Abstract

901,534. Pressure gauges. SAMSON AP. PARATEBAU A.G. Oct. 8, 1958 [Oct. 8, 1957], No. 32165/58. Class 106 (2). [Also in Group XXIX] A differential pressure - responsive device for a pneumatic controller comprises a bellows 4 fixed to the end plate 2 of a housing 1. The bellows is subject to external pressure fed via line 7 and to internal pressure fed via line 8. The movements of the base 5 of the bellows 4 are transmitted to the outside of the housing by a rod 9 which at one end rests in a bearing 10 on the base 5 and at the other in a similar bearing 11 carried by a pivoted lever 12, 13. The rod 9 passes loosely through a throttle member 17 carried by a flexible sleeve 19 fixed to a bushing 15 through the base of which the rod extends.
