Abstract
A brake pressure control valve including a housing, a control bushing secured therein, a control slide and a travel simulator movable relative to the control bushing and having a spring. The travel simulator has a pressure piece which is rounded on its side toward the control slide. Toward the pressure piece, the control slide is also rounded. Between the control slide and the pressure piece there is a force transmitting member having two plane parallel end faces. A centering means surrounding the force transmitting member and embodied like a rubber-elastic bushing centers the force transmitting member relative to the longitudinal axis of the control slide and orients the end faces transversely to said longitudinal axis. The control slide, the force transmitting member and the pressure piece form roller pairs, which during the actuation of the brake pressure control valve enable relative movements between the pressure piece and the control slide without generating notable radial force components.
