A valve control device for a gas exchange valve of an internal combustion engine has a cam follower lever interacting with the camshaft. A rocker arm rests on the cam follower lever and actuates the valve. An adjusting device acts on the rocker arm to adjust a valve lift. The rocker arm has first and second control surfaces with first and second radii of curvature, respectively, The cam follower lever has a third control surface with third radius of curvature. The first control surface contacts a fourth control surface of a guide element of the engine with fourth radius of curvature. The second control surface of the rocker arm contacts a valve element. The first to fourth radii of curvature are adjusted such that, when adjusting the valve lift, the valve does not open when the cam follower lever rests on a cam base circle section of the camshaft.

An internal combustion engine with combustion chambers into which liquid and gaseous fuel is introduced together with intake air is operated, at least predominantly, with only one type of fuel in a range in which a harmful HC excess is produced by internal combustion. A retrofitting/conversion kit for such an internal combustion engine has at least one securing plate for at least one injection nozzle for gaseous fuel, wherein a supply conduit for the gaseous fuel is connectable to the at least one injection nozzle, wherein the at least one securing plate is an intermediate flange to be connected between a cylinder head of the internal combustion engine and an intake manifold of the internal combustion engine.

An audio signal generating device to be mounted in a vehicle that operates noiseless or at a low noise level generates an audio signal that is audible for other traffic participants so that the risk of accidents is reduced. The audio signal generating device has at least one memory device for storing the at least one audio signal. The audio signal emitted by the audio signal generating device can be adjusted based on the engine speed or travel speed.

A control device for semiautomatic gearshifting mechanisms of motor vehicles has a selector shaft of a gearshifting mechanism and at least one rotatable shifting element acting on the selector shaft so as to rotate and axially move the selector shaft for selecting a gutter and shifting a gear. A switching valve actuates the at least one shifting element for rotating the selector shaft and for axially moving the selector shaft. The shifting element is a shift drum with at least one control curve. The control curve is a groove in the mantle of the shifting element. The control device provides a simplified hydraulic control of the switching valves and has a simplified configuration.

A closure arrangement for a container has a container neck, having slanted grooves extending in a circumferential direction of the container neck. A removable cap has a clamping projection for each one of the slanted grooves, wherein the clamping projections slide in the slanted groove when the cap is removed from or fastened to the container neck. Each one of the grooves is delimited by two opposed slanted surfaces. The width of the slanted grooves measured in the circumferential direction matches the size of the clamping projections in the circumferential direction.

A solenoid valve has a solenoid component having at least one plunger. At least one valve component having a housing and a piston slidably mounted in the housing is provided. The at least one valve component and the solenoid component are connected to one another. At least one seal, connected to the solenoid component or the at least one valve component, is provided for sealing the solenoid valve relative to a support on which the solenoid valve is mounted.

A device for relative rotational angle changing of the camshaft of an internal combustion engine relative to its drive wheel has an inner part connected with ribs or vanes that is located rotationally movably in a compartmented wheel. This driven compartmented wheel has a plurality of compartments distributed around the circumference divided by ribs or vanes into two pressure chambers each, and with the change in rotational angle being produced by their pressurization. To minimize the influence of overlapping alternating torque influences from the valve drive of the internal combustion engine, damping structure is integrated into this device to damp the change in rotational position change hydraulically.

An actuating device for a brake system of a vehicle a housing and at least one piston slide positioned in the housing for loading the brakes with a pressure medium. The brake system has brakes for the vehicle wheels and a control unit connected to the brakes for sending control signals to the brakes. The brakes are supplied via brake lines with the pressure medium and have wheel sensors connected to the control unit. The wheel sensors determine the rotational velocity of the vehicle wheels during a braking operation and send a signal related to the rotational velocity to the control unit. At least one piezoelectric element is positioned in the housing of the actuating device for actuating the at least one piston slide. The at least one piezoelectric element is connected to the control unit of the brake system.
