From 5000/min ("retarded")
The electromagnetic actuator (Y49) is not energized and allows the control plunger to move. The compression spring (17) pushes the control plunger
(18) against the cirdip (19). The oil feed to the working chamber "B" is closed off and oil is able to flow to working chamber "A'. along 2 drillings in
the flanged shaft (16). As a result of the engine oil pressure the control plunger (18) is moved as far as the cover (12)
This axial movement of the adjusting piston (14) rotates the camshaft (22) bolted to the flanged shaft (16) into the "retarded" position.
The rotational movement is a result of the screw effect of the helical teeth on the camshaft sprocket (13), positioning piston (14) and flanded shaft
(16). The engine oil in the working chamber (B) flows off, assisted by the pushing action of the adjusting piston (14), through 2 drillings each in the
adjusting piston (14), flanged shaft (16) and control plunger (18) through the control plunger (18) and 2 drillings in the camshaft flange (23).
Leak oil flows off over the control plunger and adjusting piston surfaces through the control plunger drilling and 2 drillings in the camshaft flange
(23).
