Patent ID: 7418781

Claim:
A method for production of a throttle valve in a continuous throttle valve connector comprising the steps of: machining a peripheral, annular groove into the throttle valve connector; introducing a first die and a second die into the throttle valve connector from both sides, wherein the first die and second die are complementary to each other and, when introduced, form in the region of the annular groove a cylindrical first cavity which, toward a center of the throttle valve connector has a peripheral projection; putting a molten first plastic into the first cavity laterally through at least one of two apertures in the throttle valve connector and curing the first plastic there thereby forming a plastic insert having a peripheral projection; removing the first die and the second die from the throttle valve connector; introducing via the two apertures a throttle valve shaft through the throttle valve connector and the plastic insert at right angles to a longitudinal axis of the throttle valve connector; mounting in the two apertures a first hollow plug and a second hollow plug such that the apertures in the throttle valve connector are closed in a manner complementary to the plastic insert; from both sides, introducing a third die and a fourth die into the throttle valve connector which, between the two of them and the peripheral projection of the plastic insert that is formed and runs toward the center of the throttle valve connector, form a second cavity which surrounds the throttle valve shaft in the form of the throttle valve; putting a molten second plastic into the second cavity through the third die and curing the second plastic there so as to form the throttle valve; and removing the third die and the fourth die from the throttle valve connector.
