Abstract: A throttle body or actuator for an engine, comprising a main body which defines at least one supply duct having a through lumen for a gas mixture, a choke valve placed inside said supply duct so as to modify said through lumen. The choke valve is provided with an occluding body connected to a control shaft, at least partially housed in a seat in the main body. The control shaft, inside the seat and on the side of the occluding body, is provided with a first gasket adapted to prevent the penetration of dirt and gas from the supply duct. Downstream of the first gasket, on the side of the control shaft, at least one vent is provided, adapted to allow the expulsion, outside the seat, of any gas which has leaked through the first gasket.

Abstract: A piston pump for feeding a liquid in a vehicle having at least one piston, which is configured to cyclically slide inside a housing between a top dead centre and a bottom dead centre. The liquid is usually fed along a main feeding direction from a suction duct to a delivery duct. The piston pump has two solenoid valves, which are each arranged in the suction duct and in the delivery duct, respectively, and are designed to be operated by an electronic control unit so as to reverse the liquid feeding direction from the main feeding direction to a secondary feeding direction opposite the main liquid feeding direction and/or so as to adjust the cylinder capacity of the piston pump. The piston is operated by an electromechanical actuator, in particular comprising an electromagnet.

Abstract: An electric machine having a tangential architecture comprising a rotor, rotating about an axis of rotation, a stator, coaxial to the rotor with respect to said axis of rotation, the stator comprising a casing which at least partially incorporates the rotor, a power supply body which incorporates a controller for the actuation, the power supply and the control of the electric machine. The power supply body is located outside the stator and parallel to the axis of rotation in a position substantially tangent to the casing of the stator. The controller includes a power module to power the electric machine. The power module is provided with a main heat sink, suitable to dissipate the thermal power emitted by the power module itself, and the power module is thermally insulated from the remaining controller.

Abstract: An electronic control device for controlling a vehicle battery pack comprises a non-programmable monitoring and actuation unit and a two-way serial communication interface. The non-programmable monitoring and actuation unit is electrically and operatively connectable to the battery pack and to each of the battery cells C to detect analog battery parameters P, including at least the magnitudes of battery voltage Vb and battery current Ib, in addition to temperature (Tc1, Tcn), current (Ic1, Icn) and voltage (Vc1, Vcn) of each battery cell C. The non-programmable monitoring and actuation unit generates monitoring signals Sm representative of the detected analog battery parameters P. The two-way serial communication interface is connected to the non-programmable monitoring and actuation unit to receive the monitoring signals Sm and to supply the aforesaid at least one command signal Sc.
