摘要： The invention relates to a device for adjusting the angle of rotation of a camshaft of an internal combustion engine relative to a drive wheel. Said device comprises an inner part (4) that is linked with the camshaft in a rotationally fixed manner and that has at least substantially radially extending webs or blades (6a to 6e). A driven cellular wheel (10) is provided with a plurality of cells distributed across its periphery and delimited by webs (12a to 12e). Said cells are subdivided into two respective pressure compartments (22a to 22e and 24a to 24e) by the webs or blades (6a to 6e) of the inner part (4) that are guided inside said cells in an angularly mobile manner. When the pressure compartments are hydraulically pressurized or depressurized via control lines, the camshaft can be rotated between two end positions relative to the cellular wheel (10) by way of the webs or blades. Sealing elements (40) are disposed on the free front face (36) of the webs or blades and seal the pressure compartments defined by said webs or blades. The device is further characterized in that the front face (36) of the webs or blades (6a to 6e) is provided with recesses (38) in which sealing bodies (40) are disposed that are forced against an internal wall (42) of the cellular wheel (10) by a hydraulically applied force. The sealing bodies are configured as rollers (40) that are received in recesses (38) with a certain assembly clearance. Said rollers (40), during operation of the adjustment unit (5), establish a linear contact (LK1, LK1") with the internal wall (42) of the cellular wheel (10) and a linear contact (LK2, LK2") with the side walls (44, 44") of the recesses (40), thereby sealing the pressure compartments.

摘要： The inventive device for changing the relative rotational position of a shaft to the drive wheel has an adjustment device with two counter-acting pressure chambers, which are impinged upon by a hydraulic pump. In order to achieve an evenly regulated adjustment procedure and to reliably fix the position, the pressure chamber that is connected to the hydraulic pump is impinged upon by pressure at the beginning of the adjustment movement before the opposite pressure chamber attached to the hydraulic tank is relieved.

摘要： The invention relates to a device for adjusting the angle of rotation of the camshaft (1) of an internal combustion engine in relation to its driving wheel. The device essentially consists of an inner part (2) which is provided with webs (4a to 4d) or blades and which is arranged in a cell wheel (5) in such a way that it can rotate. This driven cell wheel (5) has several webs (6a to 6d) arranged around the periphery, each of which are divided into two pressure chambers (7a to 7d, 8a to 8d) by the webs (4a to 4d) or blades of the inner part (2). Subjecting the pressure chambers to pressure or relieving them of pressure causes the angle of rotation to change. As the shaft approaches its final position, the displacement is hydraulically dampened by integrated damping elements. Said damping elements are formed by the interaction of the webs (4a to 4d, 6a to 6d) of the inner part (2) and the cell wheel (5) as they approach each other.

摘要： The invention relates to an internal combustion engine with a cylinder head and at least one camshaft (74) mounted on said cylinder head. Said camshaft is driven by a crankshaft and actuates corresponding gas exchange valves on the cylinder head. A camshaft adjuster (76) is provided on the camshaft (74) which twists the camshaft (74) relative to the crankshaft so as to change the control intervals of the gas exchange valves by means of hydraulic pressure, a feed device for hydraulic pressure being provided on the camshaft adjuster (76). The feed device for the hydraulic pressure is configured as a component (10) separate from the cylinder head that comprises one ring (13) for each camshaft (74) which encircles a section of the camshaft (74). Each ring (13) has two grooves and the respective encircled section of the camshaft (74) has two annular grooves (82, 84) that are aligned with respective grooves of the corresponding ring (13). Every groove/annular groove pair (82, 84) of a ring (13) is linked with the hydraulic pressure chamber (88, 92) of the camshaft adjuster (76) mounted on said camshaft (74) via hydraulic pressure channels (86, 90) within the camshaft (74). Every groove/annular groove pair (82, 84) of a ring (13) is linked with a hydraulic pressure valve (62, 64) via respective hydraulic pressure channels (44, 46, 48 or 56) in the feed device (10).
