Abstract: Apparatus for adjusting the basic position of a camshaft adjustment unit of an internal combustion engine, includes a first structure secured to a crankshaft and a second structure secured to a camshaft and having a camshaft-distant end surface formed with one or more form-fitting and/or force-locking force-transmitting elements. A piston reciprocates between two end positions and is so operatively connected with the first and second structures that a displacement of the piston results in a rotation of the first and second structures relative to one another. In order to position the adjustment unit in the basic position and to prevent the adjustment unit from executing a rotation relative to the camshaft after occupying the basic position, a tool is attachable to the adjustment unit which tool is formed with counterelements which complement the force-transmitting elements to effect a non-rotatable connection between the tool and the adjustment unit.

Abstract: A valve characteristic control apparatus is provided with a simple structure in which a cam shaft having three-dimensional cams is axially displaced and the cam shaft is rotated with respect to a crank shaft by a ring gear. An axial driving mechanism axially displaces the intake cam shaft and thereby changes working angles of the three-dimensional cams. In this case, engagement of a spline formed on the cam shaft with teeth formed on an inner peripheral surface of the ring gear allows the cam shaft to axially move with respect to a pulley integrated with the crank shaft. A rotational driving mechanism axially displaces the ring gear, so that a helical spline formed on the pulley engages teeth formed on an outer peripheral surface of the ring gear and a spline formed on the cam shaft engages teeth formed on the inner peripheral surface of the ring gear. Thus, the cam shaft rotates relative to the pulley.

Abstract: According to the present invention, in a valve timing adjustment device, an arc-shaped gears are assembled alternately on a piston in the peripheral direction. A spring biases an annular member and the arc-shaped gear in the direction as to be away from the piston. A pin is press-fitted into a retainer ring. A spring biases the arc-shaped gear toward the retainer ring, that is, in the direction as to be closer to the piston. An annular member, an annular groove, the head of the pin, a cap, and a containing hole function as a hydraulic damper, respectively. Accordingly, the collision speed of the annular member with the piston accompanied by the movement of the arc-shaped gears, and the piston and the collision speed of the head of the pin with the piston are slowed down. In this way, the respective collision noises can be reduced.
