摘要： Fluid pump (10) comprising a hollow body (100) in which a stator (101) and an external rotor (106) of an electric motor are mounted. The external rotor (106) is rotatably mounted about a main axis (X-X) and has an internal cavity (25) connected to an inlet port (114) and an outlet port (115) arranged to allow the inflow of a fluid into said internal cavity (25) and the outflow of said fluid from said internal cavity (25), respectively, an internal rotor (111) rotatably mounted in the internal cavity (25) so as to be free to rotate about a secondary axis (Y-Y), a vane (109) slidably guided in a slot (110) which is formed in the internal rotor (111) so as to pass through said rotor in a through manner and has a first end and a second end, wherein the first end is provided at a pivot (108). The internal rotor (111) and the vane (109) cooperate in such a way as to divide in a cyclic and fluid-tight manner said internal cavity (25) at least into a first chamber with variable volume and a second chamber with variable volume, said chambers communicating with said inlet port (114) and said outlet port (115), respectively. The pivot (108) is oscillatably mounted in the external rotor (106) so that the external rotor (106), by rotating about its main axis (X-X), entrains in its movement said pivot (108) of the vane (109) and the internal rotor (111), which is brought into rotation by the vane (109) and rotates idly about its secondary axis (Y-Y).

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： A hydraulic device for controlling braking comprises a master cylinder and a brake booster. A piston (38) of the brake booster defines a first and a second chamber (39, 40), associated with communication means to establish a communication between the chambers (39,40) and, during braking, to cut off such a communication and to establish a communication between chambers (39) and a discharge chamber (35b) of the master cylinder. The piston (33) of the master cylinder is driven by a drive piston (34) and it is so shaped as to define, together with the plunger (37) of the piston (38) of the brake booster, a hollow space (45) through which the first chamber (39) is put in communication with either the second chamber (40) or the chamber (35b) of the master cylinder (12).
