Abstract

12,474. Lake, W. E., [Ingersoll-Rand Co.]. May 23. Fluid-actuated gears. - The cylinder is provided at each end with separate inlet and exhaust passages 11, 12, 15, 16 leading to separate inlet and exhaust chambers 4, 5. The admission and exhaust ports 13, 14, 17, 18 are opened and closed by the heads 9, 10 of a valve which is moved at each end of the piston stroke by the compression in the cylinder.
