Abstract: The cabs of the series, which are of different dimensions, each having a driver cab and a shield for shielding the front and sides of the vehicle frame. The shield is in the form of a continuous fascia disposed below the driver compartment, the height of this latter being the same for all vehicles of the series whereas the height of the fascia is different for the various vehicles of the series. Thus cabs of different overall heights are obtained by combining driver compartments of constant height with fascias of different height.

Abstract: A leaf spring attachment comprises a support for fixing to the structure of the vehicle and an omega-shaped bracket fixed to the support so as to define two facing walls between which a pin for supporting the eye of the leaf spring is mounted. The support comprises first and second metal strips welded together centrally in an X arrangement.

Abstract: A high-pressure, continuous-delivery piston pump, controlled as a function of engine speed and load, supplies fuel to an accumulator supplying injectors. On the intake side of the pump, there is provided a throttle for metering the amount of fuel supplied by the pump. Via operating signals, the throttle is regulated by an electronic control device in such a manner as to supply the pump and pressurize only the amount of fuel strictly required for operating the injectors and the engine, thus eliminating any energy losses caused by fuel feedback to the tank, and drastically reducing fuel consumption.

Abstract: A linear actuator for tipping the driver's cab of a commercial vehicle comprises a telescopic strut of the screw-and-nut type, in which the screw is rotated by an electric motor and the nut is associated with a hollow shaft movable axially along the screw and connected at its top to the vehicle cab.

Abstract: Upstream of the electrically operated fuel injectors for each engine cylinder there is connected a common pressure reservoir subject via a valve to the action of a continuously delivering fuel pump as a function of the engine speed and load. The common pressure reservoir is continuously connected by means of an annular chamber and a throttle to a channel in each fuel injector. Each fuel injector has a solenoid or magnetic valve operable for each fuel injection process and during the operation thereof connects said channel with a fuel return pipe and consequently relieves or releases the nozzle needle closing the fuel injection opening, thus releasing the discharge of fuel from a pressure chamber located directly upstream of the fuel injection opening. The channel is continuously connected via a throttle bore bridging a check valve to a control chamber controlling the nozzle needle movement.
