Airlock with a pneumatic orifice for the vacuum train system

Abstract

The disclosure describes an airlock with a pneumatic orifice, characterized in that the orifice chamber is located inside the tunnel, together with an inactive expansion element made up of a flexible material consisting of an external torus and an internal membrane, which is activated by compressed air produced by compressors placed in a housing.

1 .
