摘要： A hydraulic camshaft-adjusting device of the rotary piston type that includes of a drive gear (2) directly connected to a crankshaft and an impeller that is directly connected to a camshaft (3). The drive gear (2) has a cavity formed from a perimeter wall (5) and two side walls (5, 6) inside of which at least one hydraulic working chamber is formed from at least two boundary walls. The impeller has at least one radial vane (12) and each vane (12) divides one hydraulic work chamber into two hydraulic pressure chambers. The outer end (18) of each vane (12) of the impeller is pressed radially against the perimeter wall (5) of the drive gear (2) as a result of the force of a spring element (17) located at the inner end (15) of the vane. The spring elements (17) located at the inner end (15) of the vanes (12) have, at unchanged space requirements, a spring force that is greater than the pressure force of the hydraulic pressure medium acting on the outer end (18) of the vanes (12) in the respective actuated pressure chamber of the device (1).

摘要： The invention relates to a locking unit for a device for modifying the timing of charge change valves of an internal combustion engine, especially for a vane-cell control device. Said device (1) comprises a drive wheel (3) presenting a hollow space (8) and connected to a crankshaft of the internal combustion engine in a driving manner. The device also comprises an impeller (9) which has at least one vane (13) and is connected to the camshaft (2) in a non-rotating manner. At least one working chamber (20), which is divided by a vane (13) into two hydraulic pressure chambers (21, 22), is formed by intermediate walls (16) in the hollow space (8) of the drive wheel (3). When the pressure chambers (21, 22) are subjected to pressure by means of a hydraulic pressure medium they cause the impeller (9) to pivot in relation to the drive wheel (3). When there is no pressure in one of the two pressure chambers (21, 22) the impeller (9) and the drive wheel (3) are mechanically coupled to each other. According to the invention the mechanical coupling between the impeller (9) and the drive wheel (3) of the device (1) can be achieved by means of at least one radially movable vane (13) of the impeller (9) which is configured as both an impeller pivoting element and a locking element.

摘要： In an internal combustion engine with two camshafts arranged next to one another and each mounted in a radial bearing in the cylinder head and hydraulic device for rotary angle adjustment of each camshaft with respect to a crankshaft. The supply and discharge of hydraulic pressure medium to and from the devices are controlled separately in each case by an electromagnetic hydraulic valve comprised of an electromagnet and of a valve housing capable of being plugged into a valve receptacle. Each valve housing on its circumference has a plurality of annular grooves with a plurality of radial orifices and on its free end face has a further orifice, via which the hydraulic valves are fluidically connected to the radial bearings of the camshafts and to a pressure connection and to a tank connection. Valve receptacles are passage bores which are fluidically connected via horizontal transverse ducts to the radial bearings of the camshafts and to the pressure connection. The separation of individual fluid streams is caused by an adapter sleeve plugged axially onto each valve housing and having a plurality of radial bores.
