Abstract

A valve for variable throttling of a hydraulic flow includes a tappet and a guide element in which the tappet is guided for movement in a stroke direction. The valve also includes at least one fatigue-resistant, mechanical member that locally reduces a radial play of the tappet so as to reduce possible valve oscillations.
