Claims

[Scope of utility model registration request]

A wall surrounding the combustion chamber of an internal combustion engine, a hole bored in the wall, a cylindrical plunger slidably fitted into the hole with one end exposed outside the hole, and the pressure receiving surface of the plunger exposed inside the hole. a pressure chamber to accommodate the pressure chamber, a reservoir inside the plunger, a check valve mechanism provided on the pressure receiving surface that allows liquid flow from the reservoir toward the pressure chamber, a pressure chamber spring that biases the plunger in the direction of expanding the volume of the pressure chamber, and the above-mentioned external part of the plunger. A hydraulic lash adjuster for an internal combustion engine, comprising a valve drive mechanism whose exposed end is interlocked with a valve mechanism having a valve head attached to the combustion chamber and a stem for reciprocating sliding thereof.
