Exhaust-gas recirculation valve
TLDR
An exhaust-gas recirculation (EGR) valve includes a rotary drive as mentioned in this paper, which allows operation of a valve member that can be rotated around a rotational shaft.Abstract:
An exhaust-gas recirculation (EGR) valve includes a rotary drive. The rotary drive includes a cam member that has a cam profile. The rotary drive permits operation of a valve member that can be rotated around a rotational shaft. During the course of a closing movement, the EGR valve can, toward the end of the closing movement, move towards a valve seat in a direction that is generally parallel to a direction of flow through the valve seat.read more

Electronic EGR gas control system
Andho Hitoshi,Teruhiko Minegishi +1 more
Abstract: A curved passage constituting part of an exhaust gas recirculation passage is installed inside a suction passage in the downstream of an electronic control throttle valve, of which initial position is the fully opened position, and an exhaust gas recirculation flow control valve is installed in the cylindrical portion extending coaxially from the curved passage into a suction passage. The control valve is a butterfly valve driven by a motor via a reduction gear mechanism. In addition, the control valve opening is sensed by a sensor and cooled exhaust gas flow is sensed by a flow sensor at the outlet of an exhaust gas cooler, and the control of the control valve is based on these sensor signals.

TL;DR: In this article, a rotary valve is used to drive a brushless DC-motor to directly drive the flow control member of the valve and a torsion spring is connected to apply torque in opposition to rotor displacement from one of the limits of its angular excursion.
Patent
Exhaust gas recirculation control
TL;DR: In this article, a regulating unit senses the pressures in two zones of a recirculation passage to create a control pressure, and a transducer regulates an operating pressure which positions a control valve to provide exhaust gas re-circulation at rates which establish the pressure in the zones necessary to maintain the control pressure equal to a reference pressure.
