Abstract: A rotating piston positioning device to adjust the angle of rotation of a camshaft with respect to a crankshaft of an internal combustion engine. The device includes a drive member (5) that is driven by the crankshaft and a driven member (10) that is fixed to the camshaft (4). At least the driven member (10) of the device (1) is formed of a lightweight metal and is bolted to the camshaft (4) by a central fastening screw (13), whereas the drive member (5) is radially supported external to the driven member (10) and transfers force to the driven member by at least two hydraulic pressure chambers located inside the device (1). The conical zone of force from the fastening screw (13) to the driven member (10) is carried by a special collar (16) made of a compression-resistant material that at the same time is a prefabricated pressure medium distributor of the device (1). The driven member (10) is shape-locked and/or friction locked to this collar axially, radially and circumferentially, and is bolted together with it to the camshaft (4) without deforming.

Abstract: A device for changing the control times of gas exchange valves of an internal combustion engine, particularly a rotary piston adjusting device for rotation angle adjustment of a camshaft relative to a crankshaft, which device is fastened by a central fastening screw to a camshaft mounted in the cylinder head of the internal combustion engine. The device includes a stator, in driving connection with the crankshaft and having two side covers, and of a rotor connected to rotate with the camshaft, with at least two hydraulic working spaces being formed in the stator by at least two radial boundary walls. The chambers are divided by at least two radial vanes on the rotor, respectively, into two hydraulic pressure chambers which work in opposition to one another. The stator and the one side cover of the device are formed as an integral stator unit, and the rotor and the other side cover are formed as an integral rotor unit. These are fixed together axially and radially and to the camshaft by the central fastening screw and by additional positive locking elements on the drive-side end of the camshaft or on the head of the fastening screw.

Abstract: A device for hydraulically adjusting the rotation angle of a camshaft with respect to a crankshaft of an internal combustion engine: A drive unit connected to a crankshaft and an output unit connected to a camshaft, having radially extending, axially facing sides secured by the pre-stressing force of a central securing bolt. The drive unit is rotably mounted to the output unit and they are so connected that at least two hydraulic pressure chambers transmit relative rotation forces. An annular disk with coating on opposite sides increases the frictional force between the end face of the output unit which faces the camshaft and the end of the camshaft and enables reduction of the pre-stressing force on the bolt. The character of visually detectable elements on the disk enable detection of the presence or absence of the disk.
