Abstract

Cette pompe à cavités progressives comportant un rotor hélicoïdal (2) tournant à l'intérieur d'un stator hélicoïdal (3), ledit stator (3) et ledit rotor (2) étant disposés de telle sorte que les cavités (4) formées entre ledit rotor (2) et ledit stator (3) se déplacent de l'aspiration (5) vers le refoulement (6), est caractérisée par le fait que des moyens de régulation hydraulique (RH) sont prévus pour assurer une recirculation interne du fluide pompé entre au moins deux desdites cavités (4) dans des conditions capables d'assurer au moins une fonction parmi la distribution des pressions recherchée le long de la pompe, la stabilisation des températures, le contrôle des débits de fuite, et la compensation des volumes de gaz comprimé.

Claims (11)

1. Pompe à cavités progressives comportant un rotor hélicoïdal (2) tournant à l'intérieur d'un stator hélicoïdal (3), ledit stator (3) et ledit rotor (2) étant disposés de telle sorte que les cavités (4) formées entre ledit rotor (2) et ledit stator (3) se déplacent de l'aspiration (5) vers le refoulement (6), caractérisée par le fait que des moyens de régulation hydraulique (RH) sont prévus pour assurer une recirculation interne du fluide pompé entre au moins deux desdites cavités (4) dans des conditions capables d'assurer au moins une fonction parmi la distribution des pressions recherchée le long de la pompe, la stabilisation des températures, le contrôle des débits de fuite, et la compensation des volumes de gaz comprimé.
2. Pompe selon la revendication 1, caractérisée par le fait que les moyens de régulation hydraulique (RH) sont agencés pour assurer une recirculation interne du fluide pompé entre au moins deux cavités (4) adjacentes.
3. Pompe selon la revendication 1 ou 2, caracté-risée par le fait que les moyens de régulation hydraulique (RH) sont agencés pour assurer une recirculation interne du fluide pompé entre au moins deux cavités (4) situées dans la région de la pompe (1) voisine du refoulement (6).
4. Pompe selon la revendication 1 ou 2, caracté-risée par le fait que les moyens de régulation hydraulique (RH) sont agencés pour assurer une recirculation interne du fluide pompé entre toutes les cavités (4) de la pompe (1).
5. Pompe selon l'une quelconque des revendications 1 à 4, caractérisée par le fait que les moyens de régulation hydraulique (RH) sont au moins en partie accueillis par le rotor (2).
6. Pompe selon la revendication 5, caractérisée par le fait que les moyens de régulation hydraulique (RH), assurant la recirculation interne du fluide pompé entre deux cavités (4), comportent au moins un canal (8) pratiqué dans le rotor (2) reliant ces deux cavités (4), la régulation hydraulique étant effectuée mécaniquement à
l'aide d'un régulateur (9) disposé à l'intérieur dudit canal (8) et/ou par perte de charge.
7. Pompe selon la revendication 5, caractérisée par le fait que les moyens de régulation hydraulique (RH), assurant la recirculation interne du fluide pompé entre deux cavités (4), comportent au moins un canal périphé-rique (11) accueilli par le rotor (2) et agencé pour assurer la liaison entre ces deux cavités (4) avec régulation par perte de charge.
8. Pompe selon l'une quelconque des revendications 1 à 7, caractérisée par le fait que les moyens de régulation hydraulique (RH) sont au moins en partie accueillis par le stator (3).
9. Pompe selon la revendication 8, caractérisée par le fait que les moyens de régulation hydraulique (RH), assurant la recirculation interne du fluide pompé entre deux cavités (4), comportent au moins un canal hydraulique intérieur (13) accueilli par le stator (3) et agencé pour assurer la liaison entre ces deux cavités (4) avec régulation par perte de charge.
10. Pompe selon l'une quelconque des revendica-tions 1 à 9, caractérisée par le fait que le contact entre le rotor (2) et le stator (3) est desserré par rapport à
une pompe à cavités progressives ne comportant pas les moyens de régulation hydraulique tels que définis à l'une des revendications 1 à 8.
11. Application de la pompe telle que définie à
l'une quelconque des revendications 1 à 10, au pompage de mélanges polyphasiques compressibles et au pompage de fluides visqueux.
