  • Exhaust gas recirculation device with integral drive module for an internal combustion engine
    Patent number: 6651634
    Abstract: Exhaust gas recirculation device for controlling recirculation of exhaust gases to the intake channels of an internal combustion engine. The device has a housing containing a rotary slide valve having a disk-shaped element attached to a rotatable drive shaft. The disk-shaped element controls flow of exhaust gas through openings in a stationary control element. A drive module is mounted on the housing for turning the rotary slide valve.

  • Balanced valve control member for exhaust gas recycling
    Patent number: 5701874
    Abstract: A control valve for the recycling of exhaust gas from an exhaust gas channel to an air inlet channel of the engine, wherein a valve member of the valve opens and closes a valve opening between the exhaust gas channel and the air inlet channel. An electromagnetic control unit acts on the valve member to open the valve and a spring biasses the valve to a closed state. The valve member has a closure portion for closing the valve and is formed with a balancing section spaced from the closure portion and formed with a cross-sectional area equal to that of the closure portion so that the air pressure in the inlet channel applies equal and opposite forces on the balancing section and the closure portion whereby the valve is balanced and not subject to pressure variations in the air inlet channel, such as due to turbocharging.
