This invention relates to an inieinai sombnsition vapor motor or gas engine WhiPi! derives its power from the igniting oi a compressed charge of air and fuel.

For the purpose of iiinstx'aiion, however,

The synchronous communication between said rotary viiive end said force T ibis construction the glue pump may lee (lenouiinuecl broeliy as the action of acct-off vvelvc. Said chenil'fser e o tends anuulerly completely er xc the our gine cylinder so YJhat tiie'ges which is reteincd in said cherub-cu for a "cut pei-ioil of fiime heated by, Queen h s contact with the cylinder. W ll flute zloe is thoroughly vaporize bytlie combined simultaneous act-ion of both like local the pressure. This measuriiig chumboi opens into engine 'cylinclec'tlirough the aforementioned. feeding vapor port 18 which is locetecl oreflie sicl-e of line engine which is opposite to the valve 3901*533 through which the gas cuEL-ei's said measuring chamber. Thus the peusielly vaporized or vapor which enters the measuring chamber is ceusedto pass completely crowed the heated engine cylinder beioi'e being vemed into the iutexior of said cylimler' timough the leech ing port 18 when the some is uncovered by iglic descendizcg piston.

The exa-ict-lzimmg or the rotary valve 31 may i varied considerably according to 'elnc requi weenieo' iiie engine amlaccordmg to the z rgoe of the ei ginc, and the valve itself of suitable type oir mechanically The suicl valve 81 may be 'l to ogpen at any point in the cperaiion subsequent to the rising top of piston above the top eclge feecliiig port 1%. The closing of said fi i illiy occur at any cifme prior to. the un g; of said ieecliug port 18 by the depiston Eu'l; in any case it is doi the valve timing be such that the ve is closed Whenever the feeding is opened.

In speed of mm {1.54m of said valve 310 hail-f lllilii) of the. crank shell l3 end. cums in the direction iiulicu'tecl' by line arrows ff-Zui l valve is provided Willi 'two rotary valve poi-ts 40 and 10$) each oi? w iicii registers first with an nuclei; port -41. which communicates with the vapor force 121mm 21 and then i'egietezs with fihe feedins vzmoi' port 18 which communic'aes with lime eucylinder. The registering successivcly of each of said celery vel've ports and meme Off valve" and of an inlet valve, i'esceelively fi iius the vapor is first forced iii-om *uiie loi'oe pump through firsi', one anal time the Ollie/ref rotary valve ports and re mains for an. interval of time wichin the hollow im'ieriorEQU of the wot-a1"! valve 31 eiuci ell-en passes out time h some rotary valve pore ineo the engine cylinder, simi Early to the action which occurs in'the engine construction shown in Fig, 1. And similerly, also, there is no communication be.- twcen the force pump 21 and the hollow interior 320 of this modified rotary valve during the interval in which the feeding vapor port 18 is uncovered by'lhe engine piston 14. And similarly also the coinm'essecl vapor, gczl'iile remaining in said hollow interior 3290;? the rotary valve, is subjected co bhe iii action of the cylimier.
The general operation of the engine is mental heating end measuring chamber end thenc'ulliing oil communication between said. chamber and said pump and allowing the compressed char e l11 said chamber to be dis charged .clii-ectly niece the cylinder. Emismuch as the vefioif is highly compressed whilcfihe pisionis at the bottom oi." is stroke, and inasmuch as the vapor is compressed still more when the piston rises, it is obvious that the entire ignition stem of the engine 'mey be dispensed with Where the pressures are sufiiciently high. Such an arrangement however is not in most cases considered. desirable Where the fuel is mixed with the air before entering the engine cyliu (lei: t is also obvious that the liycliocau icon liquid 0;- gaseous fuel may be mixed with the. air at any point in the cycle of operations prior to thei'ii'ing' of the charge in the engine cylinder. 'llor instance, for certain classes of work it ('iesireble to feed the fuel into the feeding vapor port 18, thereby avoiding all Contact of the fuel, with she rotary valve 31 or 310 of the force pump 21.
The inventicn'as a Whole is unusually reliable in operation by reason of the positive feeding of a definitely measured and heated vapor charge to the engine irrespective of engine speed. The mechanical c0nsti'uclion is without week'ti'appy parts and is therefore not likely to out of order. Very flexible engine control is obtained irrespective of atmospheric conditions endilie engine involves no delicate machine work in its construction and may be constructed at low v TI claim my invention: 1
