- the filter 26 may also be arranged at a different location. Specifically, the filter 26 may be disposed between the tank 20 and the suction side 21 of the pump 16. As a result, a dirty filter 26 does not hinder a response of the braking device 5.
- a cost-effective design of the brake system 2 is possible because the number of parts required is low. Specifically, valves and accordingly a valve logic can be saved.
- an embodiment of the brake system 2 is possible, which is based essentially on the pump 16, the tank 20, the housing 6 - which forms a cylinder with the piston bore 9 - and the piston 8.
- a pump 16 with greater self-leakage can be used. As a result, the quality promotions to the pump 1 6 can be reduced.
- a pump with greater self-leakage is usually cheaper than a pump with low leakage.
- the brake system 2 can be configured as an integrated unit, in which all or at least most of the components are integrated into a housing 6 serving as a brake housing.
- the operation of the brake system 2 can thus be realized in particular via a speed control of the speed n of the pump 16.
- the invention is not limited to the exemplary embodiments described.
