Abstract
A valve lash adjuster for vehicles may include a piston having a body and an opening/closing unit. The body has an open surface in a bottom and an oil passage extending from a rocker arm shaft to the open surface, such that oil flows through the oil passage. The opening/closing unit is disposed on the oil passage to selectively open the oil passage depending on a pressure of the oil. A cylinder accommodates the piston. The cylinder slides downward to form an oil chamber between an inner side surface thereof and the piston. The oil chamber contains the oil therein.
