油圧式ラツシユアジヤスタ。[Scope of Claim for Utility Model Registration] 1. A hydraulic lash adjuster that is tilted in a rocker arm to absorb the lash generated in the intake/exhaust valve mechanism of an engine; a cylindrical body having an axial recess that is disposed in close contact with each other so as to be freely slidable in the axial direction, and one end of which is open toward the bottom of the rocker arm recess; a high-pressure oil chamber formed within the plunger and the body recess; a droplet oil storage chamber formed within the plunger and communicating with the high-pressure oil chamber at the bottom and communicating with the oil passage in the rocker arm at the top; an urging means for urging the main body and the plunger to separate in the axial direction within the chamber; and a valve means for controlling the flow of oil from the oil storage chamber to the high pressure oil chamber to maintain the oil pressure in the high pressure oil chamber within a predetermined range. A hydraulic latch adjuster comprising: an annular sealing means provided between the main body and the loker arm to prevent oil leakage between the two; 2. The hydraulic lash according to claim 1, wherein the annular sealing means is a rubber O-ring and is disposed in an annular groove bored on the outer periphery of the main body. Ajiastha. 3. The hydraulic lash according to claim 1, wherein the annular sealing means comprises a rubber O-ring and a fluorine resin ring fitted on the outside of the rubber O-ring. Ajiastha. 4. Utility model registration claims 1 to 3, characterized in that the rocker arm is provided with an oil passage communicating with the oil storage chamber, and the oil passage is provided with a vent hole communicating with outside air. Hydraulic lash adjuster as described in any of the above. 5. The utility model registration claim 1, wherein the annular sealing means is a packing having a Y-shaped cross section, and is disposed in an annular groove bored in the inner circumferential surface of the rocker arm recess. Hydraulic latch adjuster.
