    • The invention concerns a device for varying valve timing of gas exchange valves of an internal combustion engine, particularly a hydraulic camshaft adjusting device of a rotary piston type, said device comprising a drive pinion (2) connected in driving relationship to a crankshaft of the internal combustion engine and a winged wheel (3) connected rotationally fast to a camshaft of the internal combustion engine. The drive pinion (2) comprises a hollow space formed by a circumferential wall (4) and two side walls (5, 6), at least one hydraulic working chamber (10) being formed in the hollow space by at least two limiting walls (8, 9). The winged wheel (3) comprises at least one radial wing (12), and with each wing (12) it divides one hydraulic working chamber (10) into two hydraulic pressure chambers (13, 14) which, when pressurized by a hydraulic pressure medium effect a pivoting or a fixing of the winged wheel (3) relative to the drive pinion (2). When the internal combustion engine is switched off, the camshaft is rotated into a preferred basic position for starting the internal combustion engine, and in this position, the winged wheel (3) can be mechanically coupled to the drive pinion (2) by a lock. The novel lock is configured as a cage-guided free-wheel (16) arranged between the winged wheel (3) and the drive pinion (2) and comprises at least one clamping body (17) that blocks the direction of rotation of the winged wheel (3) opposed to the basic position of the camshaft. The cage (18) of the free-wheel (16) is configured at least partly as a pressure application surface (19) for the hydraulic pressure medium for unlocking the free-wheel (16).

    • A device for changing the control times of gas exchange valves of an internal combustion engine, including a drive wheel in driving connection with a crankshaft and a vane wheel connected to rotate with a camshaft. A plurality of hydraulic working spaces are formed within the device and are divided by the vanes of the vane wheel into respectively A and B pressure chambers. The vane wheel can be mechanically coupled to the drive wheel by a locking element, which is displaceable by a spring element into a locking position within a seat in one of the sidewalls of the drive wheel, and is hydraulically moved into an unlocked position in the vane wheel upon application of pressure to the pressure chambers. The locking element is a generally uniform cylindrical locking pin, and is arranged in an axial bore in the hub of the vane wheel. The longitudinal axis of the axial bore has a smallest possible distance from the longitudinal mid-axis of the device. The seat has a generally quadrilateral shaped contour that is larger by a play on all sides than the cross sectional area of the locking element, and includes a worm groove opening into it for supplying pressure medium.
