FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed hydraulic lash adjuster consists of housing and spring-loaded sectional rod with shutoff valve in which downwards travel of rod is limited by pack of lockrings installed in dummy groove for grinding tool outlet. Lower coil of conical (parabolic) spring can get into said pack. Filtering element is installed in rod. Lock of filtering element limits upwards travel of rod. Limiting groove in housing is made tapered downwards. Rod has no groove in working part. Shutoff valve is made in form of pull back link together with spring and thrust quick-detachable washer.
EFFECT: reduced overall dimensions of valve mechanism, improved reliability, increased service life, cut down production and service expenses.
