Abstract: front page image
(EN)A pump or motor comprising a housing accommodating a set of rotors formed by at least two disc-like rotors adapted to rotate by means of parallel shafts having the rotors fastened to them in cylindrical, partly coinciding chambers having such a shape and relative positions of the rotors that the outer surface of each of said rotors is invariably at least at one place tangential to the cylindrical wall of the chamber whilst the outer surfaces of the rotors are tangential to one another along a line parallel to the rotor shafts and located in the plane going through the centre lines of the rotor shafts concerned so that enclosed between the walls of the housing and the outer surfaces of the rotors are formed at least one inlet chamber and one outlet chamber whose volume varies substantially linearly, as a result of the rotation of the rotors, with the magnitude of said rotation.
(FR)Une pompe ou moteur comprenant un carter ou est loge un jeu de rotors formes par au moins deux rotors en forme de disque concus pour tourner a l"aide d"arbres paralleles sur lesquels sont fixes les rotors dans des chambres cylindriques coincidant partiellement ayant une forme et des positions relatives des rotors telle que la surface externe de chacun desdits rotors est invariablement a au moins un endroit tangentiel a la paroi cylindrique de la chambre tandis que les surfaces externes des rotors sont tangentes entre elles le long d"une ligne parallele aux arbres des rotors et situes dans le plan passant par les axes des arbres des rotors concernes de maniere a former entre les parois du carter et les surfaces externes des rotors au moins une chambre d"admission et une chambre de sortie dont le volume varie sensiblement lineairement, resultat de la rotation des rotors, en fonction de l"amplitude de cette rotation.
