Control Valve, camshaft adjustment - ADT37263 BLUE PRINT

The central valve of the camshaft adjustment is located in front of the engine, and in addition, it is installed in a recess - in the place where dirt accumulates first. When the oil seal dries out or is damaged, dust and sand mixed with engine oil enter the valve channels and the working cavity of the rotary assembly. This is fraught with wedging of the electromagnetic device and accelerated wear of the chambers and blades of the phase regulator itself. In this case, excessive clearance may occur, and even damage to individual parts of the device, which is responsible for changing the valve timing.

The operation of a camshaft adjustment central valve

As soon as the BLUE PRINT brand Central Valve, camshaft adjustment is energized, the valve stem is pushed down, and oil begins to flow through other channels. Valve sticking open will be especially noticeable at idle or in low speed mode, that is, when the camshaft and gear should be in the zero position. Due to the phase shift, the intake valves close with a delay.
