Package structure of gas pressure control device, has several gas passages formed continuously so that one passage is connected transversely in longitudinal direction to another passage extending in direction of gas breakthrough recess

摘要

The package structure (32) has a gas pressure control device (10) with interchangeable gas pressure regulators (14,20). The gas pressure applied on first pressure regulator is reduced and the gas is forwarded to second pressure regulator. The end elements (34,36) are arranged in gas-tight manner at the sides of the package structure. Several gas passages are continuously formed in package structure such that one gas passage is connected transversely in longitudinal direction to another gas passage extending in the direction of gas breakthrough recess connected to first regulator. Independent claims are included for the following: (1) a housing of gas pressure control device; and (2) a gas pressure control device.
