Abstract

156,332. Olson, C. J. Oct. 7, 1919. Automatic gear. - An automatic valve for motors, portable drills, &c. is operated by back pressure of power fluid to regulate pressure according to load. The valve casing consists of a cylinder 30 with ports at each end, those at the engine end being regulated by a piston valve 40 closed at one end and having a toothed rim at its other end coacting with a similar rim on a fixed sleeve 47. The pressure on the valve is regulated by a worm-wheel adjustment and spring 46. A plug cock 50. controls the access of power fluid to the valve which is always slightly open at the ports 37.
