ABSTRACT:
An apparatus having a self-aspirating pump, with which, in a traction control mode, pressure fluid can be aspirated through an intake line from a pressure fluid supply tank of a master brake cylinder. Located in the intake line is a control valve that assumes its preferred blocking positoin and can then be switched into its open position by a pressure pulse generated by the pump, through a control line. This open position can be switched whenever a control valve, located in the brake line of the master brake cylinder, is switched by an electronic control unit of the control apparatus out of its preferred position thereby connecting the master brake cylinder to the wheel brake cylinders into another position, thereby carrying pump pressure to the control valve. Aspiration of pressure fluid from the supply tank is thus avoided upon pump startup with undesirable feeding. This prevents the production of noise from the pumping of pressure fluids into the master brake cylinder.
