Definitions
- AXIAL SHAFT PISTON ENGINE This invention relates to a mechanism which may be used as an internal combusion piston engine or positive displacement piston pump or compressor -in which the output shaft is co-axial with the pistons and in which the reciprocating movement of the pistons is transformed into rotational movement of the shaft (and vice versa) by means of one or more cylinder cams mounted on the shaft and acting with rollers attached to the pistons.
- the objects of this invention are to reduce physical size for a given capacity, simplify the manufacture of the major structural parts, reduce the number of parts, simplify the balancing of reciprocating masses, and increase mechanical efficiency.
- the objects of this invention are achieved by arranging the pistons and shaft co-axially, with the shaft running through the centre of the pistons.
- the pistons and cylinders are arranged such that the pistons move inwards and outwards in their cylinders concurrently under the effects of the gas pressures in the combustion chambers and act, via rollers mounted in a yoke attached to extensions of the pistons, on the cylinder cam which is mounted on, and forms part of, the axial output shaft. This in turn produces torque in the shaft.
- FIGURES 1A, IB & 1 C show the mechanism as an internal combustion engine (see also schematic diagrams FIG 2 & 3).
- a shaft (9) runs axially through the centres of the end caps and the pistons and carries a specially shaped cylinder cam (10) at its centre.
- the cam (10) is straddled by double rollers (11)(12) & (1-0(13) (FIG IB) which are mounted in yokes (2 ) & (25) attached to an extension of each piston (1) & (2), thus causing the pistons to reciprocate longtitudinally as the shaft (9) and cam (10) rotate.
- FIGURES 2 & 3 are schematic representations of the mechanism.
- the fuel air mixture enters, via a carburettor and valve (16) FIG 2, into the 50 space (15) formed by the pistons around the cam as the pistons move outward. Movement of the pistons inward due to the further rotation of the cam results in the valve (16) closing and the fuel air mixtures starts to compress in space (15).
- the induction port (17) is uncovered by the pistons and the pressurised charge transfers from the space (15), via the transfer ports (18) into the combustion chambers (7) _c (8).
- the spark plug (20) ignites the fuel thus causing a gO pressure build up in the combustion chambers (7) & (8) and the pistons to be forced inwards. This imparts a force to the cam (10) via the rollers (11) & (13) and causes the cam to rotate and impart torgue to the shaft (9).
- Torque reaction on the pistons (1) & (2) is opposed by flat linear roller bearings (27) acting between the piston yokes (24) & (25) FIGURE ⁇ forming part of the piston extension, and the centre section engine casing, (26) FIG 4.
- FIG 6. shows a four lobe cylinder cam which will give two inward and two outward strokes of the pistons (1) & (2) per revolution when mounted on th shaft (9) in place of the two lobe cam - FIG 5. This will provide two power
- FIGURE 7 depicts one end i.e. one pumping chamber for simplicity.
- the shaft (9) When the shaft (9) is turned by external means, the cylinder cam (10) rotates and causes the psitons (1) & (2), by means of the rollers (12) & (14), to move inwards and draw fluid (gaseous or liquid) through the valve (21) into the annular space (7). Further rotation of the shaft (9) causes the pistons (1) & (2) 90 by means of the rollers (11) & (13) to move inwards and force the fluid from the space (7) out of the valve (22).
- a further application of this configuration would have one chamber used as an internal combustion power producing piston engine (as in FIG 3) and the other chamber used as a pump.

Abstract
Dans un mécanisme pouvant être utilisé comme moteur à combustion interne, comme une pompe ou comme un compresseur volumétrique à pistons, l'arbre secondaire (9) est co-axial par rapport aux pistons (1, 2) et passe longitudinalement par le centre des pistons (1, 2). Le mouvement alternatif des pitons (1, 2) est transformé en un mouvement rotatif de l'arbre (9), et vice-versa, par une came cylindrique (10) montée sur l'arbre (9) et par des cylindres (11, 12, 13, 14) fixés à des protubérances de limitation du couple (24, 25) des pistons (1, 2). Lorsque les pistons (1, 2) sont poussés le long de cylindres opposés respectifs (3, 4) par la pression d'un gaz, les cylindres (11, 12, 13, 14) montés dans les protubérences (24, 25) agissent sur la came cylindrique (10), exerçent un couple sur la came (10) et provoquent ainsi la rotation de l'arbre (9). Inversement, dans la construction de pompage, un couple appliqué sur l'arbre (9) par des dispositifs extérieurs provoque le mouvement alternatif des pistons (1, 2) dans les cylindres (3, 4) et permet au mécanisme de fonctionner comme pompe, à l'aide d'un agencement de soupapes approprié.
