Abstract

134,759. Homersham, T. H. C. April 22, 1919. Slide valves, cylindrical and piston.-In order to control the supply of steam to the cylinder, the end V<2> of the valve which takes steam at the centre P is provided with a tapering portion V<3> and then a parallel portion V<4>. Should the valve exhaust at the centre, the parts V<3>, V<4> are provided on the bottom of the piston head V<2>.
