Pneumatic multi-valve device and production method

Abstract

A pneumatic multi-valve device includes a housing () having a housing main body () with a plurality of electromagnetic valve actuators (), each having coil elements () arranged stationary in the housing (), a core () arranged in the housing (), and armature elements () displaceable along a displacement axis (V) in the housing () in relation to a pneumatic connection () of the housing (). Displacement axes (V) of the armature elements () are oriented parallel and the pneumatic connections () are arranged adjacent to each other. The cores () each have a venting bore () connected to a venting collection channel (). The venting collection channel () is on the side of the cores () facing away from the connection housing side (), and is bounded on the housing back side () by a housing cover () fastened to the housing main body (). The venting collection channel is connected to a venting opening of the housing (), which venting opening is arranged on a housing side different from the housing back side (), in particular on the connection housing side () having the pneumatic connections (). The housing cover () is fixed to the housing base body () via an air-tight welded connection (), in particular an ultrasonic or laser welded connection.
