摘要： A variable valve controller for internal combustion engines and methods for operating the same. In the variable valve controller, and engine control unit (ECM) calculates a target value of a valve lift (VEL) for an intake valve and transmits it to a controller with a second control unit (VEL-C/U). The VEL-C/U controls the VEL on the basis of the VEL target value, detects a VEL actual value, and transmits it to the ECM. The ECM calculates a target value of a valve timing (VTC), and controls the VTC. Also, the ECM controls a limit value for the VTC target value in accordance with the VEL actual value. Fail-safe control is performed when an error occurs in a communication unit or a sensor. To reliably perform the control in a period from occurrence of an error to detection of the error, the limit value is set with calculation by offsetting a limit basic value set in accordance with the VEL actual value, by a displacement of the VEL within a time necessary for detecting the error.

摘要： A hydraulic control valve has a solenoid body, a selectively energizable coil, and an armature positioned adjacent the coil. The coil is energizable to generate a magnetic force that moves the armature from a first position to a second position. A pole piece is positioned to establish a gap between the pole piece and the armature. The pole piece has a cavity that opens at the gap. A piston extends from the armature into the cavity and moves with the armature. The armature is biased to seat at a valve seat in the first position by pressurized fluid. Magnetic force required to move the armature away from the valve seat is a function of the difference between an area of the piston and an area defined by contact of the armature at the valve seat.
