Zusammenfassung:	An oil pressure control valve housing (53) has first and second ports (59,57) connected to an oil switch (65) and reaction chamber (67) respectively. A sliding control piston (14) in the housing has first and second ring chambers (24,27) connected to each other (via 25) and communicating with the first and second ports respectively. A control piston bore (13), formed in the direction of piston movement, receives oil from the housing and accepts a pin (11), connected to or in contact with an electromagnet (52), to move the control piston.
