Device for variable adjustment of control times of gas exchange valves of lifting cylinder combustion engine, has control unit arranged in sleeve, where sleeve is connected with camshaft, positioning device and/or attachment element

摘要

The device has a hydraulic phase positioning device provided at a driving end of a crankshaft, where an output-side of the positioning device is in active connection with a camshaft of a lifting cylinder combustion engine. A valve unit (3) hydraulically controls a phase positioning device. The valve unit is controlled by a control actuator on a camshaft side facing away from a control head (6). A control unit is arranged in a threaded sleeve (1), where the sleeve is connected with the camshaft and/or the phase positioning device and/or an attachment element.
