder.
