20090188453 | DEVICE FOR SETTING THE RELATIVE ROTATIONAL POSITION OF A CAMSHAFT OF AN INTERNAL COMBUSTION ENGINE RELATIVE TO A CRANKSHAFT DRIVING THE CAMSHAFT - A device for setting the relative rotational position of a camshaft ( | 07-30-2009 |
20100037841 | 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 an outer and inner rotor rotatable relative to the former, with one component drive-connected to a crankshaft and the other drive-connected to a camshaft. The apparatus has at least one pressure space, which are each divided into two pressure chambers acting counter to one another. The apparatus has a plurality of pressure medium channels, via which pressure medium is fed to or led away from the pressure chambers. Additionally, the apparatus has a plurality of rotational-angle limitation devices assuming an unlocked and locked state. The locking states are set by the supply of pressure medium to or discharge of pressure medium from the respective rotational-angle limitation apparatus. Furthermore, a method for controlling an apparatus for variable setting of control times of gas exchange valves of an internal combustion engine is disclosed. | 02-18-2010 |
20100242876 | MODULAR CONSTRUCTION CAMSHAFT ADJUSTER WITH A CHAIN OR BELT WHEEL - A modular construction camshaft adjuster for the camshaft drive of an internal combustion engine with a chain or belt wheel, which has at least one wheel rim facing radially outwards with tooth engagement recesses, an annular wheel plate around a central circular opening and an essentially cylindrical wheel wall with a wall thickness, projecting in an axial direction from the annular wheel plate, such that the wheel wall and the wheel plate together form a cup shape. The minimum wall thickness of the essentially cylindrical wheel wall beneath the at least one wheel is equal to half the tooth engagement recess and the cup-shaped chain or belt wheel is made from a lightweight material. | 09-30-2010 |
20110139101 | CAMSHAFT ADJUSTER - A camshaft adjuster for adjusting the phase position of a camshaft relative to a crankshaft, in particular a hydraulic camshaft adjuster. A camshaft bearing area provided in the camshaft adjuster is designed as a roller bearing. | 06-16-2011 |
20130000580 | INTERNAL COMBUSTION ENGINE HAVING A DEVICE FOR CHANGING THE RELATIVE ANGULAR POSITION OF A CAMSHAFT WITH RESPECT TO A CRANKSHAFT - An internal combustion engine ( | 01-03-2013 |
20150144082 | RADIAL CAMSHAFT PRESSURE MEDIUM TRANSFER - A camshaft unit includes a camshaft having a radial channel, a hydraulic phase setting device communicating with the radial channel for adjusting the phase length of the camshaft with respect to a crankshaft via hydraulic pressure medium and a pressure medium channel embodied as a solid cylinder head component. To transfer a pressure medium, at least one pressure medium transfer element is formed between the pressure medium channel and the radial channel. The pressure medium transfer element includes a ring channel including a ring channel opening extending in the peripheral direction of the ring channel and including a radial channel opening leading into a radial channel and opposite the ring channel opening. The pressure medium channel communicates with the radial channel via the ring channel opening and the radial channel opening. | 05-28-2015 |
