    摘要: A brake system having a pressure control valve assembly with an inlet valve in a brake line between a master brake cylinder and a wheel brake cylinder. The brake system is also equipped with a precharging pump and a return pump. A charging valve is disposed in a feed line connecting the two pumps. In phases of brake pressure holding and brake pressure reduction upon traction control, the pumping of brake fluid through the continuously operated return pump by the precharging pump is intended to be suppressed. When the precharging pump and the return pump are driven by a common drive motor, the charging valve, which is embodied as a 2/2-way valve, assures that when the anti-skid system becomes operative an exchange of brake fluid between the precharging pump and the return pump is suppressed. When the traction control becomes operative, contrarily, the valve enables pumping of brake fluid from the precharging pump to the return pump, but only whenever the pressure control valve is switched for pressure buildup.
