Abstract (en)

A volumetric fluid machine includes a stator (2) in which are placed, with rotatory motion, a first rotor (6) and a second rotor (7), mutually associated and with conjugated external profiles (10, 11). The first rotor (6) has a profile (10) presenting at least a lobed part (10a), associated to an inner surface (4) of the stator (2), which defines, together with the inner surface (4) of the stator (2) and with the profile (11) of the second rotor (7), at least a chamber (12) with cyclically variable volume from a maximum value to a minimum value when the first rotor (6) rotates around a corresponding axis (X), in order to exchange energy with a moving fluid. Moreover the lobed part (10a) delimits, together with the inner surface (4) of the stator (2), a first gap (14) capable to guarantee fluid tightness.
