20090250026 | APPARATUS FOR THE VARIABLE SETTING OF THE CONTROL TIMES OF GAS EXCHANGE VALVES OF AN INTERNAL COMBUSTION ENGINE - 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 ouput 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 ouput 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. | 10-08-2009 |
20090260589 | DEVICE FOR VARIABLY ADJUSTING THE CONTROL TIMES OF GAS-EXCHANGE VALVES OF AN INTERNAL COMBUSTION ENGINE - A device for variably adjusting the control times of gas-exchange valves of an internal combustion engine. The device has a drive input element and a drive output element, The drive input element is placed in driving connection with a crankshaft of the internal combustion engine, the drive output element is arranged so as to be pivotable with respect to the drive input element, and the device is fastened to a camshaft which has a hollow shaft and an inner shaft which is arranged concentrically with respect to the hollow shaft. An improved mounting arrangement of the concentrically arranged shafts with respect to one another is proposed. | 10-22-2009 |

20100199936 | TIMING ADJUSTMENT DEVICE FOR AN INTERNAL COMBUSTION ENGINE - A timing adjustment device with axially joined components, clamped by a camshaft central screw on a hub element which maintains the required peripheral position of these components relative to one another within a narrow tolerance range. On a disk element of the timing adjustment device an insert section is formed, which can be inserted into a recess formed in the hub element and, in the region of the insert section, at least one anchoring structure is formed, through which the insert section is anchored on a counter-structure, which is provided by the hub element. | 08-12-2010 |
20100218737 | CONTROL TIME ADJUSTING DEVICE - A control time adjusting device which adjusts the phase position of a camshaft with respect to an upstream drivetrain that drives the camshaft. The device has a hub element and a bell element which is coupled to the hub element in a variably adjustable manner with regard to the rotary phase position. The adjusting angle range is defined by stop structures. Additionally, adjusting cells, which are separated by radial webs and vane elements, are situated in an intermediate space between the hub element and bell element. The position and the peripheral length of the device, which is definitive for the pivoting travel of the adjusting cells and the arrangement of the vane elements with respect to one another, are adapted such that at least two different-sized adjusting angle ranges can be defined as a function of the assignment of the vane elements to the adjusting cells. | 09-02-2010 |
20110067655 | DEVICE FOR VARYING THE ANGULAR POSITION OF A CAMSHAFT RELATIVE TO A CRANKSHAFT OF AN INTERNAL COMBUSTION ENGINE - A device for varying the angular position of a camshaft relative to a crankshaft of an internal combustion engine. The device has a drive element, which is driven by the crankshaft via a gearwheel and which is supported so that it can rotate in relation to the camshaft. The device also has at least two hydraulic chambers, to which a hydraulic fluid can be admitted in order to set a defined relative rotational position between the drive element and the camshaft, formed between the drive element and the camshaft. In order to produce an optimum axial support of the camshaft in terms of weight and cost, the gearwheel form a bearing face for the axial contact of the camshaft or of a component rotationally fixed to the latter. | 03-24-2011 |

20130199479 | ROTOR FOR A CAMSHAFT PHASER, AND CAMSHAFT PHASER - A rotor for a camshaft phaser includes a hub part having an oil supply passage, at least one vane radially disposed on the hub part, as well as oil channels extending through the hub part and fluidically connected to the oil supply passage. The manufacture of the rotor is considerably simplified because the rotor is made up of a main body and at least one cover element arranged on an end face of the main body. The oil channels are axially closed by the cover element. | 08-08-2013 |
