Slip-controlled brake system, especially for use with automotive vehicles

A slip-controlled brake system for a vehicle having wheels, said system comprising:

• a pedal-actuated brake pressure generator;
• means for sensing wheel rotational behavior of said wheels and for generating signals representative of said wheel rotational behavior;
• electronic circuit means, responsive to said signals representative of said wheel rotational behavior, for generating actuating signals;
• hydraulic valves responsive to the actuating signals and operable to modulate brake pressure to effect wheel slip control;
• an auxiliary pressure pump for delivering pressure fluid to said hydraulic valves during wheel slip control;
• a hydraulic circuit interconnecting said generator and said hydraulic valves and said auxiliary pressure pump;
• and
• pressure attenuation means, which are:
• (a) displaceable in response to hydraulic pressure fluctuations,
• (b) disposed in said hydraulic circuit in the vicinity of said generator, and
• (c) operable to attenuate pressure pulsations within said hydraulic circuit caused by said hydraulic valves and caused by said auxiliary pressure pump,
• wherein said pressure attenuation means include two high pressure elastomeric tubular sections with a diaphragm member integrated between.
