Abstract

106,451. Rayner, G. H. T. Feb. 26, 1917. Pistons, main, acting as sole valves.-The distribution of fluid is effected by the main piston x which is provided with a cylindrical interior having a shoulder w sliding over a fixed piston b provided with a central supply passage c and exterior grooves d along with fluid passes to the annular piston surface until cut-off by the shoulder. When the piston, during its outward stroke, puts the port h into communication with the recess j and the left-hand end of the cylinder into communication with the exhaust outlet g, the piston is reversed. The exhaust from the forward end of the cylinder takes place initially through the port e and an auxiliary port e<2>, and finally through the port e and annular recesses f, g.
