Abstract
The liquid is sealed in the lash adjuster so that the volume 'V' of the gas, in the reservoir chamber when the lash adjuster is being produced and the plunger protrudes from the body, is equal to or more than 1.24 times as great as the sum of the volume 'Vo' of the liquid discharged from the high-pressure chamber when the plunger moves downward, and the increase “Vo” in the volume of the liquid that expands, due to heat, when the temperature of the gas in the reservoir chamber is increased from the production temperature to the maximum use temperature, and the ratio of “V” to “Vo+Vo” is equal to or higher than a ratio, which is derived based on the production temperature and the maximum use temperature, when the inner pressure of the lash adjuster increases by 500 kPa at maximum.
