Apparatus according to claim 9, characterized in that it comprises means connected with flat plate means for indicating a predetermined pressure. 11. Claim characterized in that said response means connected to the shielding means comprises a pin fixed to the shielding means extendable outwardly through the casing to indicate the presence of a predetermined gas bladder pressure. The device according to item 9. 12. Claims characterized in that the shielding means comprises spring means mounted in the casing and having a shielding portion overlying the grating means, the shielding means being deformable so as to bring the shielding portion into abutment against the grating means. Apparatus according to paragraph 9. 13. Apparatus according to claim 9, characterized in that the spring means is a bent leaf spring having a portion fixed to the casing wall and a flat shield portion overlying the grid means. . 14. Apparatus according to claim 9, characterized in that the interconnection means comprises mechanical means for interconnecting said valve means and said shield means.
