METHOD FOR PRODUCTION OF A THROTTLE VALVE IN A CONTINUOUS THROTTLE VALVE CONNECTOR

摘要

A peripheral, annular groove (3) is incorporated into a throttle valve connector (2) in a first step. A first die (4) and a second die (5) are then inserted into the throttle valve connector (2) and a first plastic material is introduced into a first cylindrical cavity formed thereby in a molten state and hardened, resulting in a plastic insert (10). The first die (4) and the second die (5) are subsequently removed from the throttle valve connector (2) and a third die (11) and a fourth die (12) are inserted into the throttle valve connector (2). A second cavity (14) is formed therebetween and filled with a second plastic material, whereby a throttle valve (1) is formed and is fixed during the cooling process by shrinkage on the throttle valve shaft (15).
