Abstract: Apparatus suitable for use in reciprocally opening and closing a camshaft-actuated valve may include a rotating camshaft (20) having first and second cams (16, 17, 18) respectively defining first and second amounts of valve opening distance. A cam follower (10, 11, 12) may be defined on a mounting pin (24) so as to operatively engage the first and second cams in an alternating manner. At a first rotational position of the cam follower relative to the camshaft, the cam follower operatively engages the first cam and generates the first amount of valve opening distance. At a second rotational position, the cam follower operatively engages the second cam and generates the second amount of valve opening distance. A valve lever (6) transmits the respective generated first and second amounts of valve opening distance to the valve. A locking device (50) releasably locks the mounting pin and cam follower in the respective first and second rotational positions.

Abstract: A method and apparatus are provided for impulse charging an internal combustion engine having at least one cylinder in which a piston moves in a stroke movement. The apparatus includes a selectively energizeable magnetic surface disposed in a charging duct of the engine and a closure element disposed in the charging duct relative to the selectively energizeable magnetic surface. Upon energization of the magnetic surface, the closure element is moved from an open position in which a cross section of the charging duct is available for flow therethrough toward the cylinder to a closed position in which the energized magnetic surface retains the closure element by magnetic force at a disposition in which the closure element reduces the cross section of the charging duct in a manner which substantially prevents the flow of fluid therethrough toward the cylinder.

Abstract: In a method for opening a valve, which valve separates a flow channel from a working chamber or connects it therewith and which is embodied as a plate valve that projects upon opening into the working chamber, energy is withdrawn from a flow from the working chamber into the flow channel, resulting form the excess pressure within the working chamber upon opening movement of the valve. The withdrawn energy is used for aiding in further opening of the valve.

Abstract: An electromagnetically operating device for actuating a valve comprises a single solenoid cooperating with an armature which cooperates by a crank system with a shaft which, in turn, is cooperating by a crank system with a valve.

The armature, in the fully open position and in the closed position of the valve, is substantially in the same end position so that the crank system during a valve stroke moves through a dead center position.

A device for moving the coupling member into the coupling position and the decoupling position is provided. It has a coupling cam rotating at a same speed as the cam disk. It also has a coupling lever acting on the coupling member.
