  • this invention has for a particular object to provide such Rotary Engine, that based on the mentioned above " OEI Basic Principle of Rotary System ", therefore any apex portion of either bi-apex or tri-apex Rotor can be made and constructed in an "arched form", for which a 180 degrees angular arched apex portion of Rotor Form is suitable for the purpose of installing an arched sealing elements which will enable to solve the conventional corner leakage such as in the Wankel Type of Rotor.
  • the present invention has for a particular object to provide such Rotary Engine, an improved form of the inner surface of the outer component, that in order to cooperate with the above mentioned 180 de­grees arched apex portion of Rotor, therefore the inner surface of the out­er component is made and constructed also in "arched form" and in such a continuously and only in accordance to the relative rotations of the Ro­tor, in this case, to be exact, is in accordance to the relative positions of the arched apex portion of the Rotor during its relative planetary motions therearound the eccentrical hubshaft provided with the proper speed ra­tio as previously mentioned.
  • Such continuous arched form of the inner surface of the outer component will form such a specific, somewhat like “arcaded inner Housing wall” or “arcaded internal cavity” within the outer component.
  • the outer surface of the Rotor, between two adjacent arched apex portions will be constructed and shaped to form a specific, somewhat like "arcaded outer surface of the Rotor" which shapes connecting the two adjacent arched apex portions of the Rotor will be relatively decreased from 180 degrees arched shape at each apex portion of the Rotor to become minimum in the middle depend­ed to the determined angular shape of the outer surface of the Rotor and such form of cooperating shapes between the outer and inner component will function as the working chambers with effective compression ratio, or as intake chamber and outlet chamber which within each side surfaces will be sealed by means of including sealing elements or rings along the side surfaces of the Rotor and engaged with the Rotor apex sealing rings.
  • the Second Shape has always perfect arched shape of 180 degrees du­ring its relative rotations, provided that the Rotor will maintain its rotations to the speed ratio as men­tioned in the OEI Basic Principle of Rotary System.
  • Such situation as mentioned above will enable the arched 180 degrees apex portion shape of Rotor to perfectly macth to the specific arched form of the inner Housing wall as previously mentioned, which condition will be maintained accurately, precisely subject to the punctuality of the Rotor rotation to its basic speed ratio.
  • the present invention has for a par­ticular object to provide such Rotary Engine, that such specific form of the arcaded internal surface of the outer component or the inner Hous­ing wall form, can be made and constructed alternatively by a special cutting and shaping tools or equipments which comprise of the same Ro­tor (which is made by conventional system) but provided with proper cut­ting tools attached or secured on each arched apex portion of the said Rotor, which Rotor will be rotated by means of intermeshing gear train to the same construction as previously described and to the fix compo­sition as hereinafter will be explained.
  • the present invention has for a particular object to provide such Rotary Engine, to have each one or more intake and outlet passage/s within the suitable positions of the outer component, which means for communicating the concern working chambers, either with or without val­ves, for alternately feeding sufficient air or mixture of fuel air into its proper variable volume working chambers that are defined during its rela­tive rotations between the cooprating shapes of the inner and outer com­ponents and flow it out after the stage of ignitions and combustions has been concluded perfectly.
  • Such spark plu or fuel injector can be located within the suitable positions of the compression chamber of the outer component.
  • Such fixing or securing the separate parts may be requiring certain seal­ing elements or gasket to be applied for leakage preventions.
  • the invention contemplates the chro­me plated inner Housing wall surfaces and chrome plated Rotor rings for the purpose to obtain the smooth and hard chrome surface which has a good affinity for lubricating oil and to reduce the wearing rate signifi­cantly.
  • the half ring sealing elements can be constructed to have longer legs in order to continue and engage properly the side surface seal­ing rings for perfect sealing purposes, for which several alternative model of rings and seat position can be introduced.
  • Such Rotary Engine having bi-lobed of epitrochoid Housing, that beside using the arched tri-apex Ro­tor as has been described previously, such engine may have another model of similar tri-apex portion Rotor but with 6 (six) lobed of arcaded outer surface forms as follows:
  • Such Rotor is still comprise of three arched apex portion of the same size but the outer arcaded surface between every two adjacent apex portions will be made and constructed accurately into 2 (two) lobed of arcaded out­er surface Rotor form which form will be exactly following the 2 (two) lobed arcaded inner surface of the Housing wall, which is used for the compression chamber in the conventional model, and thereafter the both cooperating shapes of the inner Housing wall surface and the new model of 6 (six) lobed arched outer surface of Rotor can match perfectly each other because each cooperating shapes have the same surface form when they meet within the compression stage and after every exhaust stage or just beginning the intake suction stage, and therefore such typical special design is able to prevent the interfere of
  • the­refore must be provided with a channel within the arcaded inner surface of the Housing wall, which channel will function as the compression cham­ber, where the size as well as the form of such channel will be based to the effective compression ratio as may required for such Rotary Engine.
  • a similar channel can also be constructed between the two adjacent arched apex portion within the arcaded outer surface of said Ro­tor, which channel will function to limit the effective compression ratio.
  • Such sliding valve is controlled by special cam to be made and constructed either integral with the Maincrankshaft or by separate camshaft. As constructed in the conventional model such channel may also be cons­tructed without provided by any sliding valve for proper operation. It is further object of the invention to provide such Rotary Engine that in order to be able to control the Rotor's Rotations in accordance to its each typical basic speed ratio, therefore an intermeshing gear train will installed between the Rotor and the Maincrankshaft, and in order to ob­tain maximum space efficiency and minimum gearing ratio, therefore the composition of such intermeshing gear train will be fixed to the arrangement as hereinafter described:
  • I.I.G.P./I.I.G. - a/b 1/2
  • a/b I.I.G.P./I.I.G. x c/d x e/f.
  • 1/2 refers to the basic eccentric ratio for Type One Rotary Engine.
  • 2/3 refers to the basic eccentric ratio for the Type Two Rotary Engine.
  • the pitch diameter of such maincrankshaft can be increased if the pitch diameter of the Internal Involute Gear Pinion and therefore also the pitch diameter of Internal Involute Gear as well, be increased to the ex­tend that sufficient space for side sealing elements is provided properly and therefore the intermeshing gear train composition can be determined as follows : Assuming the I.I.G.P./I.I.G.
  • Pinion Gear may change its rotation to the opposite of the Maincrankshaft direction subject to that the I.I.G.P./I.I.G. is smaller to the basic eccentric ratio (1 : 2 for Type One Rotary Engine and 2 : 3 for Type Two Rotary Engine).
  • the Pinion Gear will ro­tate to the same dir ection of the Maincrankshaft rotations.
  • the invention has a particular object to provide such Rotary Engine that as conventionally constructed both end of the Maincrankshaft and the Housing will be provided with proper rubber seal elements and suitable ball bearings, and within the hollow shaft of the first cluster gear assembly will be provided with suitable needle bearing or if the space is sufficient with suitable ball bearing at both side, and the both end of the shaft of the second cluster gear assembly will be provided with suitable sleeve bearing or suitable ball bearing depended to such neccessity of the construction or manufacturing requirements, including all suitable spacer thereof and suitable keys as well.
