    Abstract: In a hydraulic valve comprising a spool, one or more band-shape check valves and an enclosing bolt or snout, the check valve may be compressed to the point of excessive wear or failure and may impede spool movement. The problem outlined is solved by an inventive hydraulic valve for use with a cam phasing apparatus of an internal combustion engine. The hydraulic valve comprises a hollow bolt or snout, check valves, and a spool disposed inside the bolt while still being able to shift axially within the bolt. The bolt and spool are configured to provide fluid passageways between the spool and the cam phasing apparatus depending on a translational displacement of the spool. Furthermore, the spool is configured to allow an oil flow through the fluid passageway, yet limit a compression of the band-type check valves.

    Abstract: A valve mechanism for an internal combustion engine is provided with a cam that rotates in conjunction with rotation of a crankshaft, an engine valve that is lifted and opened along with rotation of the cam, a variable lift amount mechanism that is arranged between the cam and the engine valve and varies the maximum amount of lift of the engine valve, and a lost motion mechanism that is arranged between the cam and the engine valve and absorbs the amount of lift of the engine valve by contracting when drive force is received from the cam to maintain a closed state of the engine valve. The maximum amount of contraction of the lost motion mechanism is set to such a value that the lost motion mechanism absorbs the minimum value of the maximum lift amount of the engine valve.

    Abstract: An internal combustion engine includes a camshaft with a lobe rotatable about a camshaft axis and a follower and which follows the lobe and is reciprocated along a follower axis by the lobe. A contact force is generated between the lobe and the follower such that the contact force is cyclic between a minimum contact force and a maximum contact force. The follower axis is offset from the camshaft axis such that the lobe contacts the follower at a contact point that is substantially aligned with the follower axis when the maximum contact force is generated between the lobe and the follower. In this way, the side load on the follower is minimized.

    Abstract translation: 内燃机包括凸轮轴，凸轮轴具有可绕凸轮轴轴线和从动件旋转的凸角，并且跟随凸角并且沿着从动轴线由凸角往复运动。 在凸角和从动件之间产生接触力，使得接触力在最小接触力和最大接触力之间是循环的。 从动轴偏离凸轮轴轴线，使得当在凸角和从动件之间产生最大接触力时，凸角接触从动件，该接触点基本上与从动轴对齐。 以这种方式，从动件的侧向载荷最小化。
