Disclosed is an exhaust gas recirculation (EGR) valve for a vehicle which achieves regulation of the flow rate of exhaust gas introduced into an engine and the flow rate of fresh air. The EGR valve includes a fresh air flow channel, an EGR flow channel connected to the fresh air flow channel and a valve unit configured to open or close the EGR flow channel and to selectively block the fresh air flow channel according to an opened/closed state of the EGR flow channel. The valve unit includes a first valve to open or close the EGR flow channel and a second valve arranged at one side of the first valve at a different angle from an arrangement angle of the first valve. The second valve is moved along with the first valve to selectively interfere with a flow stream of fresh air in the fresh air flow channel.

Exhaust gas recirculation (EGR) valve for vehicle

Disclosed is a vacuum pump for vehicles which reduces noise of exhaust air generated during operation of the vacuum pump.

Vacuum pump for vehicles

An exhaust gas recirculation valve in a vehicle has two valves that are controlled individually by using one driving source. The exhaust gas recirculation valve enables secure operation of a vehicle even if the driving source is out of order. The exhaust gas recirculation EGR valve includes a driving unit having a driving motor for rotating a motor shaft and an interlocking unit for receiving rotational force from the motor shaft. A rod portion moves upon reception of the rotational force. A valve unit at an end portion of the rod portion controls a flow rate of the exhaust gas. A valve housing is coupled to the driving unit as one unit and has an EGR port and a bypass port. The interlocking unit includes a valve return member for rotating the motor shaft forcibly to make the valve unit to move to an initial position.

Exhaust gas recirculation valve in vehicle

The present invention relates to an exhaust gas recirculation (EGR) valve for a vehicle. The EGR valve includes a valve housing connected to an exhaust line for discharging exhaust gas therethrough, having a flow line with an inside area divided for taking and re-circulating a portion of the exhaust gas to a suction manifold, a driving unit on one side of the valve housing, and a valve unit mounted in a flow line of the valve housing for receiving driving force from the driving unit directly to control flows of the exhaust gas flowing through the flow line at the same time individually, thereby making stable control of the exhaust gas flowing through the EGR valve, preventing damage caused by the high temperature exhaust gas, and preventing the exhaust gas from leaking to an outside of the EGR valve.
