ROTARY VALVE.

Specification of Let ers Patent.

Patented Feb. 3,1914.

Applicadon filed April 7. 191'; Serial No. 759,578.

To all whom it may comm-11.:

Be it known that I, Itnxti (itIiLIJ-JRY, a citizen of the. French lepublic. residing at 103 Avenue de la Republique, Auberrillicrs, Seine in the French Republic, have invented certain new and useful Improvements in Itotary Valves, of which the following is a specification.

The present invention relates to a dis tributing system for internal combustion enchamber and which'comprises therein ports which register with the admission and exhaust orifices at theproper times in the driving cycle.

In order to insure the tightness and also to prevent the pressures (of compression or of the explosion of the gaseous mixture) exerted on the distributor from retarding the sliding of the distributor on the walls of the cylinder which serve as a valve seat the mechanism which controls it is such that it maintains the contact: friction between the valve and its seat constant. To this end,

the mechanism connecting the distributor to the controlling member '\\'lil(fl1 transmits to it a continuous movement of rotation about its axis, is arranged in such a manner that if the contact motion on the walls increases there is a relative angular displacement of the driving and driven members. In consequence thereof and by means of. a suitable mechanical system, the disphn-ement referred to is transformed into a longitudinal displacenn-mt of corres 'iomting amplitude and which, by unscating the distributor. rc-

duces the friction to its normal vahi'c: The

' members then return to their original posisitions which permits of driving without any angular displacement the tightness ot the distributor being then assurot'l owing to the friction existing between the latter and the walls ot the cylinder on vthirh it slides.

The inc-arm, to which the present .int'ention relates porn'iit also of obtaining the above the system may be.

ivliatcver the. direrti n of rotation' of example: Figure In the accompanying drawing and by way 1 is a vertical section of the upper part of a cylinder of a motor comprising a conical distributer to which are applied the controlling devices embodying the invention. Figs. 2 and 3 showin plan two ditl'erent, forms of bearing plates which may be combined with balls so as to form running grooves for them. Figs. 4; and 5 are developed views of the bearing plates (Figs. 2, 3) showing their relative a-rrangement and their combination with balls and controlling springs.

The cylinder a ends in a chamber 12 of conical form the walls of which constitute the cylinder. Passages 0, (Z for the admission of the explosive mixture. and the exhaust of the burnt gases to and from the cylinder leadthrough the wall of .the chamber b. The conical chamber 0 receives a hollow distributor e, the wall of which is provided with one or more ports f, and controls the admission and exhaust orifices when it is rotated on its axis. To this end, the distributor e is provided with a vertical spindle g which passes through the cylinder end a; a plate It is fixed on said shaft and its horizontal surface is provided with grooves it of different pitch, constituted by any number of cavities either spherical Figs. 34)), the radius of which would then be greater than that of the balls -i it receives, or oval (Fig. 2). In Fig. 5 the interposed balls '1'. are shown arranged within similar cavities It of another plate j which is arranged above and parallel to the plate 71. keyed on the shaft of the distributor. e. In Fig. lthe plat j is shown provided with raised surfaces It which co-act with the balls i. The arrangement shown in Fig. 4 is suitable 't'or engines which always rotate in the same direction. while the arrangemrn't shown in Fig 5 can be applied to engines which rotate in both directions. This plate j is loosely mounted on. the extension 7.: forming a socket for the cup shaped nut in which closes the chamber It situated above the cylinder u. and receiving the whole of the controlling nteclninism. A ball bearing disk I pormitsot' the rotation of the plate j on the correspmuling face of the nut m but opposes the longitudinal displacement; of said plate. The shaft y of the distributor 0 passes freely through the extension A: and is subjected to the action of springs 1 which may be Belleville washers or of any other suitable kind arranged on the exterior of.

the motor and within the cup formed by the nut in. The spring p rests, on one hand, on a washer q and aunt 1' of the shaft 9 of the distributer. e, and, on v the other hand, it rests on a ball bearing disk 8 pressing on the bottom of the nut m which closes the chamber a receiving the controlling members; in this manner it is possible by screwing more or less the nut 'r on the shaft 9 of the distributer e to regulate the tension of the spring 79 which presses said distributer on the wall of the corresponding conical cham-' ber 72' and determines the friction which insures the tightness of surfaces in contact. The motion is transmitted inany suitable manner from the driving" shaft or secondary shaft to the engine to a shaft t provided with a worm u, keyed thereon and engaging with the teeth cut on the plate flange j. The plates h, j, separated by balls 2' which are located and can mbve within suitable cavities h h" provided for this purpose, are, moreover, connected by springs 41 which exert a controlling pressure on the parts when angularly displaced. In Fig. 4:, for example,

,coiled. springs 11: are provided, the ends of which are fixed to ribs in of the plates h, integral 'with the distributerc and the controlling member, respectively. These springs cact' in tension which is regulated for the friction-which, in order to maintain tightness must be of a. sul'licient degree between the distributer and its seat, gives rise to a resisting couple balanced by the couple of said springs o. r

in the modification Fig. fiiblade springs a have been provided, which are held in position by their ends fitting in between theconjngated faces of the plates h, These springs act in a manner exactly like the SPIIYIQ'SU and,moreover, in \VlliltGVBRdlIBG- tion the driving shaft and the distributer e may be. rotating. It will be seen that, nor mally, the distributer 0 being pressed on'its scat owingto the spring 1' suitably regulated" to this end, is driven by the controlling system; the whole of it rotates without any angular displacement as if the transmission were but one element. when thercsistance to the displacement increases, which is due to the friction of the distributor c on its seat increasing the said distributer tends to retard the driving mechanism which continues to be actuated. The latter acts on the distributer e by means of its faces It inclined relatively to the faces 71. and the interposed balls 11 so as to free the said (llStlll'llltOl flfim its seat b and to diminish the friction between these members. As soon as the friction diminishes, the springs r \vhiclrhave been in tension owing to the angular displacement of the plate 1, 7', of the distributer e and its driv- On the contrary, I

ing mechanism, respectively, act on said members in such a manner as to return them to their original position. In consequence thereof, the friction falls to its initial value which is sufficient to maintain tightness but insufficient to produce the seizure of the contacting slidingsurfaces.

The arrangement of the inclined surfaces of varying p tch h, h of the plates h, j between the conjugated faces of which balls i are interposed, permits of var ing the amplitude of the longitudinal disp acement of the distributer e relatively to its seat b, more rapidly than the an les of the an la r displacement between t e said distri uter'and its driving mechanism. In these circumstances, if an angular displacement of the distributer e relatively to its drivin mechanism gives rise to a certain longitu lnal dis and tightness.

lVhat I claim as my invention and desire to secure by Letter Itatent of the United States is i 1. An internal combustion engine comprising a cylinder having a conical chamber at one end, orifices in the wall of said chamber to admit the supply and exhaust of the motive fluid, a hollow and conical distributer in said chamber and sliding on the wall of the latter, orifices in the distributer to control the admission and exhaust ports, a vertical shaft extending from the distributer and having athreaded end,a chamber situated' above the distributer, and which receives the driving mechanism of the dis tributer, a cup shaped nut for closing said chambcr, a hollow boss in the center of said nnt projecting within said chamber b then it will be found that a doubleion and through which passes the shaft of the distributer, a nut adjustably mounted on said shaft, a spring pressing against said nut, which can be shifted on the threaded end of the distributer shaft and against a ball bearing disk at the bottom of the up shaped nut, means for rotating said istrihnter and maintaining the friction constant between the-distributer and its seat.

2. In an internal combustion engine, a cylinder, the end of which constitutes a conical chamber, orifices in the wall of said chamber for the admissionand exhaust of the motive fluid, a hollow conical distributer in said chamber and which has sliding contact With the wall of the latter, orifices in the distributer for controlling the admission and eX- hanst orifices, a vertical shaft extending from the distrihnter beyond the distributer and threaded at its upper end, a cup shaped nut supporting said distributer, a hollow boss in the center of said nut and through which passes the shaft of the distributer, a

spring pressing against a nut provided on the upper end of the distributor shaft, and
