Abstract
The invention relates to a master cylinder, in particular for a controlled motor vehicle brake system, including a first and a second piston which is displaceable in a housing and has a captive spring, a first end of the spring bearing at least indirectly against the piston and a second end thereof against a sleeve which is displaceable with respect to the piston and the movement of which with respect to the piston is limited by a pin provided on the piston and by a stop washer, the stop washer being arranged on a free end of the pin. In order to avoid impact noise upon rapid release of the brake, the stop washer of the first piston has a device for the damped abutment of the sleeve.
