  • Patent number: 11300016
    Abstract: A valve opening and closing timing control device includes a drive-side rotating body that rotates synchronously with a crankshaft of an internal combustion engine, a driven-side rotating body that rotates with a camshaft of the internal combustion engine, an electric motor that controls a relative rotation phase of the drive-side rotating body and the driven-side rotating body, a motor control unit that controls a current supplied to the electric motor, a current sensor that detects the current flowing into the electric motor, a regulation unit that determines a regulation phase in which the relative rotation phase is mechanically limited in an advanced angle direction and in a delayed angle direction, and a regulation phase detection unit that detects the regulation phase based on when the relative rotation phase in which a change is stopped by the regulation unit is reached and a current value detected by the current sensor increases.

  • Patent number: 10738716
    Abstract: A valve timing controller includes: a driving side rotation member that rotates synchronously with a crankshaft of an internal combustion engine; a driven side rotation member that integrally rotates with a cam shaft of the internal combustion engine; a phase regulating mechanism with which a relative rotation phase of the driving and driven side rotation members around a rotation axis is set by a driving force of an electric motor; a phase sensing portion that acquires the relative rotation phase; and a phase controlling section that controls the electric motor to set the relative rotation phase based on an acquisition result by the phase sensing portion. The phase sensing portion includes a cam angle sensor, a reference determination sensor, and a pattern storage unit. The valve timing controller further includes a phase acquisition portion.

  • Patent number: 10711656
    Abstract: A control apparatus of a valve opening/closing timing control mechanism, configured by including driving side and driven side rotating bodies; a stopper unit; and an electric motor, includes: a phase controller controlling an electric motor to reduce, when a target phase is set, a deviation between the target phase and a current first actual phase and reducing power to be supplied to the electric motor as the deviation decreases; and a control target setting unit setting a first target phase displaced to a side of the first actual phase in an operation direction where the deviation is reduced when the target phase is set to a most retarded or most advanced angle phase, in which the phase controller executes a first phase control of reducing a deviation between the set first target phase and the current first actual phase.

  • Patent number: 4415221
    Abstract: A female type electrical connector produced by stamping and bending of thin sheet metal including a receptacle section and a wire connection connected to the rear end of the receptacle section. The receptacle section includes a tongue extending from the front end thereof and formed with a locking projection on its upper surface, and being pivotable on its front end for resiliently moving downwardly, and two side walls each having a curved wall. The curved walls of the side walls extend from outside the opposite side edges of the tongue and are curved upwardly to extend above the tongue, and terminating at free ends which extend longitudinally and are juxtaposed to the upper surface of the tongue. The locking projection engages a projection receiving portion of a male electrical connector to lock the latter in place when the male type electrical connector is inserted between the upper surface of the tongue and the free ends of the two side walls and held therebetween.
