Abstract
A pressure modulator for an antilock braking system (ABS) has a housing with a hydraulic inlet and a hydraulic outlet, the hydraulic inlet and outlet interconnected via a hydraulic line; a volume accumulator arranged to be opened against a spring force of a spring element and which increases a volume of the hydraulic line during an activated anti-lock function. A linear drive is provided with a rotor bar, where a displacement movement of the rotor bar effectuates an opening of the volume accumulator. The spring element is supported at least indirectly on the housing and the rotor bar, where the spring element is disposed in the rotor bar.

A pressure modulator for an antilock braking system (ABS), comprising:
- a housing with a hydraulic inlet and a hydraulic outlet, where the hydraulic inlet is connected to the hydraulic outlet via a hydraulic line;
- a volume accumulator arranged to be opened against a spring force of a spring element, where the volume accumulator increases the volume of the hydraulic line during an activated anti-lock function;
- and
- a linear drive arranged with a rotor bar, where a displacement movement of the rotor bar effectuates an opening of the volume accumulator;
- wherein the spring element is supported at least indirectly on the housing and the rotor bar.
A hydraulic brake system having an anti-lock function, comprising
- a master cylinder that generates a hydraulic pressure and is connected to a wheel brake in a hydraulically communicating way via a hydraulic line;
- and
- a pressure modulator;
- wherein the pressure modulator comprises:
- a housing with a hydraulic inlet and a hydraulic outlet, where the hydraulic inlet is connected to the hydraulic outlet via a hydraulic line;
- a volume accumulator arranged to be opened against a spring force of a spring element, where the volume accumulator increases the volume of the hydraulic line during an activated anti-lock function;
- and
- a linear drive arranged with a rotor bar, where a displacement movement of the rotor bar effectuates an opening of the volume accumulator and where the spring element is supported at least indirectly on the housing and the rotor bar.
