摘要： A diagnostic system for a lubrication circuit of an internal combustion engine of a vehicle. The system includes a viscometer for detecting the viscosity of a lubricating liquid of the lubrication circuit, a temperature sensor for detecting the temperature of the lubricating liquid, and a control unit to acquire the state of the lubricating liquid, given by the viscosity detected for a given lubricating liquid condition, which includes the lubricating liquid temperature and the date of last replacement of the lubricating liquid, and for a given condition of use of the engine, and to assess the state of the lubricating liquid by comparing the detected viscosity of the lubricating liquid with the viscosity reference values stored in the database in the same or similar condition of lubricating liquid temperature, date of last replacement of the lubricating liquid and use of the engine.

摘要： Pump (1) comprising:—means (2) for pumping a working fluid;—an electric motor (3) for actuating the pumping means (2); said motor (3) comprising a stator (31) and a rotor (32) that interact for the actuation of the pumping means (2); said rotor (32) being rotatable about an axis of rotation (320);—an electronic unit (4) for controlling the electric motor (3);—a conduit (5) for the delivery of the working fluid downstream of the pumping means (2);—a line (6) for cooling the electric motor (3) and the electronic unit (4), said cooling line (6) being permanently open and drawing off some of the working fluid processed by the pumping means (2). The cooling line (6) comprises a first conduit (61) which is developed from a delivery area (22) of the pumping means (2).

摘要： A pump (1) for pumping a working fluid includes an electric motor (3) for actuating the pump and a motor (3) having a stator (31) and a rotor (32) that interact for the actuation of the pump. The rotor (32) is rotatable about an axis of rotation (320). The pump includes an electronic unit (4) for controlling the electric motor (3), a conduit (5) for the delivery of the working fluid downstream of the pump, a line (6) for cooling the electric motor (3), and the electronic unit (4). The cooling line (6) is permanently open and drawing off some of the working fluid processed by the pump. The cooling line (6) includes a first conduit (61) which is developed from a delivery area (22) of the pump.
