摘要： A device for variable adjustment of the timing of gas exchange valves of an internal combustion engine, which has a hydraulic phase shifting device, a camshaft and a pressurizing medium distributor. The phase shifting device can come into drive linkage with a crankshaft and is rigidly connected to the camshaft. A phase position of the camshaft relative to the crankshaft can be variably adjusted by the phase shifting device. The interior of the camshaft has a cavity that communicates with one or more camshaft bearings which are separate from a rotating pressurizing medium conveyor. The pressurizing medium distributor is disposed in a receiving area of the camshaft. The camshaft has an opening in the area of the pressurizing medium distributor, which communicates with the interior of the camshaft and the pressurizing medium conveyor. A pressurizing medium path is inside the camshaft, which communicates the opening and hydraulic phase shift device.

摘要： A motor control strategy for a hydraulic camshaft adjuster. The motor control strategy has a mechanical central lock which in turn has at least one rotor and one stator, between which hydraulically loadable chamber A and chambers B are provided. Locking pistons supported in an axially displaceable manner are provided in the rotor for the mechanical central lock. A hydraulic system and an electrically controllable solenoid valve are provided The valve is powered in a controlled manner by a motor control device, which receives an “ignition off” signal; the motor being turned off, and at least one signal for current angular position of the camshaft adjuster, which compares the angular position to at least one zone definition stored in the motor control device, forms control commands from the same, and transmits the control commands to the electric solenoid valve.

摘要： A device for variably adjusting the control times of gas exchange valves of an internal combustion engine. The device has a driving element, an output element, at least one pressure chamber, at least one mechanism limiting the angle of rotation, and a pressure accumulator. A phase angle between the output and driving element is changed by delivering or discharging pressure medium to or from the pressure chambers. The mechanism limiting the angle of rotation has a receiving member and an engaging element to which a force is applied towards the receiving member (45). When locked, where the engaging element engages into the receiving member, the mechanism limiting the angle of rotation limits the phase angle of the output element relative to the driving element at least to an angular spread. The mechanism limiting the angle of rotation can be unlocked by applying pressure medium to the receiving member.

摘要： A device for camshaft adjustment in an internal combustion engine which has an inner rotor rotationally fixed to a camshaft. The inner rotor is rotationally adjustable relative to an outer rotor that is driveably connected to a crankshaft. At least one hydraulic chamber limited by side walls is introduced into the outer rotor and is divided into two partial chambers by an element extending radially outward from the inner rotor. To lock the relative movement between the inner and outer rotor, two locking pins penetrating the inner rotor axially engage in two recesses of one of the side walls designed as a locking cover. To adjust the play of the locking pins in the recesses, at least one of the recesses has a stop surface for the locking pin, the position of which changes as viewed circumferentially with the radial distance from the axis of the inner rotor.
