Abstract
Eccentric screw pump, with a stator in the form of a hollow worm and a rotor in the form of an endless screw arranged eccentrically about the axis of the stator, which has a fillet pitch less than the stator and to which a rotary movement is arranged within the latter around the axis of the rotor and simultaneously a circular movement in reverse movement of the rotor axis around the axis of the stator through a coupling articulated by an articulated shaft, which traverses a pump box, substantially circular cylindrical shape, which follows the stator on the side of the pressure, through which flows the material to be driven, characterized in that the articulated coupling (28) and a part of the articulated shaft (30) are arranged inside a cylinder (44; 44'; 44'') hollow squeeze, which is arranged with the same axis as the rotor (12) and attached to it to perform circular movements common with the same mo and only leaves an annular space between said cylinder and the inner wall of the pump housing (22), whose radial width in the narrowest place is smaller than the eccentricity (e) and in the widest place is more small that triple the eccentricity of the rotor.
