    摘要： A valve timing control apparatus of an internal combustion engine includes an output element having a central bore and in mesh with an adjusting member which reciprocates between two axially spaced end positions, thereby defining two pressure compartments which are fluidly sealed from one another. An oil guide bush is received in the central bore of the output element and projects in a bore of the camshaft or the component securely fixed thereto. A first fluid passageway is formed between an outer surface area of the guide bush and an inner surface area of the driven element for conducting hydraulic medium to one of the pressure compartments, and a second passageway is formed interiorly of the guide bush for conducting hydraulic medium to the other one of the pressure compartments. The guide bush is securely fixed to a screw fastener and so configured as to allow a connection from the interior of the guide bush to the other one of the pressure compartments. By separating the unit of guide bush and screw fastener from the valve timing control apparatus, the driven element of the valve timing control apparatus now possesses only a very small axially projecting length so that no additional structural space is required between the outer and the first end wall of the cylinder head. Only after installing the apparatus together with other components of the control mechanism vertically in the form of a cartridge is the screw fastener with attached oil guide bush inserted for securement of the apparatus to the camshaft.

    摘要： The invention relates to a hydraulic camshaft adjusting device (1) of a rotary piston type that is disposed on a camshaft (3) mounted in the cylinder head (2) of an internal combustion engine and comprises a drive pinion (4) that is in driving relation with a crankshaft through a gearing (6), and a winged wheel (5) that is fixedly mounted on the camshaft (3). The drive pinion (4) is made up of a circumferential wall (7), a camshaft-distal side wall (8) and a camshaft-proximate side wall (9), which walls (7, 8, 9) together define a hollow space (10) in which at least one hydraulic working chamber is formed by at least two limiting walls (11). The winged wheel (5) comprises at least one wing (14), and each wing (14) divides a hydraulic working chamber into two hydraulic pressure chambers. In accordance with the invention, the camshaft-proximate side wall (9) of the drive pinion (4) is configured as a weight- and design space-saving thin-walled component which is shaped out of a circular blank and comprises a bent edge region (17) that is bent at a right angle and partially surrounds the circumferential wall (7) of the drive pinion (4), said camshaft-proximate side wall (9) being undetachably fixed to the drive pinion (4) by a separate connection (18).

    摘要： 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.
