ABSTRACT:
A control device has an electronic control unit and at least one proportional solenoid valve with a solenoid and a valve body. A plastic matrix is provided in which the valve body is at least partly embedded for securing the solenoid at the valve body. The control device is manufactured by introducing the electronic control unit and at least one solenoid into the first half of an injection mold. The at least one valve body is introduced into the second half of the injection mold. The first and second halves of the injection mold are then advanced toward one another such that the solenoid and the valve body are assembled to a proportional valve. A plastic material is then injected into the injection mold to form the plastic matrix for securing the solenoid at the valve body.
