Abstract: 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.

Abstract: An internal gear fluidic machine, in particular a pump for the lubrication circuit of a motor vehicle engine, comprises an operating part including an external gear (2) and an internal gear (4), which is housed within an axial cavity (25) of the external gear (2) and meshes with the latter. The external gear (2) is associated with a translating mechanism (8, 22), arranged to cause an axial sliding thereof relative to the internal gear (4) in order to vary the capacity and the fluid flow rate of the machine. The translating mechanism (8, 22) defines a first capacity, adjustment space (24) in communication with a high pressure chamber (48) of the machine, and a second capacity adjustment space (15) where pressure conditions exist that are dependent on the operating conditions of an element, different from the high pressure chamber (48), of a fluidic circuit in which the machine (1) is connected. The translating mechanism (8, 22) causes the sliding of the external gear (2) in response to the pressure conditions existing in the first or the second capacity adjustment spaces (24, 15), or in response to the combination of the pressure conditions existing in both spaces. The invention also concerns a method of varying the capacity of an internal gear fluidic machine.
