Abstract:
a cam adjuster for adjusting the angle-of-rotation positions of a cam shaft relative to a crankshaft. The cam shaft adjuster has at least two operating chambers to which pressure oil can be supplied to change the angle-of-rotation position. At least one of the operating chambers can be deactivated depending on an operating parameter by blocking the pressure oil supply.
