    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: This invention pertains to a vane-cell positioning device with an external rotor (1) driven by the crankshaft of an internal combustion engine and an internal rotor (2) fixed to and turning with a camshaft which has pivoting vanes (15) that fit inside vane mounting notches (16), said vanes being loaded with pressurized oil in hydraulic work spaces (31) of the external rotor (1). The danger of the pivoting vanes (15) lifting off of the radial sealing surfaces is eliminated by loading the bottoms of the pivoting vanes (15) with pressurized oil as the internal combustion engine is running.
