    摘要： A fuel injector is provided which includes a director, such as a ball, mounted downstream of the fuel injection port. When the valve is actuated, fuel exits the injection port. Fuel adheres to the ball until it reaches the equator of the ball. At the equator, the fuel begins to separate from the ball and forms a sheeted, cone-shaped configuration. When used with poppet valve injectors, the present invention preferably includes a wall manifold above the ball. Air from an air source, such as from the engine vacuum is introduced through the wall. Air travels through an air distribution chamber at a ninety degree angle to the direction of fuel flow. The air stream is directed to the ball's equator. This blast of air causes the fuel to atomize to a droplet size in the range of 3 to 6 microns SMD. When the invention is used with solenoid actuated fuel injectors, a ball is mounted downstream of the director plate. In this case, an air housing carries air from an air source to an air blast chamber. The air blast chamber directs air at a ninety degree angle to the sheeted fuel. The air is directed to the equator of the ball. Instead of using a ball, directors of other shapes could be used such as ground balls of various shapes and truncated cones.

    摘要翻译： 提供一种燃料喷射器，其包括安装在燃料喷射口下游的导向器，例如球。 当阀门启动时，燃油从喷射口排出。 燃料附着在球上直到球到达赤道。 在赤道处，燃料开始与球分离并形成一个圆形的锥形构型。 当与提升阀注射器一起使用时，本发明优选地包括在球上方的壁歧管。 来自空气源的空气，例如来自发动机真空的空气通过壁被引入。 空气通过空气分配室与燃料流动方向成90度角。 气流被引导到球的赤道。 这种空气爆炸导致燃料雾化至3至6微米SMD范围内的液滴尺寸。 当本发明与电磁致动燃料喷射器一起使用时，在导向板的下游安装一个球。 在这种情况下，空气壳体将空气从空气源运送到鼓风室。 空气鼓风室将空气以90度角度引导到片状燃料。 空气被引导到球的赤道。 不使用球，可以使用其他形状的导演，例如各种形状的球磨和截锥体。

    摘要： A valve actuating mechanism includes opening and closing rotary cams rotatable together about a primary axis and a rocker pivotable about a first pivot axis spaced from the primary axis. The rocker includes first and second rocker arms connected to actuate a valve by oscillating motion about the pivot axis. The first and second rocker arms respectively carry opening and closing cam followers operable by the opening and closing cams for positively oscillating the rocker in either direction. The closing cam follower has a pad engagable with the closing cam and carried by a hydraulic lash control piston slidable in a cylinder of the second rocker arm. The cylinder is connected with a pressure oil supply having a check valve preventing reverse oil flow. A bleed orifice in the pad is sized to allow restricted oil flow from the cylinder to avoid excessive loading of the mechanism. The orifice may be blocked by the cam to limit oil flow during operation of the pad on the cam base circle. The piston is advanced by the oil pressure during cam base circle operation to take up lash between the cams and cam followers.
