20110232402 | ADJUSTMENT DEVICE FOR ADJUSTING A RELATIVE ROTATIONAL ANGLE POSITION OF TWO SHAFTS AND METHOD FOR OPERATING AN ACTUATOR, PARTICULARLY OF SUCH AN ADJUSTMENT DEVICE - An adjustment device for adjusting a relative rotational angle position of two shafts (particularly a cam shaft and a crank shaft of an internal combustion engine) that has an adjusting gear which is designed as triple shaft gear and has a drive part connected to a first shaft (crank shaft), a driven part connected to a second shaft (cam shaft), and an adjustment shaft connected to a servomotor shaft of an electric servomotor in a rotationally fixed manner. In order to implement a wide temperature range for the operation of the adjustment device, a temperature sensor is arranged in the servomotor. In a method for operating an adjustment device or an actuator, the current of the servomotor or the actuator is controlled depending on the temperature that was determined earlier. | 09-29-2011 |

20130199474 | NON-RETURN VALVE OF A CAMSHAFT ADJUSTER - A camshaft adjuster with a drive element, a driven element, and a pressure chamber formed between the drive element and the driven element for generating a relative rotation between the driven element and the drive element, and a volume accumulator that is arranged in the camshaft adjuster and supplies hydraulic medium via a channel from the volume accumulator to the pressure chamber if there is an under-pressure in the pressure chamber. The camshaft adjuster has a non-return valve with a closing part for closing an opening of the channel, the non-return valve allows a flow of hydraulic medium through the channel from the volume accumulator to the pressure chamber, and there is an elastically expandable component that projects into the channel and can be guided by the channel and is connected to the closing part and is provided for applying tension for pulling the closing part into the channel. | 08-08-2013 |
