Abstract (en)
[origin: US4808067A] A rotary vacuum pump comprising a stator (1) and a rotor (2), the rotor being rotated inside the stator and the stator including a suction inlet (11) and an exhaust outlet orifice (12), wherein the suction end of the rotor carries at least one wheel (13) having sloping vanes (14) such that any solid particles that may be sucked in are projected thereby in a radial direction towards an annular stator collector tank (15) having a circular opening (16) opening out into the stator cavity (6) and situated in the plane in which said particles are projected by said vanes (14).
