Abstract

The apparatus contains a capsule with two holes, one of which is connected to a pressure sampling point in the line for gas of dependent pressure and the other to a pressure sampling point in the line for gas of controlling pressure. A diaphragm separates two chambers in the capsule, each of which is connected to one of the holes in the capsule. The flow of gas in the line for gas of dependent pressure is controlled and there is an operating rod which couples the control device to each diaphragm. Roller bearings guide the rod in a horizontal position. There can be a device which elastically connects a piston to the operating rod.
