Abstract
A valve suitable for an air spring includes a housing body with a central longitudinal axis and channel. The housing body has a first valve opening fluidically connectable to an air spring volume, a second valve opening fluidically connectable to an air supply, which is fluidically connectable to an air spring volume, and a second valve opening which is fluidically connectable to an air supply. Each valve opening is fluidically connected or selectively connectable to the channel. A pressure limiter is provided to limit the pressure flowing out of the second valve opening, the pressure limiter including a third sealing agent and a second sealing agent associated with the second valve opening and selectively closing an opening, wherein pressurization of at least the third sealing agent displaces the second sealing agent due to the forced coupling such that it closes the corresponding opening or reduces the effective opening cross-section.
