  • Patent number: 7861681
    Abstract: A switchable valve train for gas-exchange valves of internal combustion engines with a rocker arm device (1), in which a rocking motion about a rocker arm axis (3) can be introduced by at least one cam (2a, 2b), one tappet, or the like, wherein this rocking motion can be transmitted to at least one valve (4). The rocker arm device (1) is formed from at least one cam lever part (5) in working connection with the cam (2) and a valve lever part (6) in working connection with the valve (4), which are supported so that they can rock about the rocker arm axis (3). A coupling device is constructed between the cam lever part (5) and the valve lever part (6), in order to selectively engage and disengage the transmission of the rocking motion.

  • Publication number: 20100326383
    Abstract: An apparatus for variably adjusting control times of gas exchange valves in an internal combustion engine. The apparatus has a driving element, an output element, at least one pressure chamber, a pressurized medium supply device, and at least one pressure accumulator. The supply device allows pressurized medium to be fed to or discharged from the pressure chamber. A phase angle of the output element relative to the input element can be changed by feeding or discharging pressurized medium to or from the pressure chamber. The pressure accumulator encompasses a movable element that has a first pressure surface which partially delimits a storage space. The storage space is or can be connected to the supply device. An energy store applies a force to the movable element in the direction of an initial position. The movable element can be moved against the force of the energy store by pressurizing the storage space.

  • Publication number: 20100322545
    Abstract: A sealing arrangement for sealing rolling bearings. The sealing arrangement has a carrier ring for carrying an elastic part which has a radial sealing lip, and therefore a second ring which is movable relative to the carrier ring. The second ring has a cylindrical part provided as a radial seat for the radial sealing lip. A first installation aid is integrally formed on the radial sealing lip and prevents the radial sealing lip from becoming fixed on a second ring, such as, for example, a spinning ring, by ensuring that the radial sealing lip expands at the right time.
