Auto suction hybrid pump

Hybrid pump (1) having a housing (2), into which at least one suction connection (10) and one pressure connection (11) open, and in the housing chamber (3) of which, which is enclosed essentially in circular manner, a rotor (5) is arranged eccentrically, which has a number of rotor vanes (6) on its circumference, which are spaced apart, and radially arranged at least in some sections, and made of a material that is resiliently, elastically deformable,

• wherein
• the eccentricity (14) of the rotor (5) relative to the housing chamber (3), as well as the elasticity of the rotor vanes (6) are selected in such a manner that in a first range of low rotational speed, each rotor vane (6) does not rest against circumference segments (4) of the housing chamber (3) with its radially distant end region (7), or rests against them only part of the time, during a revolution of the rotor (5) so that the hybrid pump (1) works in a not self-priming manner, whereas in a second range of greater rotational speed, all of the rotor vanes (6) rest against the inner wall (4) of the housing chamber (3) with their radially distant end regions (7), under the influence of centrifugal force, essentially during the entire revolution of the rotor (5) so that the hybrid pump (1) works in a self-priming manner.
