Abstract: A lash adjuster includes a plunger having a bottom wall with a valve hole and a peripheral wall having an oil passage hole and an inner periphery formed with a recessed groove, the plunger defining a high-pressure chamber between the bottom wall and a body, and a partitioning member having an oil passage end located above the oil passage hole. The partitioning member has an oil-passage defining portion located opposite the recessed groove and defining an oil passage between itself and a groove face of the recessed groove. The partitioning member defines a low-pressure chamber reserving a hydraulic fluid flowing through the oil passage hole, the oil passage and the oil passage end. The low-pressure chamber causes the reserved hydraulic fluid to flow through the valve hole into the high-pressure chamber. The partitioning member is formed into a cylindrical shape and extends in an up-down direction without any stepped part.
Abstract translation: 间隙调节器包括具有阀孔的底壁和具有油通孔的周壁和形成有凹槽的内周的柱塞，柱塞在底壁和主体之间限定高压室，以及 具有位于所述油通孔上方的油路端的分隔构件。 分隔构件具有与凹槽相对设置的油通道限定部分，并且在其自身和凹槽的凹槽面之间限定油通道。 分隔构件限定了储存流过油通道孔，油路和油路端的液压流体的低压室。 低压室使保留的液压流体通过阀孔流入高压室。 分隔构件形成为圆柱形，并且在上下方向上延伸而没有任何台阶部分。

Abstract: A roller lifter for internal combustion engines is provided, which has higher rigidity of the lifter body, prevents cocking in the cylinder, and can achieve a size reduction. The roller lifter includes a cylindrical lifter body having a sliding surface on an outer circumferential surface thereof and a roller rotatably attached to the lifter body via an axial support pin and making contact with a rotating cam lobe. The lifter body includes a pair of support portions supporting the axial support pin. The axial support pin is mechanically fastened to the pair of support portions, with both ends thereof inserted in support holes formed in the support portions. The lifter body includes an anti-rotation retainer extending radially outward from the sliding surface. The sliding surface is formed on both front and rear sides in the sliding direction of the anti-rotation retainer.
Abstract translation: 本发明提供一种内燃机用滚子式升降机，其具有较高的升降机体的刚性，能够防止气缸中的起动，能够实现小型化。 滚子式升降机包括在其外圆周表面上具有滑动表面的圆柱形升降机主体和经由轴向支撑销可旋转地附接到升降机主体并与旋转凸轮凸角接触的滚子。 升降机主体包括支撑轴向支撑销的一对支撑部分。 轴向支撑销机械地紧固到一对支撑部分，其两端插入形成在支撑部分中的支撑孔中。 升降机体包括从滑动表面径向向外延伸的防旋转保持器。 滑动面形成在防旋转保持器的滑动方向的前后两侧。

Abstract: A rocker arm includes a pair of sidewalls disposed along a heightwise direction so as to be opposed to each other. The sidewalls define a space to house a roller and have opposed portions extending in the heightwise direction relative to adjacent portions which are adjacent to the opposed portions. The opposed portions have thinner portions having smaller thicknesses than the adjacent portions.
