Safety valve, pneumatic actuator, and vehicle

A safety valve for a pneumatic conduit (798), the safety valve comprising:

• a valve body (120), arranged in the pneumatic conduit (798), the valve body including a pressure port (122) pneumatically connected to a pressure side (840) of the pneumatic conduit (798) and a release port (124) pneumatically connected to a release side (860) of the pneumatic conduit (798),
• a valve piston (140), arranged in the valve body (120) and axially movable along a valve axis (AV) relative to the valve body (120) between a release-side end position (SP1) on an axial side facing the release port (124) and a pressure-side end position (SP2) on another axial side facing the pressure port (122), and
• a valve piston spring (160) that pushes the valve piston (140) toward the pressure-side end position (SP2), and
• a bypass conduit (150) that extends through the valve body (120) or the valve piston (140) and that permits a release airflow (AF) to flow between the pressure port (122) and the release port (124),
• further comprising a pressure-side gasket (130, 130′, 130″), which inhibits the release airflow (AF) between the pressure port (122) and the release port (124) in an annular gap (146) when the valve piston (140) is in the pressure-side end position (SP2),
• wherein the annular gap (146) is between a circumferential surface (145) of the valve piston (140) and an inner surface (126) of the valve body (120),
• further comprising a release-side gasket (134), which inhibits the release airflow (AF) between the pressure port (122) and the release port (124) when the valve piston (140) is in the release-side end position (SP1) wherein, when the valve piston (140) is in the release side end position (SP1), the release-side gasket (134) is arranged between a release-side end face (144) of the valve piston (140) and a release-side stop (129) of the valve body (120), and extends within an axial extent of the valve body (120) defined axially between the release side end face (144) and the release-side stop (129) in the direction of the valve axis (AV) when the valve piston (140) is in the release-side end position (SP1),
• wherein the release-side end face (144) is defined by a terminal end of the valve piston (140),
• wherein, when the valve piston (140) is in the release-side end position (SP1), the release side gasket (134) directly contacts the release side stop (129),
• wherein, when the valve piston (140) is in the release-side end position (SP1), the release-side end face (144) is axially spaced from the release-side stop (129) toward the pressure port;
• wherein the release port (124) is a first release port (124.1) and the valve body (140) includes a second release port (124.2), wherein the safety valve includes a further release-side gasket, where the release-side gasket and the further release-side gasket combine to seal the first release port and the second release port when the valve piston is in the release-side end position.
