Title
(EN) ROTARY PISTON ENGINE
(FR) MOTEUR A PISTON ROTATIF
Abstract
(EN)
The rotary piston engine consisting of the casing (1) in which the cavity to locate the main rotor (2) with outer teeth (4) as well as the cavity to locate the secondary rotors (3) with internal cavities (5) are created, where the main rotor (2), on which the symmetrically situated outer teeth (4) are formed, is located inside the casing (1), and where, simultaneously, at least two secondary rotors (3) are located rotatively and symmetrically with respect to the main rotor (2), in said secondary rotors being symmetrically situated at least two internal cavities (5). At least in half-number of teeth (4) of the main rotor (2), the delivery duct (6) for the outlet and the suction duct (7) for the medium inlet are always made. The number of the outer teeth (4) of the main rotor (2) is even, and in secondary rotors (3), odd number of internal cavities (5) is made. The delivery duct (6) and the suction duct (7) are made in each even outer tooth (4) of the main rotor (2). Alternatively, the delivery ducts (6) and the suction ducts (7) can be made in all outer teeth (4) of the main rotor (2).
(FR)
Cette invention concerne un moteur à piston rotatif comprenant un carter (1) dans lequel sont formées une chambre qui va recevoir un rotor principal (2) comportant des dents externes (4), ainsi qu'une chambre qui va recevoir des rotors secondaires (3) comportant des chambres internes (5). Le rotor principal (2) comporte des dents externes et symétriques (4), et vient se loger dans le carter (1). Dans un même temps, au moins deux rotors secondaires (3) sont montés symétriquement au rotor principal (2) et de manière à pouvoir tourner par rapport à celui-ci, lesquels rotors secondaires renferment au moins deux chambres internes et symétriques (5). La conduite d'alimentation (6) pour l'évacuation et la conduite d'aspiration (7) pour l'admission du milieu sont toujours présentes en un nombre qui est égal à la moitié au moins de celui des dents (4) du rotor principal (2). Le nombre des dents externes (4) du rotor principal (2) est un nombre pair, tandis que le nombre de chambres internes (5) dans les rotors secondaires (3) est un nombre impair. La conduite d'alimentation (6) et la conduite d'aspiration (7) sont formées dans chaque dent externe (4) paire du rotor principal (2). Dans un autre mode de réalisation, les conduites d'alimentation (6) et les conduites d'aspiration (7) peuvent être formées dans toutes les dents externes (4) du rotor principal (2).
