IDISTRIBUTER FOR INTERNAL-COMBUSTION ENGINES.

To all whom 2'6 may concern:

-Be it known that I, EUGENE Louis Liion MliNAGJi, citizen of the. Republic: of France, and resident of 88 Boulevard de Portdtoyal, Paris, in the said Republic, engineer, have invented certain new and useful Improvements in Distributers for Internal-Combustion Enginesrancl'l dohereby declare the following to he a full, clear, and: exact description ofthe invention, such as will enable. others skilled in the art to which it appertains to. make and use the same, refercncebeing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of" this specification.

The invention relates tointernal combustion engines-in which the valves are reable ports, rotating on a lane surface a manner that the requireddistribution is obtained by the passage of the port or ports pasta fixed port in the end'of the cylinder. Distributers'with rotary" disks of thistype have been used for internal combustion engines, but in these previously known arrangements two fixed ports in the end of the cylinder: were required with the result that the dimensions of these poi-ts we're considerably restricted, and it was generally necessary to form the upper Wall of the explosion chamber of the cylinder with a plane surface. A i 3 According to the present invention only a single port is required in the end of the cylinder which port serves at the same time for the admission and exhaust of the gas, andin the rotary disk there are two inclined ymssages alternately placing this port in communication with the admission and with theexhaust pipes. Since the single port can be placed in the center of the end of the cylinder, this construction permits the use of hemispherical ends, and'of ports of relatively'verylargearea, which improves the working of'the engines. Leakage is pre vented between thedistributing disk and its two contact surfaces by sliding sockets provided with packingrings like a piston and suitably pressed against the disk by means of springs. The system can be very conveniently applied to engines with two. four,

six or more cylinders, by using the same disk to. control two adjacent cylinders.

Tn the accompanying drawings, Figure 1 is a vertical. section of the upper part of a single cylinder engine provided with a rotary disk distributor, according to the invention. Fig. 9 is a plan view of the same, with the covering of the upper casing of the disk removed.

The cylinder (1.. preferably formed with a 'hen'lispheri cal end, has a port Z of large section at the center of the upper end, which port serves at the same time for the admission of the gaseous mixture and for the as cape of the burnt gases. The distributing disk (2, of relatively large depth, 'rotates above this port on' the upper tace'of the cylinder about an axis, which is eccentric to the axis of the cylinder.

The disk 0 has on its lower face two ports (Z and c at the same distance from the center, one for the admission of the explosive mixture and, the other for the escape of the burnt gases. The two ports, which are suitably placed in relation to each other, are continued by inclined passages traversing the disk and leading into corresponding ports (2 and e on its upper surface at diil'erent distances from the center, the port (5 being nearer the center than the port (Z, and the port 0' being nearer the periphery than the, port 0. The upper ports (5 and e of the disk at each revolution communicate respectively with the admission and exhaust tubuluresf and and effect the required distribution in .the cylinder.

Leakage betwem the lower face of the disk 0 and the cylinder is prevented by means of a flanged socket hplaced in the cylinder port Z) having segmental packing pieces on its outer surface and springs j pressing the flange of this socket againstthe lower face. of the disk (2. In the same way leakage is prevented at the upper surface of the disk by a double socket it with packing pieces '21 and flanges which press by means of the springs j on-thc upper face of the disk 0.

The disk is pivoted. in ball bearings 7c and the upper" face of the disk rests against an annular hall race 2 to reduce the friction and to take the thrust on the disk due to the explosion. In order to lessen the pressure br'ng partly exerted on the upper ball bearings k and Z.

Similarly the lower edge of the socket k may also be beveled at n to -facilitate the passage of the gas.

The distributing disk is driven by a toothed wheel 0 gearing with teeth c'on the disk and fixed on a vertical spindle p driven by the distributing shaft of the engine. The diameter of the toothed wheel 0 mayadvan- 'tageous'ly be half that'of the disk, so that to obtain the required distribution, the open ings d and e of the disk should be 90 apart and separated by a plain portion equal to the diameter of the port I) of the cylinder, as

shown in Fig. 2. Also the ports'should be. preferably in the form of. sectors, with curved edges, so as to obtain atthe same time an abrupt closing and the greatest duration of opening. In an engine with. 2, 4;.

or more cylinders, .the same disk can'control the distribution of two adjacent cylinders and these disks can be geared together and "actuated by a single pinion, either at the center'or at one end of the engine. Since the upper ports (2 and e of the'disk c are not at the same distance from the axis,as

the lower ports (1 and e and are on difierof the upper face of the disk,

ent diameters they will have different peripheral velocities: so that to'avoid resistance to the flow of the gas, the cross section of the port, in

. which the velocity is greater, in-this case the exhaust port '6, should be correspondingly increasedas shown in Fig. 2. v

The admission andexhaust 'tubulures, f

and a should preferably be formed, as shown in Fig. 1, in a projecting part of the cover a of the casing. in which the distributing disk and'its driving gear 0 are placed. This projection of the cover can also be advantageously used to form a water chamber 1' around the tubulures' f and ,.whi'ch keeps the disk cool and is in communication by.

means of suitable passages with the cylinderwater jacket 7-; cooling water can be admitted through a. tubnlure s at the top of this chamber. Since the disk must necessarily have considerable depth, on account of the inclination of the passages traversing p it, a should preferably be hollow, and this also will help to prevent its being over heated.
