SHEET l [1F 4 AXIAL CYLINDER ROTARY ENGINE BACKGROUND OF THE INVENTION Various axial cylinder engines are known which comprise two main types, viz, engines having a stationary cylinder block and engines having a rotary cylinder block. It has been proposed to use in the last mentioned type a stationary crankshaft together with a specific crank mechanism comprising rocker arms each of which is common for two cylinders. It has further been proposed to use a rotary crankshaft which is driven by a swash plate or a sloping plate. These prior known engines have been designed with various objects in mind but the proposed solutions have generally rather complicated.
SUMMARY OF THE INVENTION The present invention relates to a four-cycle engine with rotating, axial cylinders. Engines of this type have been designed with various objects in mind. The object of the present invention is to produce an engine with a simple rotation slide distributor or valve system. This object is quite new and it is realized by a substantially plain slide distributor surface between the cylinder group and a stationary gable and by keeping the sliding speed low by means of different and reduced speed of the cylinder group in relation to the swash plate driven crankshaft.
Furthermore the engine according to this invention has an other unique feature in the referred class of engines having the ignition devices in the stationary gable. Among other advantages this feature gives the possibility of using a continuously or periodically acting ignitor which makes possible the use of slower igniting fuels.
The simplicity of the design makes it particularly attractive in a small size engine. These can be economically made with three or more cylinders, which with the fully balanced transmission mechanism ensures a reliable and extremely smooth running. A simple planetary or two plane gear used for determining the speed ratio and can simultaneously be used for speed reduction from crankshaft to a separate output shaft. This output shaft can alternatively consist of the axle on the slowly running cylinder group.
SHORT DESCRIPTION OF THE DRAWING FIG. 1 is a sectional view of an engine with five cylinders and two sequences per cylinder group revolution according to the invention.
FIG. 2 is a section at the plane 11-11 in FIG. 1 showing the slide distributor surface.
FIG. 3 is a schematic illustration of the working mode of the engine according to FIG. 1.
FIG. 4 shows the planetary gear modified for contrarotating cylinder group and crankshaft for threeor seven-cylinder design.
FIG. 5 is a liquid cooled embodiment of a five-cylinder engine with a combined reduction and distributing gear.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 the stationary engine frame consist of mantle 11 and gables l and 12. In the gable 12 there is a bearing 13 for a crankshaft 3. A cylinder group 2 runs on bearings 15 in the gable l and 16 on the crankshaft 3 respectively of which the inner end runs in a bearing 14 in the cylinder group 2. Thus the crankshaft 3 and the cylinder group can rotate separately and their rotational speed and direction is deter mined by a planetary gear consisting of a sun wheel on the crankshaft 3, planetary wheels 9 on the crankcase end of the cylinder group whilst the outer wheel 8 is fixed to the engine frame 11 and 12. In this case (five cylinders) the crankshaft 3 and cylinder group 2 are rotating in same direction. With Z teeth on the sun wheel 10 and 4 X Z teeth in the outer wheel 8 the speed relation between crankshaft and cylinder group is as five to one. The speed difference is thus four, i.e., the crankshaft makes four revolutions in relation to the cylinder group during one revolution of the latter in the stationary frame and against the slide distributor surface 5.
In this way two complete four-cycle sequences are efi'ected in one cylinder as described more in detail below. A swash plate 4 on the crankshaft 3 gives via connecting rods 16 the necessary reciprocating movement for pistons 6. As embodied in the FIG. 1 the rotational movement of the swash plate is coupled to the cylinder group by means of a ring 7 which is carried by two opposite bearings in the crankcase part of the cylinder group and connected to the swash plate by one or two swiveling pins (not shown in the figure) at -angle to said bearings. Alternatively the syncronization can be effected by, e.g., a pair of matching bevel gear rings.
The channels 5 in each cylinder 6 are sealed against the slide distributor surface in gable 1 by means of whatever known sealing arrangement. Thus this seal can be, e.g., a tube ring or plate made of metal or plastic material. In the gable 1 there are ports 20 for intake of fuel and air (the port 20 is in the sectional upper part of FIG. 1 not visible) and ports 21 for exhaust. The gas distribution is effected by the slide valve action arising from the rotary motion of the cylinder group 2 where the ports 5 pass the openings for ports 20 and 21 in the slide distributor surface.
The ignition is effected by igniting devices at two diametrically located sites 18.
The operation of the engine according to the invention can be described with the air of section IIII from FIG. 1 as shown in the FIG. 2, i.e., against the slide distributor surface in the gable 1.
Due to the rotation of the cylinder group 2 each cylinder 6 and its port 5 are successively passing four zones in the gable 1 during one complete four-cycle sequence. These zones are marked by I, II, III, and IV in FIG. 2 and their divisions is given by radial dotted lines. There are two sets of such zones each covering in the figure The locations of the cylinders are marked by dashed circles and ordinal numbers 6 -6 When the cylinder group is rotating clockwise, e.g., the cylinder 6 passes at first the zone I which is an intake zone with opening to the intake port 2 and thereafter the zone Il during compression cycle whereby the port 5 runs against a closed face. At the end of zone II the one ignition device 18 initiates the working cycle in zone III.
The cylinder then passes an exhaust opening in 21 in the zone IV thus completing one four cycle sequence. The same functions are then repeated during the second half turn back to the initial position.
The diagram in FIG. 3 is a schematic illustration of the movement of piston 6 between top (TDP) and bottom dead point (BDP) during a full 360 revolution of the cylinder group. The figure also shows the initial locations of the other cylinders 6 -6 In an engine thus described the gas distribution is effected through the movement of the cylinder group in relation to the gable 1. An extremely simple and reliable distributor action is obtained without valves and practically no additional parts. Due to the reduced speed at the cylinder group which is onefourth or less of the effective speed of the crankshaft good sealing and wearing properties are obtained as well as moderate frictional less in the slide surface.
FIG. 4 shows a detail of a different arrangement of the gear suitable for, e.g., three or seven cylinder embodiment of the invention with contrarotating crankshaft and cylinder group. For the function described above with two working cycles (ignitions) per cylinder group revolution in this embodiment the speed relation shall be as 3:1 between the crankshaft and cylinder group. This is obtained by means of a planetary gear where the outer wheel 8 is mounted on the cylinder group 2 crankcase part and the planet wheels 9 are running on bearings fixed to the stationary gable 12. For Z teeth in the sun wheel 10 the outer wheel shall have 32 teeth. In other respects the operation of this embodiment is equal to that of the described engine according to the FIGS. 1 to 3.
The other parts as fuel, ignition, and lubricating systems can be of conventional type and are therefore not described here. As, however, the ignition timing can be determined by the position of ignition device in the distribution surface this device can be of continuously or periodically acting type as, e.g., a glow-plug. This allows for the use of a wide variety of fuels. Similarly the fixed position for other strokes gives the possibility of using the compression for, e.g., fuel injection. Air or gas starting is also possible without complicated valve arrangements.
Alternative cooling systems with air, water, oil, or other fluids can be used. A combination of air and liquid cooling is indicated in F IG. 1 with fluid cooling space 22, 23 in the gable l and in the mantle 11 respectively. FIG. shows an altemative with fluid cooling through ports in the slow running shaft 19 fixed to the cylinder block. The cooling agent is taken into the shaft via a casing 31 fixed to the gable l. Fluid from and to cooler is conducted via ports 29 and 30 to two toroidal chambers 35 and 36 which again communicate directly with ports in the axle 19 and thus with the cooling space 37 in the cylinder block. Alternatively the stub 30 may be placed on the gable l in order to direct the cooling agent directly from the chamber 32 inside the casing 31 into the cooling space 22 in the gable l or vice versa. The chambers 35 and 36 are sealed mutually by the seal 33, outward by seal 34 and towards the lubricated bearing by a double seal 32.
The right hand side of FIG. 5 illustrates a possible arrangement of cylindrical or helical gear consisting of a primary transmission 10-25 to an output shaft 24 and a secondary gear 26-27. Alternatively the output can be taken via a gear wheel 28 in the secondary gear 26-27. The wheel 27 is fixed to the crankcase part of the cylinder group 2 thus determining the speed ratio between the cylinder group 2 and crankshaft 3. This gear arrangement is suitable for, e.g., five cylinders (with two ignitions per revolutions) or seven cylinders (with three ignitions per revolution) embodiments.
in the FIG. 5 there are shown two carburators 38 which in an practical application will be placed in a horizontal plane,
Le, in a plane in right angle to the sectional plane of the gear of the FIG. 5.
