Abstract: A device allows the phase position between two shafts in driving relationship to be continuously adjusted. A two-position adjustment is known, having a piston upon both sides of which a pressurized medium can be applied and whose axial displacement causes at the same time an angular shifting between the rotation positions of the shafts in driving relationship. The object of the invention is to create a continuous adjustment device which can be mounted in the available space, and in which the pressurized medium can reach the adjusting element without affecting adjacent part. In the disclosed adjusting element (4), the pressurized medium reaches a rotary bushing (13) through a fixed connection plate (8a, 8b), and from there it is at first axially and then radially led into the pressure chambers (11, 12).

Abstract: A phase adjustment mechanism for setting the phase of the engine camshaft (14) relative to that of the crankshaft (12). The operative coupling of the crankshaft to the camshaft is via two sets of splines, one set having pitch different from that of the other set. A spline engagement ring (32) contains a spline of one set (36, 38) on its O.D. and a spline of the other set (30, 34) on its I.D.. The axial positioning of the ring (32) controls the relative phasing and is accomplished by a screw (50) and nut (52) mechanism with the nut (52) being operated by a worm drive (60) that is under the control of the engine ECU (64).

Abstract: A cam phase adjustor (10) for an internal combustion engine includes a drive gear (11), an index gear (15), an actuator (14) and a camshaft (17). Actuator (14) is rotated and moves linearly to reciprocate the index gear (15) in response to engine rpm changes. Linear movement of the index gear (15), which serves as the drive link between the drive gear (11) and the camshaft (17), causes relative rotational motion between the spinning index gear (15) and camshaft (17), thus changing the angular phase of the camshaft (17) relative to the drive gear (11). This is used to advance or retard the opening and closing of the intake and/or exhaust valves of an internal combustion engine to improve engine performance over a wide range of operative engine speeds. Linear and rotational movements of the components are facilitated, for example, by cooperating grooves (31, 33 and 62, 56) and balls (34 and 63) in the respective components so there is rolling rather than sliding motion between the components.

Abstract: In a device (1) for modifying the opening and closing times of gas exchange valves of an internal combustion engine, high-frequency knocking of the regulating piston at one of its end positions when the engine is started again is to be avoided by simple means. For this purpose, a slide (18) secured against rotation in relation to a section (19) of the housing connected to a driving wheel (2) is mounted in one of the pressure chambers (15, 16). This slide (18) can be positively coupled to a driven unit (12) by the force of a compression spring, against the falling pressure of the hydraulic medium. This prevents the regulating piston (8) from moving further in the axial direction immediately after the internal combustion engine is started and until the device (1) is filled again with hydraulic medium, thus preventing the high-frequency knocking of the piston at its corresponding end position.

Abstract: The device proposed enables the rotational position of e.g. a cam shaft (2) to be continuously adjusted relative to the crankshaft driving it in order to modify the control reaction times in an internal-combustion engine. The device comprises an intermediate gear wheel (7) which moves axially between two extreme positions and which meshes by means of helical outer and inner toothing (6, 10) with a drive pinion (4) and the cam shaft (2). An annular space (17) in a stationary ring bearing (16) is filled with an electroviscous fluid which, on application of a voltage by an electronic control unit (30), produces a force acting to displace the intermediate gear wheel (7). An electroviscous locking bearing (21) between the cam shaft (2) and the intermediate gear wheel (7) holds the intermediate gear wheel (7) in any position between its two extreme positions (E1, E2).
