    • The present invention provides an internal combustion engine component, such as a cylinder head or tappet block, which is adaptable to a variety of pushrod positions and angles. A large pushrod aperture is formed in the engine component. The aperture is large enough to accommodate one or more pushrods passing therethrough at a variety of different angles and positions. A composite pushrod hole adapter plate is attached to the engine component over the aperture. The adapter plate has one or more pushrod holes machined therethrough at desired angles and positions. A counter bore is preferably formed around each pushrod hole to provide a seat for the end of a pushrod housing. A plurality of different adapter plates, having pushrod holes and counter bores formed therein at different angles and positions, may alternatively be attached to the engine component, thereby adapting the engine component for use in combination with various different engine designs. The component may be provided along with one or more adapter plates as a kit which may be assembled onto an internal combustion engine such that a pushrod passes coaxially through each pushrod hole in the adapter plate and an end of a pushrod housing is positioned in the counter bore around the pushrod hole to form a seal between the adapter plate and the pushrod housing.
    • 本发明提供一种适用于各种推杆位置和角度的内燃机部件,例如气缸盖或挺杆块。 在发动机部件中形成有大的推杆孔。 孔径足够大以容纳以各种不同角度和位置穿过的一个或多个推杆。 复合推杆孔适配器板通过孔径连接到发动机部件。 适配器板具有在期望的角度和位置上通过其加工的一个或多个推杆孔。 优选地,在每个推杆孔周围形成一个反向孔,以提供用于推动壳体的端部的座。 可替换地,在不同角度和位置处形成有推杆孔和对应孔的多个不同的适配器板可以附接到发动机部件,从而使发动机部件与各种不同的发动机设计结合使用。 组件可以与一个或多个适配器板一起提供,作为可以组装到内燃机上的套件,使得推杆同轴地穿过适配器板中的每个推杆孔,并且推杆壳体的端部位于计数器中 围绕推杆孔,以在适配器板和推杆壳体之间形成密封。
