Abstract
A hydraulic lash adjuster for use with an internal combustion engine having an overhead cam, includes a stationary body received within a cylinder head bore and a plunger reciprocal within the body. The plunger includes a central cavity defining an oil reservoir. A passage is formed through the lash adjuster body to place the oil reservoir in fluid communication with the lubrication system of the engine. A pair of metering lands are formed on the exterior of the lash adjuster body adjacent the oil inlet passage to reduce the pressure of the oil in the oil reservoir to prevent pump-up.
