摘要： A valve keeper installation device for facilitating installation of valve keepers. The valve keeper installation device includes a pliers member for engaging and compressing valve locks including: a jaw portion for providing a compressive force; a handle portion designed for being grasp by a human hand, and having two opposed members such that squeezing both opposed members towards each other tightens the jaw portion providing a compressive force; and a cup portion integrally coupled to the jaw portion, and designed for engaging a valve keeper, the cup portion includes a first curved member integrally coupled to a first jaw member and a second curved member integrally coupled to a second jaw member, the first and second curved members being positioned such that an longitudinal axis of the cup portion is substantially collinear with a longitudinal axis of the device.

摘要： The method of facilitating assembly and disassembly of valves in a cylinder head uses a gripping tool which has a base consisting of a flat ring onto which are mounted three posts extending upwardly therefrom. Rotatable and slidable clips with magnets are mounted on at least two of the posts to capture the loose key bolts. A plate is attached to the top of the posts and a clip may extend upwardly therefrom to permit attachment of an adapter for use with a drill press. The flat ring is centered over the top of the valve stem and key bolt and rests on top of the upper cup which presses against the top of the ring which retains the spring. Force applied to the top of the tool presses down on the upper cup, compressing the spring to release the key bolt. For re-assembly, a centering ring holds the spring centered with the cam bucket bore, providing the contact surface for the flat ring. To facilitate transfer of the cylinder head between work stations, an elastic sheet with an opening for each valve stem locks the valves in place before assembly has been completed.
摘要翻译：促进气缸盖中的阀的组装和拆卸的方法使用具有由平环组成的基座的夹紧工具，其上安装有从其向上延伸的三个柱。至少有两个支柱安装有带磁铁的可旋转和可滑动的夹子，以捕获松动的钥匙螺栓。板被附接到柱的顶部，并且夹子可以从其向上延伸以允许将适配器附接到用于钻床的适配器。平面环位于阀杆和键螺栓的顶部上方，并且位于上杯的顶部，该顶部压靠保持弹簧的环的顶部。施加到工具顶部的力压在上杯上，压缩弹簧释放钥匙螺栓。对于重新组装，定心环将弹簧以凸轮斗孔为中心，为平环提供接触面。为了便于工作站之间的气缸盖的传送，在组装完成之前，具有用于每个阀杆的开口的弹性片将阀锁定在适当位置。

摘要： This invention relates to a set of tools for removing lugless snap rings from the internal annular grooves provided therefor in parts containing internal bores, these tools consisting of a pointed tool for making an indentation in the base of the groove between the ends of the ring, a plunger-actuated ball magazine for placing a ball in the indentation thus formed preparatory to driving the ring aroung in its groove until one of its ends rides up upon the ball to create a gap therebeneath, a clamping tool for holding the ring in its groove against further relative rotation, a wedge for movement into the gap underneath the raised end of the ring, and a wedge-driving subassembly for moving the wedge into the gap to a point where the raised end of the ring is free of the groove and in position to be grasped and removed. The invention also encompasses the novel method for removing lugless snap rings that includes the steps of making an indentation in the base of the groove between the ends of the ring, inserting a ball in the indentation, rotating the ring within its groove until one of its ends rides up upon the ball creating a gap therebeneath, holding the ring in the groove against further relative rotation, driving a wedge into the gap underneath the ring until the raised end thereof is free of the groove, and pulling upon the end thus freed to remove the ring.
摘要翻译：本发明涉及一组用于从包含内孔的部件中提供的内部环形槽中移除无钩状卡环的工具，这些工具由用于在环的端部之间的凹槽的基部中形成凹陷的尖锐工具组成，用于将球放置在如此形成的凹陷中的柱塞致动的球形仓，准备将环在其槽中驱动，直到其一端靠在球上以形成其间的间隙，夹紧工具用于将环保持在其凹槽中防止进一步的相对旋转，用于移动到环的升高端部下方的间隙中的楔子以及用于将楔形物移动到间隙中的楔形驱动子组件，其中环的上升端部没有槽，并且被抓住的位置。本发明还包括用于去除无钩扣卡环的新颖方法，该方法包括以下步骤：在环的端部之间的凹槽的底部形成凹陷，将球插入压痕中，将环旋转到凹槽内，直到其中的一个端部靠在球上形成一个间隙，将环保持在凹槽中，防止进一步的相对旋转，将楔形件推入环之下的间隙中，直到其上升的端部没有凹槽，取出戒指

摘要： A check valve comprises a housing defining a valve seat thereon and a valve member reciprocally mounted in the housing to normally engage the seat for blocking fluid flow therepast. Two pairs of split retaining members are mounted in axially spaced relationship on a stem of the valve member and are expanded axially thereon by a compression coil spring for biasing the valve member to its closed position. A stop member is secured on an end of the stem of the valve member to prevent movement of one pair of the retaining members therepast. A slot is formed axially through the stop member and extends partially in the stem of the valve member to expose an end of the spring.
