Abstract

A camshaft may have an inner shaft and an outer shaft, each rotatable relative to the other. An adjusting device may include a first phase adjuster and a second phase adjuster. The outer shaft may be mounted in a stationary counter bearing adjacent to the adjusting device and the adjusting device may have a first phase adjuster and a second phase adjuster. The counter bearing may be designed as a slide bearing and oil supply to the phase adjusters may take place via the slide bearing. The slide bearing may have a first, second and third oil channel. The first oil channel may act on the first phase adjuster with corresponding oil flows, the second oil channel may act on the second phase adjuster with a first oil flow, and the third oil channel may act on the second phase adjuster with a second oil flow.
