摘要： Apparatus for adjusting the timing of a valve, particularly but not exclusively for use with a four-stroke internal combustion engine, is disclosed. The apparatus includes a cam (1), which engages a cam follower (4) which is arranged to actuate a valve mechanism (3) in response to rotation of the cam (1). The cam follower (4) is moveable in translation relative to the axis of rotation of the cam (1) to vary the extent of actuation of the valve in response to rotation of the cam (1). The cam follower (4) is shaped so that for a part of a cycle of rotation of the cam (1), the line of action of the force from the cam (1) to the follower (4) forces the follower (4) to move in translation. This movement is greater at low cam rotational speeds than at high cam rotational speeds and, due to the profile of the surfaces of the follower, the translational movement provides varying extents of valve actuation in dependence upon cam rotatonal speeds.
摘要翻译： 公开了一种用于调节阀的定时的装置，特别地但不排他地用于四冲程内燃机。 该装置包括凸轮（1），该凸轮接合凸轮从动件（4），凸轮从动件（4）被布置成响应于凸轮（1）的旋转来致动阀机构（3）。 凸轮从动件（4）能够相对于凸轮（1）的旋转轴线平移地移动，以响应于凸轮（1）的旋转而改变阀的致动程度。 凸轮从动件（4）的形状使得对于凸轮（1）的旋转周期的一部分，来自凸轮（1）到从动件（4）的力的作用线迫使从动件（4） 在翻译中移动。 这个运动在较低的凸轮转速下比在高凸轮转速下更大，并且由于从动件表面的轮廓，平移运动根据凸轮旋转速度提供不同程度的气门致动。

摘要： A body comprising a mixture of particulate materials is formed by mixing together aluminium and/or an aluminium alloy powder with a proportion of alumina powder, compacting and sintering the resultant mass, and reshaping the resultant mass under pressure after sintering. A body so formed possesses a high hot strength and, by the choice of appropriate proportions of the powdered materials is particularly suitable for forming the crown of an internal combustion engine piston. The invention also relates to the manufacture of such bodies and pistons.
