Parking and maneuvering valve for trailers having a spring-loaded parking brake

摘要

The invention relates to a parking and maneuvering valve for trailers having a spring-loaded parking brake. The aim of the invention is to produce a braking system without a trailer braking valve. The invention provides a release unit, a parking unit and an emergency brake unit functionally assigned to the two units. The release unit, parking unit and emergency brake unit are interactively connected so that the parking unit convoys the pressure exerted by the reservoir of the trailer by the emergency brake unit or conveys the pressure exerted by the coupling head reservoir by the emergency brake unit to the spring-loaded parking brake system.
