Abstract

Improvements in rotary pumps especially for servo-steering; with a ring of curves that is housed inside a casing and between two front plates, with a cylindrical rotor that is arranged in it and which is provided with working blades that can be moved in the radial direction, thus As with a suction chamber that is equipped with an inflow opening, which is arranged axially within the area of the ring of curves, the chamber is in union with the cells, which are constituted by the ring of curves and the aforementioned motor between the working blades, through the suction bags that are arranged on the two front plates; This pump is characterized by the fact that the suction chamber surrounds the ring of curves starting from the inflow opening to the suction bags on the front plates; only in part and that the same camera has been executed at its ends to the style of the blades.
