Abstract

Dvoprocesni rotacioni motor s unutarnjim sagorijevanjem kod kojeg se toplinska energija pretvara u mehanički rad, naznačen time, što se: - na istom vratilu nalaze usisno-kompresioni cilindar te jedanili dva ekspanziona cilindra, pri čemu je između usisno-kompresionog cilindra i cilindra izgaranja-akumulacije stacionarno smještena akumulaciona komora; - u prvom ekspanzionom cilindru tokom ekspanzije odvija izgaranje goriva i akumulacija dijela oslobođene topline, a u drugom ekspanzionom cilindru ekspanzija-ispuh; - svaki cilindar sastoji od obodnog dijela kućišta (1) i obodnog prstena (2) čije je geometrijsko središte smješteno u geometrijsko središte obodnog dijela kućišta (1); - u svakom cilindru nalazi rotor (3) ekscentrično smješten u odnosu na geometrijsko središte kućišta i prstena,pri čemu je u svom geometrijskom središtu vezan na vratilo (4); - u svakom cilindru nalazi radijalno pokretni potiskivač (5), koji je s jedne strane umetnut u raspor rotora, a s druge strane zglobno postavljen u kružno oblikovani otvor u prstenu, pri čemu potiskivač u svakom cilindru tvori dva promjenjiva volumena, obzirom na smjer vrtnje, volumenispred sebe (A) i volumen iza sebe (B); - rotor (3) i obodni prsten (2) stalno dodiruju u jednoj točci (0); - svaki cilindar zatvara bočnim stijenkama (9) u kojima su ugrađeni ležajevi (10) za uležištenje vratila (4); - u bočnim stijenkama (9) nalaze otvori za usis (6), ispuh (12) ili prestrujavanje medija (11); - svi dijelovi koji se nalaze unutar cilindra međusobno razlikuju po provrtima i kanalima za protok medija; - ovakvom konstrukcijom izbjegava pretvaranje pravocrtnog u kružno gibanje; -promjena volumena odvija u 360 stupnjeva okretajavratila; - konstrukcijom smanjuju termički gubicizračenja; - konstrukcijom omogućuje akumulacija topline i njeno iskorištavanje; - rotirajući dijelovi nepropusno naslanjaju na unutarnje stijenke cilindričnog kućišta i bočne stijenke kućišta; - u bočnim stijenkama uležišteni, a smješteni u uglovimaobodnog dijela kućišta (1) nalaze cilindrični valjci (8) za smanjenje obodnog trenja prstena i obodnog dijela kućišta- kućišta usisno-kompresionog cilindra i cilindra izgaranja-akumulacije uzajamno poklapaju, a kućište ekspanziono-ispušnog cilindra zaokrenuto je i fiksirano za najpovoljniji kut u odnosu na kućišta prethodna dva cilindra; - svi taktovi procesa odvijaju istovremeno u većem broju međusobno i od okoline izoliranih volumena što omogućuje povoljnije termičko vođenje procesa tj. odvođenje topline u vrijeme kompresije, a dovođenje u vrijeme ekspanzije, pri čemu se dovođenjem topline mediju tokom ekspanzije dobiva rad i u vrijeme povećanja i u vrijeme smanjenja unutarnje energije medija; - protok medija kroz sistem osigurava provrtima (7) u rotorima (3), segmentnim žljebovima u rotorima (3) i segmentnim provrtima u bočnim stijenkama (9). Patent sadrži još 3 patentna zahtjeva.A two-process rotary internal combustion engine in which heat energy is converted into mechanical work, characterized in that: stationary storage chamber; - in the first expansion cylinder during expansion, fuel combustion and accumulation of part of the released heat takes place, and in the second expansion cylinder, expansion-exhaust; - each cylinder consists of a circumferential part of the housing (1) and a circumferential ring (2) whose geometric center is located in the geometric center of the circumferential part of the housing (1); - in each cylinder there is a rotor (3) eccentrically located in relation to the geometric center of the housing and the ring, whereby in its geometric center it is connected to the shaft (4); - in each cylinder there is a radially movable pusher (5), which is inserted on the one hand into the rotor gap, and on the other hand hingedly placed in a circularly shaped hole in the ring, the pusher in each cylinder forming two variable volumes volume in front of you (A) and volume behind (B); - the rotor (3) and the circumferential ring (2) are constantly touching at one point (0); - each cylinder closes with side walls (9) in which bearings (10) for bearing the shaft (4) are installed; - in the side walls (9) there are openings for suction (6), exhaust (12) or media overflow (11); - all parts inside the cylinder are distinguished by holes and channels for the flow of media; - with this construction it avoids turning a straight line into a circular motion; -volume change takes place in 360 degrees of rotation of the shaft; - reduce thermal radiation losses by construction; - the construction enables the accumulation of heat and its utilization; - the rotating parts rest impermeably on the inner walls of the cylindrical housing and the side walls of the housing; - cylindrical rollers (8) are located in the side walls and located in the corners of the circumferential part of the housing (1) to reduce the circumferential friction of the ring and the circumferential part of the housing - the suction-compression cylinder housing and the combustion-accumulation cylinder overlap, and the expansion-discharge housing it is rotated and fixed for the most favorable angle in relation to the housings of the previous two cylinders; - all process cycles take place simultaneously in a larger number of volumes isolated from each other and from the environment, which enables more favorable thermal control of the process, ie heat dissipation during compression and supply during expansion, whereby heat transfer to the medium during expansion reducing the internal energy of the media; - the flow of medium through the system is ensured by holes (7) in the rotors (3), segment grooves in the rotors (3) and segment holes in the side walls (9). The patent contains 3 more patent claims.
