摘要： A valve apparatus for prevention of a shocking torque in a clutch mechanism includes a housing having a chamber, the housing including an inlet port for being connected with the master cylinder and an outlet port for being connected with the release cylinder. A valve member is slidably disposed in the chamber to partition the chamber into a first chamber and a second member. The valve member includes a restricted passage connected to the first chamber and the second chamber when the valve member is closed. A first elastic member biases the valve member toward a closed position and a second elastic member biases the valve member in the counter direction of the biassing direction of the first elastic member. A wall member is disposed between the outlet port and the valve member for directing fluid flowing from the outlet port to the valve member. At least one of the first elastic member and the second elastic member is made of a shape memory so that the valve member is biassed by the first elastic member and the second elastic member so as to be opened when the temperature of a fluid flowing into the chamber is under a predetermined value and so that the valve member is biassed by the first elastic member and the second elastic member so as to be closed when the temperature of the fluid flowing into the chamber exceeds a value.

摘要： A composite aluminum member joining process. A chemical film including potassium and fluorine is formed on an aluminum member or a flux including potassium and fluorine is coated on an aluminum member. The coated aluminum member is buried together with a disposable pattern in a predetermined assembled state in a mold including molding sand. Then, molten aluminum alloy is poured into the mold, thereby molding an aluminum alloy cast member. The mold is decompressed through the molding sand, thereby expelling tar-like substances generated when the disposable pattern comes in contact with the molten aluminum alloy, burns and vaporizes, at least from the boundary surface between the disposable pattern and the molding sand to the molding sand disposed around the disposable pattern and preventing the tar-like substances from interposing between the aluminum member and the aluminum alloy cast member made from the molten aluminum alloy. Thus, the tar-like substances are drawn in by suction and expelled at least from the boundary surface between the disposable pattern and the molding sand to the molding sand disposed around the disposable pattern before they are deposited on the surfaces of the aluminum member. As a result, the tar-like substances do not interpose between the aluminum alloy cast member and the aluminum member coated with the chemical film or the flux. Therefore, the aluminum member and the aluminum alloy cast member are joined completely, because the effects of the chemical film or the flux have not been lost.
