Abstract: The sensor unit for a sensor/transmitter system is used to capture at least rotational and linear movements of a component (1) having magnetic poles. The sensor unit has at least one sensor which is at least one electrically conductive conductor bar (5) which is transverse with respect to the direction of movement of a magnetic field of the component (1). The relative movement between the magnetic field and the conductor bar (5) produces a voltage at said conductor bar, which voltage can be supplied to evaluation electronics (4).

Abstract: The present invention relates to a method and an arrangement for determining the armature (1) position of an electromagnet. In the method the potential differences in the yoke (2) or in the armature (1), generated by a non-homogeneous eddy current distribution in the event of a deflection of the armature (1), are detected to determine the instantaneous armature (1) position relative to a reference position from these potential differences. For this purpose at least one voltage difference is measured between two measuring points on the yoke (2) or armature (1), or between one measuring point on the yoke (2) or armature (1) and a reference potential. The armature (1) position relative to a reference position on the electromagnet is then determined from this voltage difference. The method can be performed cost effectively, and can also easily be applied to existing electromagnets.

Abstract: A method for controlling the opening of at least one intake valve of a combustion chamber in a periodically working piston engine, at least one intake valve of the combustion chamber being opened during a first partial period of a working period of the piston engine for charging the combustion chamber; and at least one intake valve of the combustion chamber being opened during a second partial period of the working period, wherein the second partial period begins after the combustion of the combustion chamber charge and has no overlap with the first partial period.

Abstract: Disclosed is a simple, easy-to-produce, and reliable connection between a shaft of a gas exchange valve and an actuator. This connection is detachable and, as a result, can be connected and disconnected multiple times. It is also possible to dispose the coupling piece on the shaft of the gas exchange valve and provide circumferential grooves on the control element of the actuator.

Abstract: The present invention relates to a connection between a shaft end of a gas exchange valve of an internal combustion engine and a sleeve-shaped actuating element of a valve actuator, which is guided in an axially movable manner within a pressure region, which is able to be pressurized with a pressure medium, of the valve actuator and at least partially surrounds the shaft end. The present invention provides for the connection to be situated outside of the pressure region and in the region of an opening, which is formed on the side of the valve actuator away from the combustion chamber, and is, for example, coaxial to the shaft end.

Abstract: An electrohydraulic valve control (10) of an internal combustion engine includes at least one actuator (24) that acts on a gas exchange valve (38). This actuator (24) in turn has at least one working chamber (30), which in order to switch the actuator (24) from a first position into a second position, is connected to a high-pressure hydraulic accumulator (16) and shut off from a low-pressure return (56). In order to switch the actuator (24) from the second position back into the first position, the working chamber (30) is connected to the low-pressure return (56) and shut off from the high-pressure hydraulic accumulator (16). The pressure in the high-pressure hydraulic accumulator (16) is kept constant or reduced in a simple manner by virtue of the working chamber (30) being connected to the high-pressure hydraulic accumulator (16) and the low-pressure return (56) at the same time.

Abstract: A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided.

Abstract: A fuel injector, particularly an injector for a fuel injection system of an internal combustion engine, includes a piezoelectric or magnetostrictive actuator and a valve closure member which is actuable by the actuator with the aid of a valve needle and which is cooperable with a valve-seat surface to form a sealing seat. An electromagnetic damping device is provided for damping the movement of the valve needle.

Abstract: A method and a device for driving at least one solenoid valve used for controlling the injection of fuel into an internal combustion engine. At the start of the driving (activation), the solenoid valve is supplied with a booster voltage that is elevated as compared to that used for the further driving. The energy and/or power output received by the solenoid valve at the start of the driving is able to be influenced as a function of the operating state of the internal combustion engine.
