摘要： When a failure occurs in synchronizing mechanism, an intake air throttle valve is rotated in a direction that is opposite from a normal operational time valve closing direction, so that an arm of a driven plate contacts a throttle valve side stopper to stop rotation of the intake air throttle valve. Thereafter, when a low pressure EGR valve is rotated from a full close position to a full open position, an EGR valve side stopper contacts the arm of the driven plate to stop the low pressure EGR valve. A rotational angle of the EGR valve is sensed with a sensor and is outputted to an ECU. The ECU determines that a failure mode is set when a valve angle sensed with the sensor coincides with a rotation stop position of the EGR valve.

摘要： An object of the invention for a valve device having an inclined valve body is to suppress pressure loss at a valve opened condition to a smaller amount. The valve body is composed of a disc shaped valve member for closing a fluid passage, a first supporting portion provided at an outer periphery of the valve member and connected to a first shaft member, and a second supporting portion provided at another outer periphery of the valve member and connected to a second shaft member. The valve body is formed of a press-molded metal plate and forms a Z-shape when viewed in a direction parallel to a surface of the valve member.

摘要： An EGR control valve is driven by an actuator so as to control EGR amount by changing its opening degree. An EGR cooling device is provided in an EGR passage for cooling down EGR gas. A bypass passage is provided to the EGR passage, so that EGR gas may bypass the EGR cooling device. A switching valve is provided in the EGR passage for switching EGR mode from a hot EGR mode in which the EGR gas flows through the bypass passage to a cold EGR mode in which the EGR gas flows through the EGR cooling device, or vice versa. A converting mechanism is provided between the EGR control valve and the switching valve, so that the switching valve is driven by the actuator from its hot to cold switching position (or vice versa) when the EGR control valve is driven by the same actuator in a small angular range.

摘要： A converting mechanism is provided between an EGR control valve driven by an actuator and an intake-air valve for generating negative pressure, so that the intake-air valve is also driven by the actuator. The converting mechanism has a cam plate rotated together with the EGR control valve and an arm rotated together with the intake-air valve. A cam groove formed in the cam plate is engaged with a driving pin of the arm. The intake-air valve is held at its maximum valve opening position, when the EGR control valve is rotated in a first angular range, while the intake-air valve is rotated from the valve opening position to a maximum valve closing position when the EGR control valve is rotated in a second angular range.
