Abstract: The present disclosure relates to internal combustion engines in general. Some embodiments may include a drive device for a high-pressure fuel pump of an internal combustion engine. It may include an eccentric ring in frictional connection with a drive shaft for converting a rotational movement of the drive shaft about a drive shaft rotational axis into a translational movement; a tappet spaced apart from the eccentric ring for passing on the translational movement from the eccentric ring; and at least two pivoting bodies disposed between the eccentric ring surface and the tappet surface and in contact with the eccentric ring surface and with the tappet surface. The eccentric ring may include at least one flat eccentric ring surface. The tappet may include at least one flat tappet surface. The pivoting bodies may each include a respective extension axis running parallel to the drive shaft rotational axis and pivot about the extension axis.

Abstract: The disclosure relates to internal combustion engines in general and may be applied to a high pressure pump for a fuel injection system of an internal combustion engine. In some embodiments, the pump includes: a pump housing including a piston guide and a plunger guide bore; a piston for compressing a fuel, the piston guided in the piston guide; and a roller plunger including a plunger skirt and a roller, the roller plunger transferring a translational movement from a cam of a camshaft driven by the internal combustion engine to the piston. The plunger skirt may include an outer region directed away from the roller and symmetrical about a plane of symmetry and an overall mass distributed asymmetrically about the plane of symmetry.

Abstract: The present disclosure relates to fuel systems. Some embodiments of the teachings may include a fuel pump comprising: a pump piston having a longitudinal centerline; a camshaft with at least one cam; a roller tappet arranged between the pump piston and the cam; and a tappet body and a roller rotatably held on the roller tappet. The pump piston and the tappet body may be movement-coupled with regard to movements in directions parallel to the piston longitudinal centerline. The roller may be in contact with the cam. The longitudinal centerline may intersect a geometric axis of rotation of the roller. The tappet body defines a tappet body longitudinal centerline parallel to the piston longitudinal centerline. The tappet body longitudinal centerline, in a projected view oriented parallel to the geometric axis of rotation of the roller, runs with a lateral spacing to the piston longitudinal center line.

Abstract: A fuel-injection system comprises a control unit that controls the injection of a fuel cylinder of an engine such that an injection volume of the fuel is injected into one of the cylinders during each work cycle of the engine. To this end, the control unit actuates an inlet valve and/or outlet valve such that, during pump strokes of a high-pressure pump which follow one another, a different high-pressure volume of the fuel per pump stroke is delivered into a pressure accumulator during at least two consecutive work cycles. The high-pressure volume that is produced per work cycle corresponds to the injection volume that is removed from the pressure accumulator per work cycle and is constant during each of the consecutive work cycles.

Abstract: A safety arrangement for a motor vehicle includes an airbag and a crash sensor system. The airbag is normally folded together in a non-activated basic state and is able to be inflated with different volumes. The crash sensor system detects a vehicle impact and emits an activation signal. The crash sensor system includes both a pre-crash sensor system and also an in-crash sensor system, and emits a pre-crash activation signal as activation signal upon detection of an impending collision. The in-crash sensor system detects an actual impact and emits an in-crash activation signal (backup) if the pre-crash sensor system has previously not detected the impending collision and has not emitted a pre-crash activation signal. The airbag may be inflated to a larger airbag volume and to a relatively smaller airbag volume in an in-crash mode.

Abstract: The invention relates to a safety arrangement for a vehicle, in particular for a motor vehicle with an airbag (2), folded together in the non-activated basic state, which on a triggering of the safety arrangement (1) by an activation signal is able to be inflated with different volumes in the direction of the interior of the vehicle by means of a gas generator (3), and with a crash sensor system which detects a vehicle impact and emits the activation signal for this. According to the invention, the crash sensor system comprises both a pre-crash sensor system and also an in-crash sensor system, wherein the pre-crash sensor system generally already detects an impending collision before an actual impact, and for this circumstance emits a pre-crash activation signal as activation signal.

Abstract: The invention relates to a demolition hammer and/or hammer drill comprising a percussion generating device having a percussion piston moving axially back and forth. In a main percussion mode, the percussion piston impinges upon a tool which can move along a limited axial path straight into a main percussion direction. In a free percussion mode, the percussion piston indirectly impinges upon a percussion changing device, and by means thereof upon the tool, in a free percussion direction opposite to the main percussion direction. The impact surface of a tool shaft and the impact surface of a free percussion ram are placed opposite an impact surface of the percussion piston in such a way that the free percussion ram is removed from the effective area of the percussion piston by a return spring in the main percussion position.
