摘要： PROBLEM TO BE SOLVED: To provide a lash adjuster capable of reducing an amount of oil leaked to outside, and easily controlling a leakage-down time.SOLUTION: In a lash adjuster 10, a peripheral groove 21f is formed on an entire periphery of an outer peripheral wall 28 of a plunger 21 nearer a high pressure chamber 11b than an induction hole 21e, and a return hole 21g communicated with a reservoir chamber 21c is formed. Thereby, pressurized oil flowing in a clearance formed between an outer peripheral wall 28 of the plunger 21 and an inner peripheral wall 13 of a body 11 from the high pressure chamber 11b reaches the peripheral groove 21f before reaching the introduction hole 21e, and flows in the reservoir chamber 21c via the return hole 21g. Therefore, the pressurized oil flowing in a separator chamber 21b via the introduction hole 21e is reduced. Also, length of the clearance through which the pressurized oil passes gets shorter, and the pressurized oil is returned to the reservoir chamber 21c from the high pressure chamber 11b in a short time. Therefore, a leakage-down time can be easily controlled by adjusting a size of the clearance.
摘要翻译：要解决的问题：提供一种能够减少泄漏到外部的油量的间隙调节器，并且容易控制泄漏停机时间。解决方案：在间隙调节器10中，周向槽21f形成在形成了比吸入孔21e更靠近高压室11b的柱塞21的外周壁28和与储存室21c连通的返回孔21g。由此，从形成在柱塞21的外周壁28与主体11的内周壁13之间的高压室11b流动的加压油在到达导入孔21e之前到达周缘槽21f，并流入储存室21c经由返回孔21g。因此，经由导入孔21e在分离器室21b中流动的加压油减少。此外，加压油通过的间隙的长度变短，并且加压油在短时间内从高压室11b返回到储存室21c。因此，可以通过调节间隙的大小容易地控制泄漏停机时间。

摘要： PROBLEM TO BE SOLVED: To provide a lash adjuster capable of preventing noises during starting an internal combustion engine due to air mixture because of oil leakage of a high-pressure chamber.SOLUTION: When a lash adjuster 10 is assembled in a mounting hole 61 of a cylinder head 60, pins 51 exist between the cylinder head 60, a plunger 21 and a body 21, and are engaged with them. Thereby, these three members are restrained from relatively rotating, and therefore, a pin insertion hole 11e is formed so that an introduction hole 21e and a return hole 21g are positioned on an upper side in a gravity direction than a liquid face of oil retained in a separator 31 or a reservoir chamber 21c, so as to prevent the oil retained in the separator 31 or the reservoir chamber 21c from being leaked to outside via the introduction hole 21e or the return hole 21g. Accordingly, noises during starting an internal combustion engine due to air mixture because of oil leakage of a high-pressure chamber 11b can be prevented.
摘要翻译：要解决的问题：提供一种间隙调节器，其能够防止由于高压室的油泄漏而由于空气混合而启动内燃机期间的噪声。解决方案：当间隙调节器10组装在安装孔61中时气缸盖60，在气缸盖60，柱塞21和主体21之间存在销51，并与它们接合。因此，这三个构件被限制在相对旋转的位置，因此形成销插入孔11e，使得引导孔21e和返回孔21g位于重力方向上方比保持在其中的油的液面分离器31或储存室21c，以防止保留在分离器31或储存室21c中的油经由引入孔21e或返回孔21g而泄漏到外部。因此，能够防止由于高压室11b的油泄漏而引起的空气混合而起动内燃机时的噪音。
