Valve, for an inter-process communication container, has a flow channel opened and closed automatically according to the pressure difference between the interior and exterior

摘要

The valve for passing air into and from an inter-process communication (IPC) container has a flow channel through it closed by one or more fluid-tight barriers, preferably working automatically through the pressure difference between the interior and exterior. A pressure spring (38,38') acts on a ball (37,37') to block the passage flow.
