Title:
GAS CYLINDER
Document Type and Number:
WIPO Patent Application WO/2021/053959
Kind Code:
A1
Abstract:
In a cushion mechanism of a gas cylinder (10A-10C), when the pressure of a gas in a first pressure chamber is less than or equal to a prescribed pressure, a valve body (84) cuts off communication between the upstream side and downstream side of a discharge flow passage (82) by mean of the biasing force of a spring member (86). In addition, when the pressure of the gas exceeds the prescribed pressure, the valve body (84) is displaced to the downstream side of the discharge flow passage (82) against the biasing force, thereby enabling communication between the upstream side and the downstream side of the discharge flow passage (82).
