Abstract: A diaphragm valve for a vehicle includes: a diaphragm chamber having an upper chamber and a lower chamber divided by a diaphragm and communicating with a valve inlet and a valve outlet. The upper chamber has a nipple in which a fluid flows or from which a fluid is discharged, and the lower chamber has a chamber opening port at a lower end thereof. A valve rod is coupled to the diaphragm and extends toward the valve outlet. A valve head is provided at a position corresponding to an end of the valve rod and has a wider cross sectional area than the valve rod. The valve head closes the valve outlet when the valve is closed, and closes the chamber opening port when the valve is open.

Abstract: An auxiliary cooling system which is provided separately from an engine cooling passage in a vehicle provided with a turbo engine. The auxiliary cooling system includes a first line which connects a radiator and an intercooler to each other and on which an electric water pump is installed. A second line connects the intercooler and an intake manifold. A third line connects the intake manifold and the radiator, and a bypass valve selectively directly transfers cooling water, heated while passing through a turbine housing provided on a path of the third line, to the radiator or transfers the cooling water to the radiator via an engine block or a heater. Cooling water discharged from the intake manifold passes through an ETC (electronic throttle control) unit and thus reduces a temperature of intake air passing through the ETC unit.

Abstract: A valve device of a turbocharger includes: a valve seat disposed on an entrance of a fluid passage divided into at least two branches, and an opening/closing valve coupled to a rotary shaft rotatably disposed adjacent to the valve seat. The valve seat has a contact surface which is flat and a dividing section which extends across the entrance and divides the entrance into two entrance sections. The opening/closing valve closes the entrance of the fluid passage disposed in the valve seat. The bottom surface of the opening/closing valve is in surface contact with the contact surface of the valve seat. The central portion of the opening/closing valve corresponding to the dividing section is spaced apart from the dividing section at a predetermined distance.
