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. A fluid supply is operably coupled to the first fluid input and means are provided for rotating the shaft at a constant speed. As pressure of the fluid increases, the stroke of the piston increases, thereby generating a longer piston stroke, while the speed of the rotating shaft remains constant.

Abstract translation: 为可变行程电机提供流体阀系统。 阀具有形成气缸的壳体，输入到气缸中的第一流体输入，从气缸外部输出的第一流体输出，输入到气缸中的第二流体输出，以及从气缸外部输出的第二流体输出。 在气缸内设有设有槽的轴。 当轴旋转到第一位置时，第一流体输入和第一流体输出之间的流体连通被切断，同时第二流体输入和第二流体输出之间的流体连通打开。 当轴旋转到第二位置时，第一流体输入和第一流体输出之间的连通被打开，而第二流体输入和第二流体输出之间的连通被切断。 该装置优选地连接到与第一流体输出端和第二流体输入端流体连通的驱动气缸。 活塞设在驱动缸内。 流体供应器可操作地联接到第一流体输入端，并且提供用于以恒定速度旋转轴的装置。 当流体的压力增加时，活塞的行程增加，从而产生更长的活塞行程，同时旋转轴的速度保持恒定。
