摘要: An electropneumatic pressure regulating valve has an electromagnet fastened, as an actuating drive, to a valve housing. At least one work connection and a deaeration connection in the valve housing are guided, respectively, to a work chamber and deaeration chamber arranged inside the valve housing. The work chamber and the deaeration chamber are separated from one another by a valve seat corresponding to a valve tappet as closing element. The valve tappet proceeds from the electromagnet and is movable longitudinally through the work chamber via a movable magnet armature of the electromagnet. To improve the deaeration behavior and to achieve a more precise control capability during deaeration, the valve tappet has a through-hole which is directed longitudinally proceeding from its lower disk face and which opens into a pressure-tight coil interior space within the electromagnet. The coil interior space is sealed against the work chamber by a seal which enables the longitudinal movability of the valve tappet.
