Abstract

A pumping system (30) for a fluid, in particular lubrication oil of a motor vehicle engine, comprises a fixed displacement pump (10) and a continuous variator (15, 16) of the transmission ratio according to which motion is transmitted to the pump (10) by a driving member (11). The variator is integrated with the pump into a common body. A pump with fixed displacement and variable delivery rate and a method of regulating the delivery rate of the pump are also provided.
