Abstract
A valve block for an air suspension system for a vehicle, including a pressure supply connection and at least one load connection it is to be achieved that a pre-assembly of an air suspension valve block can be avoided without having to utilize an air dryer on a granulate basis during the filling of the air suspension system. This means that a subsequent filling of a completely assembled air suspension system is possible. This is achieved by a filling connection with integrated filling valve.
Claims14
A valve body comprising:
- a filling connection housing configured to form a filling connection to an external filling apparatus, wherein the filling connection is configured to selectively provide compressed air;
- a pressure supply connection;
- a plurality of load connections, wherein each load is configured to be filled with the compressed air from either the filling connection or the pressure supply connection;
- and
- a sealing piston configured to be displaced axially between a closing position and an opening position, wherein a spring component, arranged between the sealing piston and a spring holding ring, is configured to urge the sealing piston into the closing position, the sealing piston is guided by holding components fixed directly on a housing of the filling connection, and the holding components are formed as self-holding pressed-in parts and have sawtooth structures on their outer sides.
