By means of its pin stantially tangentially relative to the cylindrical surface 8, each sliding sleeve is in Contact with the partly con of the piston, its open end adjoining one of the sliding centric outer periphery v10, and the partly eccentric outer 40 sleeves that are reciprocated by the cylindrical surface periphery @11 of the engine piston. It will be noted of the piston. that eccentric periphery :11 is a substantially regular It is thus achieved that the expanding combustion curvilinear surface which is tangent, at each end, to the gases, after ignition, imping upon the main blade in the cylindrical inner surface of the cylinder 1, and which has piston at as favourable an angle as possible, and thus with as great an effect as possible, without the gas ñow having to be deñected over an angle, which latter entails great losses. In addition the internal combustion engine according to the invention may be so constructed that each sliding sleeve is guided by a guide means projecting substantial ly radially from the periphery of the housing and sur rounding the sliding sleeve, which guide means is closed by a cover having an inwardly projecting tubular portion which partially extends into the sliding sleeve and which has a ybottom whose shape is adapted to the shape of the sliding sleeve and the periphery of the piston, a heli cal spring acting on the sliding sleeve being arranged about said inwardly projecting tubular portion. a 4maximum eccentricity, relative to the cylinder 1, at a point substantially midway of its tangent ends. Helical compression springs 1-2 ensure permanent contact be tween the pins 8 of the sliding sleeves and the piston 9. The wings 7' and 7" of the sliding sleeve bottom 7 laterally seal the engine piston 9. A counter-weight 13 effects the balancing of the piston 9. If the engine is equipped with a double or multi-bladed piston, thus a piston with two or more main blades equi distantly spaced over its periphery and two or more con centric and eccentric faces equidistantly spaced over the periphery, the counter-weight 13` is supertluous. A stationary compression chamber 15 is provided in peripherally adjacent relation to each. sliding sleeve, on the trailing side of the associated sliding sleeve as con As a result the rotary piston and the sliding sleeves are sidered with respect to the direction .of rotation of the the only moving parts and are entirely sealed from the 60 piston as indicated by the arrow 14. Each compression atmosphere, while only the outer surface of each sliding chamber 15 is so oriented that its longitudinal center line sleeve and the steel pin which is in contact with the pe forms a very small acute angle with a tangent to the circu riphery of the piston, are sliding. The piston springs can lar periphery of the housing 1. The compression cham be omitted and only one pressure spring per sliding sleeve is necessary. Furthermore corrosion is considerably 65 bers are formed by a circular-cylindrical casing 16 or as appears from FIGURES 5 and Sa-are formed by a restricted. In the following description the improvement will be elucidated with reference to the accompanying drawings, in which: FIGURE l is a section on line I-I in FIGURE 3,‘ and thus normal to the main shaft of the internal com bustion engine according to the invention; casing 16’ which in cross-section comprises two parallel straight sides and two curved sides, as. well as by an end wall 17. In the embodiment according to FIGURE l, a screw threaded spark plug hole -18 is provided in the end wall 17 to receive a spark plug 13a. In the embodiments ac 3,094,840 cording to FIGURES la and 5a this hole 18 is provided in the side wall of casing 16. The positions of the sliding sleeves 5 relative to the as sociated compression chamber 15 in the different phases of the four stroke operating cycle clearly appear from FIGURE 1. The guide means 4 are permanently closed at the outer side by covers 19, which covers also form tubular inward projections 2t) which extend into the slid ing sleeves 5 and have a bottom 21 whose shape con «forms to the shape of the bottom of said sleeves and of 5 and 5a) to imping upon the main blade Z5 at the right moment. With the arrangement of FIG. 5, it’ will be noted that the initial ignition will take place adjacent the opening 18', and that the thus ignited gases in the passage direct ly communicating with the opening 18’ will, through the opening `40, ignite the gases in the central passage. In turn, the gases ignited in the central passage will, through the opening 41, ignite the gases in the third passage, or the upper passage as viewed in FIG. 5a. 'I'here is thus piston. In the embodiment according to FIGURES l to 4 inclusive the helical spring y1?. is located in the space between the guide means 4, the cover 19 a-nd the tubular a progressive impingement of gases against the blade 25. It is also possible to shape the compression chamber 15 such that the longitudinal section is: triangular with the apex located in the point of contact on the inner periphery projection 20 above the sliding sleeve 5, whereas said spring is disposed within the sliding sleeve in the cm bodiment according to FIGURES 5 and 5a. Through this last-named arrangement the radially directed guide cylinder. The cross~section of the chamber may be rec tangular, as shown in FIGURE 6a». The average direction the concentric peripheral surface portion 10 of the engine of the cylinder (vide FIGURE 6i). Both sides, meeting in the apex 42, practically touch said periphery of the means 4 can be much shorter. In order that the sliding sleeve wings 7’ and 7’l pro vide for the pin 8 to yfreely follow the piston periphery 10, 11, the cylinder covers 2, 3 are recessed and ground to form a cylinder segment, -as at 2.2. The engine piston or rotor 9 comprises a hollow, ñat disc including axially spaced end walls and a peripheral wall joining the end walls, the eccentric periphery 11 of which is entirely closed, but the concentric periphery 10 of which is largely open, so that there is a gap of a width in which the explosion surge leaves said compression chamber 15 is substantially normal to the main blade 25. Finally the lateral sealing of the piston 9 may be effected by means of axially slidable sealing rings 43, 44, which are guided by pins 45 »and are loaded by springs 46. It will further be apparent from FIGURES 6 and 7, that the engine may be either air-cooled or liquid-cooled. Cooling ribs are designated by 47 and cooling liquid cavi ties by 48. Although the operation of the engine may be considered to be clear, the lfour operating phases are indicated by equalling As seen looking the space in the between direction the piston of rotation end walls according 23, to 30 the letters a to d inclusive in FIGURE 1, a being the de fined space in which air or a fuel-air mixture is being the arrow 14, a radially extending blade 25 is located sucked in, b >a defined space which has just been iilled, adjacent the concentric peripheral portion 10, which its charge being ready for compression, c a defined space blade extends from the periphery to just past the main in which the charge .is being compressed and d the space shaft 6.
