Abstract

Improvements introduced in the object of the main patent number 439,661, requested on july 23, 1975, by: "a brake installation of two circuits by compressed air", whose improvements consist of a throttle valve arranged in the reserve pipe, leading to the trailer coupling, of a two-circuit brake system with two pipes for motor vehicles, the control element of which is constituted by a piston with two annular piston surfaces for taking a differential pressure as a control pulse, characterized in that on the control piston (31) there is disposed a spring (27) subjected to prestressing, whose force acts in the direction of connection of the throttle, and because in this piston there is provided an additional surface (28) that can be subjected to load by the service pressure, whose force resulting from pressure loading acts against the force of the spring.
