    摘要: A fuel injection device having a pump piston which during the supply stroke pumps fuel from a pump work chamber into an injection line which leads to a fuel injection valve. Directly adjacent to the branching off of the injection line from the pump work chamber, at the diameter of the injection line, a valve seat is provided, at which the injection line then merges with a chamber into which a pressure valve closing member plunges. The valve closing member is tightly guided in a guide bore, loaded by a valve spring, and in the chamber has a pressure shoulder adjoining the sealing surface that cooperates with the valve seat. The rear side of the pressure valve closing member communicates with a continuously open relief line. Because of this construction, the pressure valve closing member operates as an equal-pressure valve and simultaneously as a deflecting piston as well, with the aid of which a pressure rise in the pump work chamber is built up in a retarded manner until such time as the pressure valve closing member comes to rest on a stop. A pressure rise of this type is particularly advantageous in connection with control of the injection phase by means of a magnetic valve subjected to the high pressure.

    摘要: A rotary printing machine including an impression cylinder which has at least two grippers for gripping the forward edge of a sheet of paper for drawing the paper onto the same at each appropriate instant in each cycle of operation of the machine, the grippers being movable circumferentially of the impression cylinder and retainable in a different position which is stationary relative to the impression cylinder, to vary the relative position of the sheet of paper on the cylinder while the cylinder is rotating.

    摘要: An coated particulate is provided with a graphite-impregnated resin coating. The oil field particulates may comprise any of gravel-pack sand, granular betonite, ground Gilsonite, calcium carbonate, glass beads, rock wool, shredded paper, metal spheres, ceramic beads, nut hulls, ground rubber, plastic beads, muscovite mica, calcined petroleum coke, and perlite. The resin may comprise as a binder one or more of a natural, synthetic, water-soluble, and organic resins. More specifically, the resins may comprise an organic film-forming resin such as an alkyd, polyurethane and epoxy. Alternatively, the resin may comprise a film-forming water-soluble polymer, such as a starch, carboxymethyl cellulose, hydroxyethyl cellulose, and xanthan gum. In a further alternative, the resin may comprise a resin-dispersed emulsion, such as a latex or acrylic.

    摘要翻译: 具有泵活塞的燃料喷射装置,其在供给冲程期间将来自泵工作室的燃料泵送到通向燃料喷射阀的喷射管线。 在喷射管直径处,直接与喷射管路分离出的离开泵入口管线的直径相同,设置有一个阀座,在该阀座处,注射管线与压力阀关闭件所在的腔室合并。 阀关闭构件被紧密地引导在由阀弹簧加载的引导孔中,并且在腔室中具有邻接与阀座配合的密封表面的压力肩部。 压力阀关闭构件的后侧与连续打开的浮雕线连通。 由于这种结构,压力阀关闭部件作为等压阀工作,同时作为偏转活塞,借助于此,泵工作室中的压力上升以延迟的方式被建立,直到 压力阀关闭件在停止时停止。 这种类型的压力上升与通过经受高压的电磁阀控制喷射相相关是特别有利的。
