Abstract: PURPOSE:To prevent working fluid from flowing out from a reservoir chamber when an engine is brought to a stop, by a method wherein, in a hydraulic lifter mounted on the dynamic valve system of an engine, a check valve is mounted to one of two body parts which are located so as to form a reservoir chamber. CONSTITUTION:In a hydraulic lifter in which working fluid from an oil pump is supplied to a pressure chamber 37 through a passage 27, a pipe 29, a reservoir 30, and a passage 32, and a cam shaft 21 is rotated in linkage with rotation of an engine. When first and second bodies 22 and 23 are pushed downward, an oil pressure in the pressure chamber 37 is increased, and a check valve 42 is closed. In which case, forced oil in the pressure chamber 37 flows out to an oil pan through a gap 34. Thereafter, by further rotating the cam shaft 21, the bodies 22 and 23 are lifted through the force of a spring 38, and the overall length of a lift is expanded by a given distance. As a result, an oil pressure in the pressure chamber 37 is decreased to open the check valve 42, the oil in the reservoir 30 flows in the pressure chamber 37 to restore the length of a hydraulic lifter 10 to its original size on the whole.
Abstract translation: 目的：为了防止工作液体在发动机停止时从储存室流出，通过一种方法，其中在安装在发动机的动态气门系统上的液压升降器中，止回阀安装在两个 身体部位被定位成形成储存室。 构成：在液压提升器中，油泵的工作流体通过通道27被供应到压力室37，管29，储存器30和通道32以及凸轮轴21与旋转相联动地旋转 的发动机。 当第一和第二主体22和23被向下推压时，压力室37中的油压增加，止回阀42关闭。 在这种情况下，压力室37中的强制油通过间隙34流出到油盘。此后，通过进一步旋转凸轮轴21，主体22和23通过弹簧38的力被提升，并且总体上 电梯的长度扩大一定距离。 结果，压力室37中的油压降低以打开止回阀42，储存器30中的油在压力室37中流动，从而将液压升降器10的长度整体恢复到其原始尺寸。

Abstract: A lash adjuster includes a body (11), a plunger (12) which is inserted into the body (11) and a partitioning member (13) inserted into the plunger (12). The partitioning member has an oil passage end (33) located above the oil passage hole (26). The partitioning member (13) has an oil-passage defining portion (32) located opposite the recessed groove (31) and defining an oil passage (40) between itself and a groove face of the recessed groove (31). The partitioning member (13) defines a low-pressure chamber (23) inside. The low-pressure chamber (23) reserves a hydraulic fluid flowing through the oil passage hole (26), the oil passage (40) and the oil passage end (33). The low-pressure chamber (23) causes the reserved hydraulic fluid to flow through the valve hole (20) into the high-pressure chamber (22).
