摘要： A two-step roller finger follower having a high-lift follower portion that pivots on a pivot shaft disposed on a low-lift follower portion, and having a lost-motion spring disposed between the high-lift follower and the low-lift follower to bias the high-lift follower toward the high lift cam lobe. Various bearing cups and roller shaft sleeve embodiments are shown, all of which allow for improved shaft and needle bearing arrangements. A z-stop formed by the bearing cups and/or the shaft sleeve limits the range of travel of the high-lift follower with respect to the low-lift follower. Various z-stop embodiments are provided including a non-contacting roller shaft sleeve that grounds the high-lift follower to the low-lift follower independent of the roller shaft.

摘要： An improved pin housing sub-assembly configured for reliable assembly and stability as an intermediate sub-assembly. The length of the plunger return spring is greater than the diameter of the spring well in the pin housing, such that the spring cannot be accidentally installed sideways in the well. During assembly, the non-compressed longer spring places the pushrod seat flush with the end of the pin housing. A shallow annular groove is provided in the inner wall of the pin housing near the outer end thereof, and an expansion ring may be installed therein when the plunger return spring is slightly compressed. The expansion ring holds the sub-assembly together as an intermediate but is displaced by the spring tower in a subsequent assembly step to become the locking ring between the pin housing and the spring tower, as in the prior art.

摘要： A valve deactivation lifter including means for restricting relative rotation between the pin housing and the lifter body. When used in a V-style or slant engine, a prior art deactivation lifter can be subject to oil drainage during engine shutdown if the oil supply port in the pin housing rests in the “down” position. In an improved lifter, relative rotation between the pin housing and the lifter body is limited and the pin housing is oriented such that the oil supply port is never on the underside of the pin housing. Rotation may be limited by any of several means, for example, a ball disposed in a dimple in the pin housing and extending into a longitudinal groove in the lifter body, and a flat on the pin housing and locking means installed in the lifter body to engage the flat and thus prevent rotation of the pin housing.
摘要翻译：一种阀门失活升降机，包括用于限制销壳体和升降机体之间的相对旋转的装置。当用于V型或倾斜发动机时，如果销壳中的供油口处于“向下”位置，则现有技术的停用升降机可以在发动机关闭期间进行排油。在改进的升降机中，销壳体和升降机体之间的相对转动受到限制，并且销壳体定向成使得供油口不会在销壳体的下侧。旋转可以通过几种手段中的任何一种来限制，例如，设置在销壳体中的凹坑中并延伸到升降机主体中的纵向凹槽中的球，以及安装在升降机主体中的销壳体和锁定装置上的平面接合平板，从而防止销壳体旋转。

摘要： An improved SHVL for an internal combustion engine comprises an improved arrangement for locking a spring tower into a pin housing. The spring tower is provided with an annular OD groove as in the prior art. The pin housing ID groove is modified to have a two-step groove comprising two adjacent regions having different depths (different diameters) and having a distinct transition lip therebetween. A spring clip of the correct size seats properly in the spring tower groove and in the lesser-diameter pin housing groove, resulting in a correct overall length of the SHVL. Any oversize clip is caught between the lower lip of the spring tower groove and the transition lip of the two-step pin housing groove, resulting in a SHVL distinctly shorter than nominal, which is easily detected by either direct length measurement or a gauge.
摘要翻译：用于内燃机的改进的SHVL包括用于将弹簧塔锁定到销壳体中的改进布置。弹簧塔设有如现有技术中的环形OD槽。销壳体ID槽被修改为具有包括具有不同深度（不同直径）的两个相邻区域并且在它们之间具有不同的过渡唇的两级槽。正确尺寸的弹簧夹适当地安装在弹簧塔槽和较小直径的销轴承槽中，从而形成SHVL的正确总长度。任何尺寸过大的夹子夹在弹簧塔槽的下唇与两步式销外壳槽的过渡唇缘之间，导致明显短于标称的SHVL，这可以通过直接测量或量规轻松检测。

摘要： A bearing design for a roller finger follower assembly includes an outer arm having a pair of openings, a shaft extending across the outer arm through the openings, a pair of lateral follower rollers mounted at opposite ends of the shaft; and a pair of bearings rotatably supporting the lateral follower rollers. The shaft is not a member of the bearing. Therefore, a force acting on the rollers travels through the rollers directly into the bearing and into the outer arm which reduces the potential for the rollers to become detached from the shaft. An inboard bearing design involves an inner bearing race integrated into the rollers. An outboard bearing design involves an inner bearing race integrated in the outer arm and an outer bearing race integrated into the rollers.

摘要： An alignment feature for preventing in-bore rotation of an engine tappet. A first portion extends outwards from a tappet and a second portion extends into a hole in the tappet. The first portion extends longitudinally past the mounting hole such that when the feature and tappet are installed in an engine bore, the entire feature is prevented from rotation within the hole. The second portion extending orthogonally from the first portion into the mounting hole need not be close-fitting to the hole. The first portion may be substantially semi-cylindrical, having a convex cylindrical outer surface for fitting the walls of a semi-cylindrical channel in the engine bore and a concave cylindrical inner surface for fitting the outer wall of the tappet. The pin portion is preferably cylindrical. Other pin shapes are possible. The alignment feature may or may not be hardened.

摘要： A fuel pump actuator comprising a body portion and a contact end fitted to the body portion for actuating a mechanical fuel pump in response to a camshaft lobe. A roller mounted to the body portion is configured to ride on the lobe. The contact end of the actuator engages a plunger of the fuel pump. The body portion of the actuator is preferably a body portion of a conventional hydraulic valve lifter and preferably includes a lash adjuster and is reciprocally disposed in a bore on the engine block. Lubrication of the reciprocating actuator is also similar to the lubrication provided to conventional valve lifters and lash adjusters. The contact end of the actuator is configured to reduce the mass of the actuator. Several styles of the contact end and ways of attaching the contact end to the body portion are provided.
