    Abstract: A drive shaft is synchronously driven by an internal combustion engine. A cylindrical hollow cam shaft is rotatably disposed about the drive shaft. The cam shaft has thereon a cam which actuates a valve of the engine. A first flange is formed on one end of the cam shaft. A second flange is connected to the drive shaft to rotate therewith. The second flange faces the first flange. First and second radially extending grooves are formed in mutually facing surfaces of the first and second flanges respectively. The first and second grooves are arranged at opposite sides with respect to an axis of the drive shaft. An annular disc is disposed between the first and second flanges. The annular disc has first and second pins which are slidably engaged with the first and second grooves respectively. A control housing rotatably receives therein the annular disc. The control housing is pivotal in a direction perpendicular to an axis of the drive shaft and has therein a cam receiving circular opening. A control shaft has thereon a circular eccentric cam which is slidably received in the cam receiving circular opening of the control housing. A pair of annular flanges are provided on the control shaft to intimately put therebetween a thicker portion of the control housing thereby to suppress an undesired axial displacement of the control housing on and along the control shaft.

    Abstract: A cylinder valve control stem for a vehicle drivetrain including a transmission and an engine having a variable valve control mechanism which can vary valve lift diagram in response to a control signal. A controller develops the control signal in response to varying operating condition of the engine. The controller derives, upon initiation of a shift in the transmission, engine speed to be established after completion of the shift and corrects the control signal such that the variable valve control mechanism provides one of various valve lift diagrams whose predetermined value in engine speed is not exceeded by the derived engine speed.

    Abstract: A control member holder on cam brackets keeps a control member rotatable on the cam brackets, while a control cam holder on supports keeps control cams fixed to the control member cooperating with the supports in such a manner as to cause the supports to move in a plane perpendicular to a shaft axis of a driving shaft to vary eccentricity of intermediate members rotatably supported by the suppports as the control member rotates.

    Abstract: A control system for a four-cycle internal combustion engine controls a cam drive mechanism for an intake valve such that a cam of the cam drive mechanism maintains a valve open duration of the intake valve at a short valve open duration in response to a shift from engine operation at low speed with low load to engine operation at low speed with high load, and the cam increases the valve open duration of the intake valve in response to a shift from engine operation at low speed with low load to engine operation at low speed with middle load that is higher than the low load but lower than the high load.

    Abstract: A mechanism for transmitting rotational motion from an input shaft to an output shaft includes a link which is constrained to move about an orbital path, the input shaft being coupled to the link so that rotation thereof will drive the link about its orbital path, and the output shaft being coupled to the link so that orbital motion of the link will cause the output shaft to rotate. One of the shafts is coupled to the link by means of a pair of interengaging components, one component being provided on the shaft for rotation therewith and the other component being pivotally mounted on the link, the pivotal axis of the component moving in a circular path upon rotation of the link, the axis of said circular path coinciding with the axis of rotation of the link, a lever being pivotally connected at one end to the component mounted on the link and at the other end to a pivot isolated from movement of the link, so that upon movement of the link about its orbital path an oscillatory rotation will be imposed on the component mounted on the link thus providing a sinusoidal variation in rotation of the shaft relative to the link.

    Abstract: A driving connection between a first and hollow shaft (1) and a second shaft (3) within it, the axes (19, 20) of the two shafts being parallel at all times. By relative radial displacement of the two axes, the first shaft rotates at a variable and fluctuating speed within each revolution in response to uniform rotation of the second shaft. The ball (36) or part-cylindrical (22) end of a radial arm (2), carried by the second shaft, engages rotatably with a recess (37, 31) in a block (4) movable in a radial slideway (23) formed on the first shaft. Axial compactness is promoted by the arm, block and slideway all lying in a common radial plane (30), and radial compactness by the manner of engagement between the arm end (36, 22) and the corresponding recess (37, 31). The invention finds particular use where the first shaft (1) is the camshaft of an internal combustion engine, and in which the relative movement of the shaft axes (19, 20) may therefore be used to vary the timing of the engine valves (7, 8).
