To all whom it may concern:-

i Be it known that I, HANs GRADE, e subjeot of the King of Prussia, residing at Mugdeburg, German Empire, have 'invei'lted certain new and useful improvements in Explosive-Engines and 1 do hereby deelare the following to be zi'luli, clear. end'exset description of the invention, such as will enable others skilled in the art to which it upper-talus to make and use the some, reference being had by means of an inlet value, which at the slime time lets pass or forms this charge mixture .and serves also when using liquid fuel as a means for heating this fuel in a preliminary manner and volatilizing it.

Referring to the drawing in which like parts are similarly designs-ted, Figure l is a vertical longitudinal section of a motor showing the inlet valve embodying my invention attached. Fig. 2 is a vertical longitudinal section of another form of the inlet valve embodying my invention. Fig. 3 is it front view of the inlet .valve seat in Fig. 2 i

The inlet valve Fig. 1 is shown in connection with a two-stroke cycle motor designed for using a aseous combustible. The cylinder or con'fbustion chamber 10 is provided with an inlet port 11, for the mixture of air and gas and an exhaust port 12 controlled by the piston 18 through which port the products of combustion are expelled.

Below the eylinder i0 is the closed crank chamber 13 having besrhum 14 for the crank shaft 15thet is connected by the piston rod 17 to the piston 18 in any suitable manner.

Between the cylinder 10 and the crank case 13 that acts us 11 pump ehznnber, is a by pass 19 end in the side of this passage '19 is placed the seat for the inletelve.

The pipe 21. for eombustible mixture terininetes and is contro led by substantially he lower half of the inlet veive'23 as s r we and ad acent the pump chamber 35% that the upper part of the valve vill control the passage of sir through its fit) this hen I exposed at. the part 22 to the outer air, so that when the valve opened the outer air will through substantially the upper part 22 of the valve seat through the inletport 11 into the cylinder. The valve 23 is normally held to its seat 20 by rue-ans or sprin 2 4 in the usual in annex.

in. the modification shown in Figs. 2 end 3 the mixture is produced by the inlet valve itself. The inlet valve consists of easing or seat a mounted on the cylinder 3 and of 2 plate or disk 0. The seat a hsis'e centrel opening 1 forming a channel for supplying an and is provided with e spider 4 cerryin a guide sleeve 5 for the stem of the valve dies 0.

This seat has also an annular channel I) closed at its inner side by a ring adapted and soldered to the sent a. The disk 0 is provided with a stem 7 having mounted on it e washer 8 and between this washer 8 and the spider 4 a spring 9 is arranged pressing the vslve disk 0 against the seat a. (ipenings or nozzles e extend from the channel 1 to the seat surfers. For liquid fuel these openings (1 ere a-rrengeil in a small number (for example 2-- l) and smaller, and for gas they are arranged in. a.

greater number (for example 7-10) and broader. These openings are provided. only in the under half of the valve seat, which under half is arranged towards th erenlr chamber, end are closed by the itself, being possible owing to the smell displacing pressure, as it takes place in other construotions in a similar manner i1 using a speeisl fuel valve situated before inlet valve. The luelis supplied to the annulsr channel l) through a thresded inlot pipe e. The operation of form shown in fig. l is as follows: By the upward movement the piston the inlet vs-lve 23 is automatic-ally opened by reason suction action of the piston and through the upper of its seat air is drawn into the bypass 19 and through the 10*. er pert combustible mixture and 00th are conducted through 19 into the srunh ease i 3. As soo n as the piston is driven downwards by the ignition o'irthe gases, the inlet-valve 23 closes end the sir and gas mixture in the creui: case are compressed. Then when the piston 18 uncovers the inletqiort 11 the compressed in. 13 and 19 are driven into the eylind 0. Since ou'ring the un stroke of the pis l tislly onl the lower hull of the valve an only through o unpn: in there is d i the upward travel or the p n-stun queen;-

dist:

ter the cy air in the upper part of the by-pass 19 which when the piston 18 uncovers port 11 will enof the channel 1 released by the valve disk 0 into the passage f] and fills the upper space. On the under hal on the contrary, either the finished mixture enters or the entering air sucks the fuel from the openings at and mixes with it, Whereat liquid fuel is heated in a pre liminary manner at the same time in the annular channel 1). Therefore the usual noninflammable isolating layer drawn through the upper half of the opening of the inlet valve is placed between the exhaust gases of the preceding explosion and the new mixture. 'With regard to the other engines, the separating layer is produced by auxiliary channels, special valves or mixture chambers etc, but in my inver. tion the separating layer is produced by the arrangement of the valve on. the passage leading to the cylinder and by supplying themixture or the fuel from one half of the valve.

Having thus described my invention, what I claim as new therein and desire to secure by v I Letters Patent, is

' l. in a two-stroke cycle ex losion engine the combination with the comli berand the crank chamber of a by-pass connecting them, a valve in said by-pass and means to admit air from the valve to said byass and combustible from substantially one all" of this valve nearest the crank chamber to said by-pass, substantially as described. 2. In'a two-stroke cycle ex losion engine the combination with the combustion chaminder first and form a separating layer between the spent gases and the new ustion chamher and crank chamber of a by pass'connect ing them, a valve and valve seat in the side of said by-pass, means to admit air through the valve and fuel admission ports in a por tion of the seat adjacent the crankchamber as described.

3. In a two-stroke cycle-ex losion engine the combination with the com ustion cham- /ber and the crank chamber acting as a pump means to permit the"passagc of air throu h the valve, an annular chanhel formed in valve seat, fuel out-let-ppenings from said passage through the seat over substantially only one-half the circumference thereof nearest' the crank chamber, said openings controlled by the valve.

4. In a two-stroke cycle explosion engine the combination with the combustion cham her having inlet and exhaust ports controlled by the piston and a crank chamber of a bypass extending from the inlet port to the crank chamber, a valve admitting both combustible and air to said by-pass, the combustible being admitted through substan: tially one-half of the valve nearest the crank chamber.

5. In a two-stroke cycle explosion engine,- t'he combination with the combustion and the crank chambers; of a by-pass connecting them, a valve and a valve seat in. said bypass, means to supply both air and combustible to different portions of the valve and said valve controlling both the admission of air and combustible, the combustible being admitted through that ortion of the valve nearest the crank cham er.

'In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
