Abstract: A device (1) for modifying the control times of an internal combustion engine (100) is provided, including a drive gear (13), a driven element (4) and a swashplate mechanism (2). The torque of the crankshaft (101) is transferred via a primary drive to the drive gear (13), and via the swashplate mechanism (2) to the driven element (4) which is connected in a rotationally fixed manner to the camshaft (11). The drive gear (13) can be rotated in relation to the driven element (4) via the swashplate mechanism (2), whereby a continuous phase modification of the camshaft (11) relative to the crankshaft is possible. According to the invention, foreign body collecting pockets (33) are provided in the housing of the swashplate mechanism (2), wherein foreign substances entering into the lubricant can be collected.

Abstract: In a valve timing controller, the guide-groove biases the moving element in a direction in which the moving element slides with respect to a radial line connecting a center of the guide-rotational element and the moving element, when the guide-rotational element relatively rotates with respect to the first rotational element. The direction in which the moving elements are pushed and the direction in which the moving elements moves are substantially identical to each other.

Abstract: In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

Abstract: A device for varying valve timing in an internal combustion engine comprises an adjusting mechanism for varying an angle of rotation between a drive pinion (2) and a camshaft (end portion of the camshaft 1), said adjusting mechanism being configured as a wobble transmission. The drive pinion (2) comprises a first front-end gearing (9) and a disk (10) comprises a second front-end gearing (11), which first and second front-end gearings mesh partially with each other, and the number of teeth of said front-end gearings differ from each other by at least one tooth. To reduce the overall dimensions of the device and avoid gearing lash, it is proposed, on the one hand, to connect the disk (10) rotationally fast to the camshaft (1) and on the other hand, to configure the disk (10) in axial direction of the camshaft (1) as a flexible element that can be deformed in axial direction by an adjusting device (thrust plate 17).

Abstract: According to a control strategy, a cylinder valve control device is monitored and operation of the engine is modified. The cylinder valve control device includes a driving shaft driven by the engine to drive an intermediate member which in turn drives a cam arranged to open an engine intake valve, and a driver which is operative in response to a command to vary an amount of eccentricity of the intermediate member with respect to a shaft axis of the driving shaft. During one mode of engine operation, the intermediate member is supported in a support for rotation about an axis in eccentric condition with respect to the shaft axis to accelerate and decelerate the cam with respect to rotation of the driving shaft. During another mode of engine operation, the intermediate member is in concentric condition with respect to the shaft axis to provide a synchronous motion of the cam with rotation of the driving shaft. In response to the eccentricity of the intermediate member, the engine operation is modified.

A drive member is rotatable with a driving shaft, and a cam for co-axial rotation relative to the driving shaft. An intermediate member is mounted in a support for rotation so as to rotate eccentrically with respect to an axis of the driving shaft. The support is held for movement within a plane perpendicular to the shaft axis. A control rod is drivingly associated with the support and driven by an actuator.
