摘要： A rotary positive displacement pump for fluids, in particular for the lubrication oil of a motor vehicle engine (61), has a displacement that can be regulated through the rotation of a stator ring (42) having an eccentric cavity (43) in which the rotor (15) of the pump (1) rotates. The stator ring (42) is housed within an eccentric cavity (13) of an external ring (12). A rotary actuator (50), controlled by the electronic control unit of the motor vehicle, causes a synchronous rotation by an equal amount in opposite directions of both rings. The invention also concerns a method of regulating the displacement of the pump (1) and lubrication system for a motor vehicle engine in which the pump is used.

摘要： An adjusting device to be applied to servo-controlled brakes, including in a body (101) a piston (123) arranged to slide internally of a volume having an inlet channel (118), arranged to supply pressurised fluid, and at least one outlet pipe (122) arranged to transfer said fluid to at least one "hydroboost" master cylinder. The volume has a first bore (131) having a section with a first area (S1), and a second bore (133) having a section with a second area (S2), and the piston is arranged to slide inside said volume. The two areas are configured so that the first area (S1) is greater than the second area (S2) according to a predetermined ratio that is arranged to define a predetermined pressure adjustment ratio between the pressure of the fluid entering through the inlet channel (118) and the pressure of the fluid exiting through the at least one outlet pipe (122). The invention also concerns a method for applying predetermined adjustment ratios to at least one "hydroboost" master cylinder.
