Abstract

Pompe (1) à vis sans fin excentrique possédant un stator (2) et un rotor (3) entre lesquels la matière à transporter est déplacée, lors de la rotation du rotor (3) dans le stator (2), d'une zone d'entrée (4) du côté aspiration à une zone d'évacuation (5) du côté pression. Selon la présente invention, ladite pompe comporte une tête (7) de rotor, fermant la zone d'évacuation (5) du côté pression, fixée à la face avant (6) du rotor (3) et tournant avec ledit rotor (3), qui comporte au moins un évidement traversant (8) ménagé dans ladite tête (7) de rotor par rapport à la face avant (6) de retenue de tête de manière telle que l'évidement (8) tournant en même temps que le rotor (3) dans le sens de transport (10) ouvre la zone (11, 11') du volume de matière sous pression et qu'une partie (13) de la tête de rotor, exempte d'évidement, maintienne fermée de façon étanche la zone opposée (12, 12') du volume d'aspiration pendant la durée d'ouverture de la zone (11, 11') du volume de matière sous pression.
