  • Patent number: 9212774
    Abstract: A connector to connect a fluid path to a fuel tank includes a main portion made of a synthetic resin through which a gas produced from fuel hardly passes, and a shell formed outside the main portion and made of a synthetic resin through which the gas passes easier than the main portion and which can be melt-bonded to the outer surface of a fuel tank. The main portion includes a flange part in the outer periphery. The shell has a wall section for a melt-bonding portion which extends around from the top surface side of the flange part and covers the bottom side of the flange part. The undersurface of the flange part is provided with an inclination having the peripheral edge side of the flange part upside thereof.

  • Publication number: 20130127159
    Abstract: A fuel tank plumbing structure adapted to be inserted into a through-hole formed in a wall portion of a fuel tank, includes a first pipe adapted to be attached to the fuel tank; a second pipe coaxially connected to the first pipe; a flexible locking piece protruding in one of either the first or second pipe; a locking portion formed in the other of the first or second pipe, and locking the locking piece; and a lock member to be displaceable between a predetermined first and second position. While the lock member is separated from the locking piece in the first position to allow an engagement and a disengagement of the locking piece and the locking portion, the lock member abuts against the locking piece in the second position to prevent the disengagement of the locking piece from the locking portion.

  • Patent number: 7172015
    Abstract: A heat exchanger used in a screw air compressor has a low temperature chamber through which low temperature fluid flows and a high temperature chamber through which high temperature fluid flows. The low temperature chamber and the high temperature chamber are separated by a partition plate. The high temperature chambers and the low temperature chambers are alternately arranged in layers, so that the low temperature chambers are disposed at both ends in a layered direction. Additionally, the flowing direction of the low temperature fluid in the low temperature chambers and the flowing direction of the high temperature fluid in the high temperature chambers are substantially orthogonal to each other.
