Abstract (en)

[origin: EP0505855A1] The invention relates to a hydraulic valve lash adjuster for a desmodromic valve gear of an internal-combustion engine, having at least one piston-cylinder unit, inserted into the force path between a closing cam and an intake/exhaust valve and enclosing a pressure space (80), and a reservoir space (76), the pressure space and the reservoir space being connected via a non-return valve (78), a pressure-relief valve (90) being provided in order to avoid impermissibly high valve-actuating forces if the adjuster is "pumped up". <IMAGE>
