摘要： Piston assemblies for use in fluid translating devices normally are made of hardened metal alloy materials which require very smooth surface and are always subject to varying degrees of thermal expansion when being operated at high operating temperatures. In the subject arrangement, a piston assembly is provided and is constructed of most, if not all, ceramic components. The piston assembly includes a ceramic piston having a spherical head portion at one end thereof which rests in a spherical cavity of a ceramic slipper and held therein by a cylindrical ring. The cylindrical ring can be of a one-piece or a two-piece design which is in contact with the spherical head portion and bonded to the ceramic slipper, thus, retaining the spherical head portion. The cylindrical ring could also be made of a metallic material. The metallic ring is bonded to the ceramic slipper and subsequently swaged to hold the spherical head portion within the spherical cavity. The subject ceramic piston assembly provides a very smooth surface which reduces sliding friction and likewise the effects of thermal expansion and inertia are minimized by the use of a ceramic material. Consequently, the subject piston assembly is very efficient when operating at high temperatures and, likewise, is easy to manufacture and assemble.
摘要翻译： 用于流体转换装置的活塞组件通常由需要非常光滑表面的硬化金属合金材料制成，并且在高操作温度下操作时总是经受不同程度的热膨胀。 在主题布置中，提供活塞组件并且由大多数（如果不是全部）陶瓷部件构成。 活塞组件包括陶瓷活塞，其陶瓷活塞的一端具有球形头部，该球形头部位于陶瓷拖鞋的球形腔中，并由圆柱形环保持在其中。 圆柱形环可以是与球形头部接触并结合到陶瓷拖鞋上的一体式或两件式设计，因此保持球形头部。 圆柱形环也可以由金属材料制成。 金属环结合到陶瓷拖鞋上，随后模锻以将球形头部保持在球形腔内。 主体陶瓷活塞组件提供了非常光滑的表面，其减少了滑动摩擦，并且同样通过使用陶瓷材料来最小化热膨胀和惯性的影响。 因此，当在高温下操作时，主体活塞组件非常有效，并且同样易于制造和组装。

摘要： A process of providing an inorganic anti-stick coating directly on non-oriented, semi-processed electrical steels by applying to such steels a coating solution containing Al.sup.+++, Mg.sup.++, and H.sub.2 PO.sub.4.sup.- in a specified relative relationship, the concentration of Al.sup.+++, Mg.sup.++, and H.sub.2 PO.sub.4.sup.- comprising 100 parts by weight calculated as Al.sub.2 O.sub.3, MgO and H.sub.3 PO.sub.4, respectively, on a water-free basis. The coating solution may additionally contain from 0 to 150 parts by weight of colloidal silica on a water-free basis. Chromic anhydride (C.sub.r O.sub.3) may be added to the coating solution to improve its wettability and improve the moisture resistance of the anti-stick coating. The coating solution is so diluted with water as to provide a uniform coating as thin as possible to prevent lamination sticking and having a coating weight of less than 2 grams per square meter on each side. The coated electrical steel is subjected to a heat treatment to cure the anti-stick coating thereon.

摘要： In order to achieve great engine efficiency, heat, normally dissipated through the cooling system, is directed through the exhaust passage to increase the turbocharger speed. Ceramic valve guides capable of withstanding high temperature ranges are being used for increased engine efficiency. Unfortunately, the resultant interference fit achieved through conventional shrink fitting the ceramic valve guide into the cylinder head will be lost once the engine is at operating temperatures due to the differential thermal expansion between the ceramic and the cylinder head material. The present invention provides a simple means for ensuring that the ceramic valve guide will be mounted within a cylinder head in a way that ensures that the ceramic valve guide is held in place within the cylinder head throughout the operating cycles of the engine. This is accomplished by utilizing a securing assembly which circumferentially surrounds the ceramic valve guide. The securing assembly includes a lower and an upper securing element and a spring disposed between the lower and the upper securing element. When installed in the engine, a valve spring places an axial load on the securing element which compresses the spring and forces the lower and the upper securing element into radial engagement with the ceramic sleeve and the cylinder head. Thereby, forcibly connecting the ceramic valve guide and the cylinder head.
摘要翻译： 为了获得很好的发动机效率，通常通过冷却系统耗散的热被引导通过排气通道以增加涡轮增压器的速度。 能够承受高温范围的陶瓷阀导向器用于提高发动机效率。 不幸的是，由于陶瓷和气缸盖材料之间的热膨胀差异，发动机处于工作温度时，通过常规的收缩将陶瓷阀导向件装入气缸盖中而产生的干涉配合将会消失。 本发明提供了一种简单的方法，用于确保陶瓷阀引导件将被安装在气缸盖中，以确保在发动机的整个操作循环期间陶瓷阀引导件保持在气缸盖内的适当位置。 这通过利用围绕陶瓷阀引导件的固定组件实现。 固定组件包括下固定元件和上固定元件以及设置在下固定元件和上固定元件之间的弹簧。 当安装在发动机中时，阀弹簧将轴向载荷放置在固定元件上，该固定元件压缩弹簧并迫使下固定元件和上固定元件与陶瓷套筒和气缸盖径向接合。 从而，强制地连接陶瓷阀引导件和气缸盖。

摘要： In order to achieve great engine efficiency, heat, normally dissipated through the cooling system, is directed through the exhaust passage to increase the turbocharger output. Conventional iron base valve guides cannot operate effectively within the high temperature ranges. Therefore, ceramic valve guides capable of withstanding high temperature ranges are being used for increased engine durability. Unfortunately, ceramic valve guides are difficult to install into a cylinder head using any currently available techniques. The present invention provides a simple means for mounting a ceramic valve guide assembly (52) within a cylinder head (18). A ceramic sleeve (70) is inserted into a metallic sleeve (80). The ceramic sleeve (70) and the metallic sleeve (80) are machined so that an interference fit is obtained when assembled to define the valve guide assembly (52). The valve guide assembly (52) is installed into the cylinder head (18) in a normal manner. Proper selection of the dimensions and materials for the ceramic sleeve (70) and the metallic sleeve (80) will result in a design wherein the stresses and contact pressures of the ceramic sleeve (70), the metallic sleeve (80), and the cylinder head (18) are each kept reasonable at all conditions encountered during manufacturing, assembly, and operation of the engine.
