Abstract

L'invention concerne une pompe à cylindrée variable permettant de réguler l'alimentation de plusieurs consommateurs, laquelle pompe à cylindrée variable comprend une bague de commande de cylindrée, pouvant être déplacée afin de régler la cylindrée de la pompe à cylindrée variable, ainsi qu'un dispositif régulateur. L'invention est caractérisée en ce que le dispositif régulateur est en liaison hydraulique avec une chambre de régulation et une chambre de compensation, à partir desquelles des forces de pression peuvent être exercées, dans des directions opposées, sur la bague de commande de cylindrée et dont les pressions ou volumes peuvent être réglés au moyen du dispositif régulateur.
