    Abstract: A valve system for an internal combustion engine includes a valve member having a head and a stem extending from the head, the head being capable of forming a seal with a valve seat of the internal combustion engine and the stem having at least one cylinder in an end portion thereof, and a component for contacting a portion of a rocker arm of the engine, the component being movable in the cylinder between a first position and a second position closer to the rocker arm than the first position. Structure is provided for moving the component between the first position and the second position to change lift of the valve member. The system adjusts valve lift according to speed of the engine to improve combustion efficiency.

    Abstract: A valve stem which is located for axial movement; a valve lever is pivotally mounted at one end and is attached adjacent the other end to the end of the valve stem, the valve lever defines a track; a drive pin engages in the track the drive pin being mounted at one end of a first link the other end of the link being pivotally mounted about a fixed pivot, a second link is pivotally mounted at one end about moveable pivot, the first and second links being interconnected by an intermediate link pivotally attached to said first and second links at positions separated from their pivots, a drive link is pivotally connected at one end to the pivotal connection between the second link and intermediate link and at the other end to a crank, so that rotation of the crank will cause the linkage to oscillate and the drive pin to perform a reciprocating motion along an arcuate path; the trank has a first portion which is engaged by the drive pin when the valve is closed and coincides with the arcuate path of the drive pin and a second portion which diverges from the path of the drive pin, so that engagement of the second portion by the drive pin will cause the valve lever to move opening and closing the valve; and means being provided for movement of the pivot to vary the timing and duration of opening of the valve.

    Abstract: A valve mechanism includes a poppet type valve, a valve lever pivotally mounted at one end and attached at the other end to the end of the stem of the valve, the valve lever defines a track in which is located a drive pin and a drive mechanism is arranged to drive the drive pin in oscillatory manner; the track has a first portion which, when the valve is closed is engaged by the drive pin and coincides with the path of the drive pin, and a second portion which diverges from the path of the drive pin so that when engaged by the drive pin movement of the drive pin will cause the valve lever to move, opening and closing the valve. Preferably the mean position of oscillation of the drive pin is adjustable so that the duration and amplitude of valve opening may be varied.

    Abstract: A single-row planetary bearing includes a single row of spherical rolling elements between an outer ring and an inner ring. A planetary gear is supported by a thrust bearing portion and is radially supported by the outer ring. The planetary gear performs a planetary motion while engaging with a driving rotor and a driven rotor at an eccentric side to adjust a rotational phase between the driving rotor and the driven rotor. The thrust bearing portion supports the planetary gear that is tilting with respect to the revolution centerline. The planetary gear has a recessed portion opened toward the thrust bearing portion. When the rotational phase is adjusted to a specific phase, the recessed portion is positioned at an anti-eccentric side opposite to the eccentric side with respect to a rotation centerline of the planetary gear.

    Abstract: Hydraulic spring drive apparatus comprising: a rotatable cam shaft having fixed thereon a number of cams; a number of rocker arms, one following each cam, each pivotally attached at one end to a pressure bar and at another to an expansible, compressible connecting means in turn connected to a crank portion of a crank shaft. The cams, crank shaft, and expansible compressible connecting means are arranged so that a number of connecting means expand against the compression of one connecting means. The pressure bar is movable to position the rocker arms for a selected degree of connecting means compression.
