Abstract

A method for producing a throttle valve unit, which is contained in a throttle device comprised of two housing halves. A receptacle housing for an adjusting drive mechanism that actuates the throttle valve unit is formed onto the throttle device. The throttle valve unit is produced in one piece in a single operation using an injection molding process in which a frame structure is produced, which encompasses a valve surface on both sides of a valve shaft that has bearing elements.
