ABSTRACT:
The star-shaped rotor (10) accommodated in a discoid cavity (9) defines first chambers (27) formed in the arms (20) of the rotor and second chambers (26) for receiving fluid under pressure delimited between two adjacent arms of the rotor, the constitutive elements of the stator (3-5) being joined together by fastening means (50) extending through the second chambers (26), the lateral faces of the cavity opposite the stator incorporating passage apertures (32', 33) which have a trapezoidal profile with radial edges coincide substantially with the web zones (31) of the arms of the rotor, the edges of which define with the edges of the apertures adjustable restrictions (250, 280) the first chambers (27) communicating permanently with return passages (38) in the stator.
