Google saves the day again!

Lash adjusters are used in internal combustion engines with overhead-cam valve train systems. They support the pivot ends of rocker arms while automatically controlling the rocker arm positions to keep them in contact with the camshafts and valves. The range of the hydraulic lash adjuster accommodates engine build tolerances so no adjustment is required during engine assembly and also compensates for variation that occurs during the life of the engine so no service is required. They also provide lubricating oil for overhead components such as the cam⁄rocker arm interface and the rocker arm⁄valve tip interface.

There ya go!

basically it works like this:

the cam lobe pushes down on the arm. the arm pivots on the lash adjuster to push down the valve. if there is excessive clearance between the lash adjuster and the arm, the arm will push down on the lash adjuster side until they make contact, thus the valve does not get pushed open as much as it could get pushed open. This also creates a TICK noise because the lash adjuster doesn't move and the arm is "slapping it" in a sort of way. By performing a valve clearance adjustment, you remove the excessive clearance (put it back into spec) between the arm and the adjuster so the arm has the ability to open the valve as completely as it was designed to.
