Device for controlling gas exchange in four-stroke internal combustion engine, comprises crank that is mounted at cylinder cover side facing away from combustion chamber, which is driven with transmission unit by crankshaft

摘要

The device comprises a crank (2) that is mounted at a cylinder cover side facing away from a combustion chamber, which is driven by with a transmission unit by a crankshaft, and a toothing, which transmits the relative rotational movement of a pick-up lever (3) opposite to the crank of a gear that is connected to a hollow shaft in a fixed manner. A control element is provided, which is a hollow cone, whose shell surface are broken into segment shaped. Independent claims are also included for the following: (1) a highly positive locking cam joint element for a device for controlling the gas exchange in a four-stroke internal combustion engine; and (2) a groove or web cam disk for a device for controlling the gas exchange in a four-stroke internal combustion engine.
