Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to affix the support component to the additional component. The support component comprises a tube made of plastic to accommodate the screw in a friction and positive fit, wherein the tube comprises a thermoplastic foam. The screw comprises a blunt-edged screw thread. The foam is compacted as the screw is driven into the tube. The present disclosure further relates to a corresponding screw and to a method of connecting a support component to an additional component using the screw.

Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to fasten the support component to the additional component. The support component has a tube made of thermoplastic foam to accommodate the screw in a friction and positive fit. The screw has a blunt-edged thread, enabling the screw to compress the foam in the tube as it is driven in. The ratio of the inner diameter of the tube to the diameter of the screw depends on the degree of foaming of the tube and decreases as the degree of foaming increases. In comparison to conventional screws, the threads of the screw of the present disclosure penetrate less deeply into the foam or they displace it, preventing damage to the tube while enabling a tight fit.

Abstract: An exhaust gas valve device for an internal combustion engine includes an actuator, an actuator housing, a valve rod configured to be moved in a translational direction via the actuator, a control body arranged on the valve rod, a flow housing comprising laterally delimiting walls, a valve seat arranged in the flow housing, and a shielding element. The valve seat is configured to have the control body be lowered onto and lifted off of the valve seat. The shielding element comprises a base which comprises an opening configured to have the valve rod extend therethrough. The shielding element is configured to extend from the actuator housing into the flow housing, to have a pot shape, and to radially extend to the laterally delimiting walls of the flow housing.

Abstract: An arrangement for attaching a control valve to a flow channel housing of an internal combustion engine which includes an insertion housing part which projects into the flow channel housing. The arrangement includes an actuator housing, an actuator arranged in the actuator housing, a housing plate which rests on the flow channel housing, screws, and a collar flange which radially surrounds the housing plate. The insertion housing part extends on a first side of the housing plate and the actuator housing extends on a second opposite side of the housing plate. The collar flange comprises a screw hole pattern arranged thereon and through-holes arranged therein. The screw hole pattern corresponds to a connecting bore pattern of the flow channel housing. The control valve is attached to the flow channel housing via the screws being inserted through the through-holes of the collar flange.
