Abstract (en)

[origin: EP1310676A1] The pump (1) has an interior helicoidal rotor (2) with a helicoidal stator cavity and motors. A driving rod (5) is coupled by couplings (6,7) to a driving shaft (3) and to an end of the rotor. Each coupling comprises a spherical head (12) fixed to the rod and received in a cylindrical cavity (14) coaxially fixed to the end of the rotor. A ball (15) is part sheltered in a dish (16) of the spherical head and part in a lateral recess (19) of the cavity.
