Abstract

151,522. Dewdney, G. F. Feb. 3, 1920. No Patent granted (Sealing fee not paid). Valves.-In a four-stroke-cycle engine having opposing pistons d, e of two diameters in each cylinder a, the two co-axial combustion chambers s, t are controlled respectively by piston valves l, r driven from a half-speed cam shaft o, and having multiple ports co-operating with inlet and cutlet ports m, n respectively in a removable valve casing p.
