Abstract
627,381. Cylinders, valves and valve-gear. TWIN COACH CO. July 29, 1947, No. 20486. Convention date, Oct. 2, 1945. [Classes 7 (ii), 7 (iii) and 7 (vi)] In a two-stroke engine cylinder having inlet and exhaust ports 60, 64 at the same level, the exhaust ports are opened and the inlet ports are closed by the piston, but the exhaust ports are closed by a valve 20 and the inlet ports are opened by a valve 22. Rotary valves are shown comprising a hollow inlet valve supplied at one end, and an exhaust valve having a transverse passage and a cam for operating a fuel injector 91. By removing a plate 82 the inlet valve may be replaced by a valve similar to the exhaust valve. The valves are rotated in opposite directions at crankshaft speed by spur gearing at either end of the engine, whereby their direction of rotation may be reversed. Balance weights are provided on the ends of the valve shafts. A crescent-shaped piston head 96 which deflects the charge, enters the clearance space 50, and produces a compact combustion chamber adjacent the fuel injector 91. Cylinder liners are supported on flanges À26 so that the upper parts 28 are exposed to the cooling water flowing to the head jackets by passages 56. They are retained by screwed pins 32 and a space 46 allows for expansion. Specification 615,045 is referred to.
