Abstract

419,258. Four stroke engines; oil engines. MILLER, J., and REBBECK, F. E., c/o Harland & Wolff, Ltd., Belfast. May 1, 1934, No. 13075. [Classes 7 (ii) and 7 (iii).] In an engine having a hollow piston compressing the air charge at its rear side, the compressed charge is admitted to the combustion chamber through a valve 8 seating in the crown of the piston. The exhaust valve 4, or the fuel valve, or starting-air valve, or ignition device, is disposed in the cylinder head in an opening 6, through which access may be had to the valve 8. The hollow piston forms an air reservoir 14 which may extend down into a space 15 in the piston rod. The reservoir 14 communicates by a check valve 22 with the closed end 19 of the cylinder, the latter having one or more suction valves 21. The valve 8 remains closed during the firing stroke, air behind the piston being forced through the valve 22 into the hollow piston. Towards the end of the exhaust stroke, as the cylinder pressure falls, the air pressure within the piston opens the inlet valve 8, which remains open during the suction stroke, further air being forced into the hollow piston. The valve 8 may be automatic or actuated mechanically, either by an extension through the piston rod, or by mechanism extending through the side or bottom of the piston. The various hollow pistons may be connected together by telescopic pipes working in fixed vertical pipes connected to a horizontal manifold.
