Abstract
Damping valve device having a damping valve body with at least one flow channel, which is closed at least partially by a first spring-loaded valve disk on a first valve seating surface, and a second spring-loaded valve disk, which rises from its valve seat at a higher opening pressure than the first valve disk. One of the cover sides of the first spring-loaded valve disk is held under tension on the first valve seating surface while the other cover side is held under tension on a second valve seating surface, and one of the valve seating surfaces of the first valve disk executes a lifting movement synchronously with the second spring-loaded valve disk.
Claims9
A damping valve device comprising:
- a damping valve body having at least one flow channel;
- a first valve disk which at least partially closes said channel and has opposed cover sides which are spring loaded against respective first and second valve seats, said first valve disk rising from said first valve seat at a first opening pressure in said channel;
- and
- a second valve disk which at least partially closes said channel and is spring loaded against a third valve seat, said second valve disk rising from said third valve seat at a second opening pressure in said channel, wherein said second opening pressure is higher than said first opening pressure;
- wherein said second seat rises synchronously with said second spring loaded valve disk.
