Abstract

A valve control system may include an adjustable camshaft that includes an outer shaft and an inner shaft that extends through the outer shaft. The valve control system may further include a phase shifter that comprises a first control element and a second control element that can be rotated relative to the first control element. The outer shaft and the inner shaft may each be connected with a control element. The valve control system may also include a stop coupled with the outer shaft in a torque-proof manner, as well as a counter-stop coupled with the inner shaft in a torque-proof manner. A maximal angle of rotation of the inner shaft in the outer shaft may be determined by the stop bordering on the counter-stop.
