Abstract

177,115. Carruthers & Co., Ltd., J. H., Gourlay, J., Johnstone, G. K., and, Young, J. Sept. 7, 1921. Linkage gears; slide valves, flat. - In a duplex pump, each valve is arranged to control the admission and exhaust in the adjacent cylinder and the cut-off in its own cylinder. The valves are made in two parts 2, 2, 8, 8 connected to common rods which are operated by the pistons of the corresponding cylinders. The valve 2, 2, operated through lever mechanism 4, 5, 6 from the rod 3, moves in the same direction as the corresponding piston; the valve 8, 8 moves oppositely to its piston. The upper part of the valve 2 is arranged between the upper part of the valve 8 and the ported seat 1; the lower part of the valve 8 is similarly arranged with respect to the lower part of the valve 2 and seat 1.
