A hydraulic camshaft adjuster () including a stator () and a rotor () arranged such that it can rotate relative thereto, the stator () being connected to at least one separate cover () that seals a cavity () located between the rotor () and the stator (). In the region of the cover (), the material of the stator () at least partially encompassing said cover () is formed without machining.

Camshaft adjuster with a rolled connection

A camshaft phaser () having a stator () and a rotor (), whereby at least one cover () is attached to the stator () by means of at least one screw () that has a head (), whereby a spring () is joined to the rotor () and to the screw () so as to transmit force, whereby the spring () is in contact with a pin () that has a polygonal outside shape and that extends lengthenwise from the head () of the screw ().

Camshaft phaser having a spring attached to the pin of a screw

An apparatus for variable setting of control times of gas exchange valves of an internal combustion engine which has a drive element, an output element and a side cover. The drive element is brought into drive connection with a crankshaft, the output element is brought into drive connection with a camshaft, and the output element is arranged such that it can be pivoted with respect to the drive element. The side cover, which has a sealing cover with an opening and a mating element, axially delimits the output element and/or the drive element, and is connected in a rotationally fixed manner to the drive or output element by means of a fastening element. The fastening element reaches at least partially through the opening and interacts with the fastening element producing a rotationally fixed connection between the side cover and output element or drive element.

An apparatus for variable setting of control times of gas exchange valves of an internal combustion engine which has a drive element an output element and a side cover. The drive element is brought into drive connection with a crankshaft, the output element is brought into drive connection with a camshaft, and the output element is arranged such that it can be pivoted with respect to the drive element. The side cover, which has a sealing cover with an opening and a mating element, axially delimits the output element and/or the drive element, and is connected in a rotationally fixed manner to the drive or output element by means of a fastening element. The fastening element reaches at least partially through the opening and interacts with the fastening element producing a rotationally fixed connection between the side cover and output element or drive element.

A device () for controlling and/or influencing the valve control times of an internal combustion engine, in particular to a camshaft adjustment device, which includes a drive element () which is fastened to an attachment part () with a screw connection (), wherein the drive element () and/or the attachment part () are/is composed of a fiber-reinforced material. In order to obtain a more lightweight design and to be able to reduce screwing forces, the invention provides that at least one of the contact faces () between the drive element () and the attachment part () is at least partially subjected to material-removing processing.
