Abstract

An electropneumatic pilot unit for controlling a pneumatic consumer is provided herein. The pilot unit comprises at least two electromagnetic pilot valves. Each of the electromagnetic pilot valves comprises a coil for producing a magnetic flux along a valve axis, an armature which can be moved in the axial direction of the valve axis, a valve seat which can be closed and opened by the armature, and a pneumatic inlet port and a pneumatic outlet port. At least two of the pilot valves lie next to each other with parallel valve axes. Each pilot valve has a port which protrudes towards a common underside for connection to a pilot chamber of the consumer controlled by the pilot valves.
