Abstract

A single stroke engine has a semi-circular combustion chamber 1 in which an oblong shaped piston 3 with flat sides rotatably oscillates. The piston 3 has grooves for location of compression slats or rings 24, and has a circular portion in which a swivel pin 9 is splined and held by grub screws 28. The chamber 1 has two exhaust ports 2 on one side of the chamber 1 and an inlet valve 7 for an air/petrol mixture on the other, and has removable base (11, Fig 4) for access to the piston 3. A spark plug 8 on each side of the chamber ignites the mixture, driving the piston 3 on each stroke. The chamber 1 is bolted onto an oil-filled crank case (21, Figs 6 and 7), and the piston 3 drives an output shaft via the swivel pin 9, through connecting levers (18) and rods (19), crank pins (22) and crank wheels (16).

Description

2337087 1 A ONE STROKE ENGINE.
This invention relates to a one stroke engine.
A one stroke engine has a semi-circular combustion chamber that is bolted onto a common crank case. The combustion chamber itself is basically independant to the crank case except for being linked to connecting rods and levers to the crank wheels.
According to the present invention a one stroke engine explodes on each movement of the piston from side to side.
A specific example of the invention will now be described by way of reference to the accompanying figures related to the drawings.
The combustion chamber 1 has two exhaust ports 2 at one side of the chamber. The other side of chamber has one inlet valve 7 to fit carberetta to mounting pins 10. The base of combustion chamber 11 or piston cap are removed from i. ' he combustion chamber by way of bolts 12 to allow removal of piston 3 from chamber 2 FICTIRE 1 1/8 shows cut away of semi circular combustion chamber with piston in centre position and exhaust valve position. Also showing piston travel 4 and 5.
FIGURE 2 2/8 shows a cut away of combustion chamber with piston on compression stroke 5. Also showing inlet valve position as seen from right hand side.
FIGURE 3 3/8 shows a cut away of combustion chamber with piston on compression stroke 4. Also showing exhaust valves and spark plugs.
FIGURE 4 4/8 shows external view of combustion chamber and lower half of combustion chamber piston cap detached. Showing also position of swivel bearing and circular portion of piston. Also shows inlet valve and carberetta mounting pins.
FIGURE 5 5/8 shows external view of combustion chamber from left hand side with exhaust ports, swivel bearing and also shows cap gasket in position and cap bolts. Also shows head gasket and bolts.
FIGURE 6 6/8 shows cut,.-jay of crank case showing swivel pin lever and connecting rod. Also shown are crank wheel and output shaft wheel, and crank shaft bearing housing as seen from left side, FIGURE 7 7/8 shows cut away view of internals of crank case showing crank pin 22 and connecting lever pin.
FIGURE 8 8/8 shows a piston of a one stroke engine which has groves where compression slats/rings fit. At the circular base of piston shows swivel pin location which is taper splined. is -swivel pin with tapered spline in centre of pin ine on piston. At each end of swivel pin ller tapered splines where connecting shown are two thredded Prub screws Also shown which fits into spl are two slightly sma rod levers fit. Also which fit at each side of circular base of piston that when screwed into place clamp into location holes of swivel pin.
