Abstract
A brake system for automotive vehicles has a pneumatic brake power booster with two chambers one of the chambers being adapted to be acted upon by a low pressure and the other one by a higher pressure, and at least one of the chambers being adapted to be connected to a pneumatic pump. A device is provided to activate and deactivate the pump in response to the pressure that prevails in the chamber of the brake power booster associated with the pump.
Claims14
A brake system for automotive vehicles comprising:
- a pneumatic brake power booster having a low pressure chamber adapted to be acted upon by a low pressure and a high pressure chamber adapted to be acted upon by a pressure higher than that in the low pressure chamber;
- a pneumatic pump connected to at least one of the chambers;
- means for activating and deactivating the pump in response to a pressure prevailing in the at least one of the chambers to which the pneumatic pump is connected;
- a slip control system;
- and
- an electric motor drivingly connected with the pneumatic pump also drivingly connected with a hydraulic pump associated with the slip control system.
A brake system for automotive vehicles comprising:
- a pneumatic brake power booster having a low pressure chamber adapted to be acted upon by a low pressure and having a high pressure chamber adapted to be acted upon by a pressure higher than the low pressure;
- a pneumatic pump connected to the low pressure chamber on a suction side and to the high pressure chamber on a pressure side;
- means for activating and deactivating the pump in response to a pressure prevailing in the at least one of the chambers to which the pneumatic pump is connected, the means including a pressure responsive valve disposed between at least one of the chambers and the pump;
- and
- a motor drivingly connected with the pneumatic pump.
