Abstract

A servobrake for motor vehicles including a control valve which can be actuated by an electromagnet independently of an actuating rod which displaces a valve piston, which electromagnet actuates a third seal seat which makes possible ventilation of a working chamber. The third seal seat is formed on a sleeve which cooperates with the electromagnet, an annular element being provided which is arranged displaceably with respect to the third seal seat and which bears against the sleeve via an interposed elastic or compressible element. The annular element has means for guiding an air flow produced during normal braking in the direction of the working chamber.
