Abstract (en)

[origin: WO2011158167A2] An internal gear fluidic machine (1), in particular a pump for the lubrication circuit of a motor vehicle engine, comprises a member (13) for regulating the flow rate depending on the fluid pressure conditions in a fluidic circuit in which the machine (1) is connected. The regulating member (13) is axially slidable, without rotating, in a seat (12) formed in the body (10) of the machine (1) and has a first surface (18) for pressure application, which is permanently exposed to said pressure conditions and is arranged, when a threshold is exceeded, to cause a sliding of the regulating member (13) in order to create a fluid recirculation path through the machine (1). A method of regulating the flow rate of a fluidic machine and a combined pump (1, 100) for the automotive field, using the machine (1) as a pump for the lubrication circuit, are also provided.
