A hydraulic lash adjuster for a valve train of an internal combustion engine is provided, with the hydraulic lash adjuster including a circular cylindrical housing in which a piston ( 22 ) is arranged for axial displacement, and further including a one-way valve ( 31 ) with a closing body ( 32 ) that can be brought to bear against a valve seat ( 28 ) of the piston ( 22 ) for sealing a through-opening ( 24 ). The closing body is surrounded by a valve cap ( 35 ) and loaded by a compression spring ( 33 that is supported with a first end on the closing body ( 32 ) and with a second end on the valve cap ( 35 ). The closing body ( 32 ) has an approximately spherical, convexly vaulted bearing surface ( 34 ) for sealing contact on the valve seat ( 28 ) and deviates in shape from a ball shape.
