Embodiment Construction

[0023] The control valve according to the invention has figure 1 Housing 10 is shown, which is produced from lightweight metal by die-casting. The control valve is designed as a plug valve, so that the inlet 12 and the outlet 14 are arranged on a cylindrical base body 16 so that they overlap one another. Between the two windows forming the inlet 12 and the outlet 14, a channel 18 is formed on the base body 16, which is surrounded by a valve seat 20 and is used as a valve closing body, not shown in the drawing, as a control body. It can be seated on the valve seat 20 in the closed state of the channel 18 , and the valve closing or control body can be lifted from the valve seat 20 in the control state.

[0024] The control body is fastened to the likewise invisible operating mechanism in the form of a valve stem. The valve stem extends along the central axis of the base body 16 and protrudes through a flange 22 which delimits the base body 16 and has a flange opening 24 for th...

Abstract

The invention relates to a control valve for retrofitting an internal combustion engine, said control valve having a housing (10) with an inlet (12) and an outlet (14); a control body, said control body Sliding in the channel (18) between the inlet (12) and the outlet (14); operating mechanism, the control body is fixed on the operating mechanism; actuator (32), through the actuator The operating mechanism is converted into a moving state, and the actuator is fixed on the housing (10), and a heat shield (26), the heat shield is arranged between the actuator (32) and the between internal combustion engines. The heat shield is usually a separately manufactured component. Provision is made to simplify assembly and production that the heat shield (26) is designed in one piece with the housing (10) of the control valve.

Description

technical field [0001] The invention relates to a control valve for retrofitting an internal combustion engine, said control valve having a housing with an inlet and an outlet, a control body which controls the passage between the inlet and the outlet, an operating mechanism (the control body is fixed on the operating mechanism), the actuator (the operating mechanism can enter the motion state through the actuator, and the actuator is fixed on the housing) and the heat shield (the heat shield is arranged on the between the generator and the internal combustion engine). Background technique [0002] Such control valves are used, for example, as exhaust gas recirculation valves, exhaust valves or wastegate valves. When using electric motor-driven actuators, the components of the actuator are heavily loaded thermally when retrofitted to the internal combustion engine due to heat transfer from exhaust gases or heat radiation from nearby engine components, which can sometimes be...
