    摘要: A hydraulic apparatus for adjusting the timing of opening and closing of an engine valve includes a cam shaft driven to rotate in synchronization with the engine rotation. An actuator is installed on the cam shaft for changing the timing of opening and closing of an intake valve and/or exhaust valve using a control of a working oil supply. A slidable plunger is disposed in the actuator, and a rotor is disposed in the actuator to engage with the plunger by an engaging hole. A spring urges the plunger to move into the engaging hole to make an engagement therebetween when the engine is stopped, and when the engine begins to run, the working oil is supplied into the engaging hole to push out the plunger from the engaging hole to release the engagement between a housing of the actuator and the rotor. The engaging hole and the plunger have a surface parallel with a slide direction of the plunger, and a clearance therebetween is smaller than 0.17 mm when the engaging hole and plunger engage each other.

    摘要: A valve lift control device includes an inner tappet biased toward a low-lift cam pertinent to the opening and the closing of a valve in a low-lift mode acting as one of cams which are arranged on a camshaft being driven rotationally in synchronization with a rotation of an internal combustion engine; an outer tappet arranged outside of the inner tappet and biased toward a high-lift cam pertinent to the opening and the closing of the valve in a high-lift mode among the plurality of cams; and a rotational member being arranged rotationally in a peripheral direction of the inner and outer tappets and including at least one projection member being outwardly projected from a perimeter of the inner tappet and an engagement section engaging with the projection member. The valve lift control device blocks or allows a relative sliding of the inner and outer tappets in an axial direction of the tappet due to rotation of the rotational member in a required range.

    摘要: The vane type hydraulic actuator according to the present invention comprises a guide locking mechanism (guide stopper pin) (1) for guiding the rotor (44) to a locking position where the rotor (44) can be locked to the case (43), and a retaining locking mechanism (retaining stopper pin) (4) for retaining the rotor (44) to the case (43), after the rotor (44) is guided to the locking position. The actuator having vanes, wherein the length in the peripheral direction of the tip portion of the vane having the locking mechanism is substantially identical to that of the vane which is located symmetrically thereto. The length in the peripheral direction of the tip portion of the other vanes is shorter than that of the vane having the locking mechanism.
