The invention is a pressure regulator for gaseous and liquid fluids of the type comprising: a main valve disposed between an inlet and an outlet; a control pressure space, the pressure in which acts on the main valve body and which is preferably connected via a choke with the inlet and via a control valve with a vent; means for setting a desired value for the outlet pressure, which means urges the control valve body against a force due to the control pressure; and means for exerting a force on the main valve body proportional to the outlet pressure and directed against the force exerted thereon by the control pressure. In one embodiment, such a pressure regulator is used in a pneumatic conveyance device for a powdered to granulated bulk material. |
