a To all whom it may concern:

Be' it known that I, CHARLES EDOUARD ,HnNRIon, a citizen of the Republic of Val'veless Motor, of which the following is a specificatiom The four-phase, val'veless motor, to which the present patent relates, is characterized by the combination of channels cutin the piston itself, with other channels or grooves cut 'in an outer rotating part, in such a manner as to isolate the bottom of the cylinder during the compression and explosion phases, to bring it into communication with the carburetor only during the admission phase, and with the atmosphere only during the exhaust phase. To this end, the herein illustrated arrangement in which the piston undergoes during its stroke a rotary move ment around its axis (Fig. 1), and a modification in Which this movement is dispensed with.

In the annexed drawings: Figure 1 is a vertical central sectional view of one form of the motor, showing the piston at the end of the stroke. Fig. 2 I, is a similar view showing the piston at the commencement of the stroke. 'Fig. 3 shows a horizontal section taken on the line A-AB Fig". 1., Fig. 4

shows a horizontal section taken on the line CD, Fig. 1. Fig. 5 shows a vertical section of another modification with the piston at the end of the stroke.

Referring to Figs. 1 to 4, 1 designates the cylinder; 2, piston; 3, driving crank; 4.

piston rod; 5, one of the grooves of the part 1 6; 6, another groove cut in 16; 7, inlet pipe;

8, extension of the piston provided with a groove; 9, communication channel between 7 and 14; 10 opening in the cylinder; 11,

'sparker; 12, outlet for the spent gases; 13,

peg actuated by 5; 14, channel cut in the piston; 15 exhaustchannel; 16,distributer or device for controlling the inlet of as.

In the preferred arrangement shown in the drawings,) the piston 2 has an extension 8 provided with a groove into which engages a pe 1 3 actuated by the special groove 5 the unction of which groove 5 is to move the peg 13 slightly from right to left, or vice versa, so as to give the plston a slightly rotary movement around its axis, the efiect of which is to produce or to prevent commuing this phase,

nication of the channel 1 1 with 9.and of channels 15 with openings 12. The piston 2 is, in fact, provided with one or more channels 15 which can be brought in front of openings 12. We denominate as openings 12 those chosen from among the openings 10 made in the cylinder expressly to correspond with channels 15 The channel 9 may be brought into communication with the channel 7 (inlet of the gaseous mixture) which rotates at half the speedof that of the shaft of the motor, is driven direct-1y by a set of gearing havinga relation of 1 to 2.

The form of groove 5 is so out

thatcommunicationbetween

12 and 15 is .only established during the exhaust phase. To this end. The operation of this form of the invention is therefore as follows: Duringthe entire phase of aspiration (1st phase), the piston descending, the groove 6 is open, that is to say it allows free communication between 7 and 9, and the groove 5 has given to the piston a position which allows 14 to communicate with 9. On reaching the end of the stroke (Fig. 1) the groove 6 has con tinued its movement, as well as groove 5: communication between 7 and 9 is closed. The piston is about to rise again to effect the compression (2nd phase), the grooves 5 and 6 continuing their rotary movement. Durcommunication remains closed between 7 and 9. The sparking takes place at this moment, and the explosion is produced (3rd phase), during which 7, 9

and 14 retain the same position as during the compression. Finally, the piston, in its upward movement, forces the spent gases to escape (4th phase). It will have been clearly understood that the spent gases commence to escape when, at the end of the third phase (explosion), the openings 10 are 15, which is or are placed in communication with openings 12 by means of groove 5, which has caused the piston to rotate. During this time, the groove 6 has continued its rotation, but has not yet openedup communication between 7 and 9. This communication will only be established during the succeeding phase, that is to say during the first phase of the second cycle, and the operations continue in the same order, communication' between 7 and 9 only being established once (aspiration) during the entire duration of a cycle.

Operation: 1st phase (suction): 6 places in communication 7 and 14, i. e. the carbureter' with the bottom of the cylinder. 2nd phase (compression). For these two phases, 6 has rotated and 3rd phase (explosion) the part 16 completely obstructs the channel 9. 41th phase (exhaustion). The part 16- presents the groove6 in such a position that the channel 14 is brought into communication with 15 and 1 2.

I claim: 1. In a four cycle explosion motor, the combination with a cylinder provided with orifices capable of communicating with the exterior either for the admission of fresh gases or for the expulsion of burned gases, a rotary sliding piston, having channels for establishing communication with said orifices, according to the position of said pis: ton, a rotary distributer adapted toadmit gas into said cylinder through one of said piston channels and one of said orifices dur-.

communication is cut off between the carbureter and the interior of thecylinder during the compression and explosionperiods. In testimony whereof I atfix my signature in presence of two witnesses.
