  • Patent number: 10954866
    Abstract: A flap device for an internal combustion engine which includes a flow housing with a housing wall which delimits a flow-through duct. The flap device includes a shaft mounted in the flow housing, a flap body rotatably mounted on the shaft, an actuator for the shaft, and a pressure measurement point. The pressure measurement point is arranged in a duct section of the flow housing so that the flap body traverses the pressure measurement point when rotating, and in a region of the flow housing remote from the shaft when viewed in a circumferential direction of the housing wall. A flap surface of the flap body is directed towards the pressure measurement point and is curved so that, in each rotary position, a tangent arranged at the position of the curved flap surface having a shortest distance to an opposite wall surface of the flow housing is parallel thereto.

  • Patent number: 10871111
    Abstract: A control device for an internal combustion engine includes an intake channel with an inlet and an outlet, a control element, an exhaust gas recirculation channel with an opening, a recirculation channel, and a shaft having the control element eccentrically mounted thereon. The exhaust gas recirculation channel enters the intake channel. The opening of the exhaust gas recirculation channel is a valve seat for the control element. The shaft acts as an axis of rotation for the control element. A rotation of the shaft moves the control element between a first end position where the control element throttles the intake channel and a second end position where the control element contacts the valve seat at the opening of the exhaust gas recirculation channel. The axis of rotation is arranged in a plane which passes through the valve seat at the opening of the exhaust gas recirculation channel.

  • Patent number: 10578006
    Abstract: A method for controlling a coolant pump for an engine includes delivering a coolant via a coolant pump impeller into a delivery duct to a pump outlet, and adjusting the delivery based on a position of an adjustable control slide which controls a throughflow cross-section of an annular gap between the coolant pump impeller outlet and the delivery duct. A first pressure chamber on a side of the control slide is filled with a pressurized coolant to decrease the throughflow cross-section and the coolant volume flow delivered to the pump outlet, or a second pressure space arranged on an opposite side is filled with the pressurized coolant to increase the throughflow cross-section and the coolant volume flow delivered to the pump outlet. The control slide is moved into a defined position when the engine is switched off dependent on a coolant temperature and remains in that position until a restart.
