    摘要： A fuel filter is provided which comprises a manifold 4, a connector element 6, a filter bowl 8, a filter element 110, an inlet shutoff valve 38, 36, an outlet shutoff valve 66, 56, an inlet port 10, an inlet passage 18, an outlet port 12, an outlet passage 60 and a relief valve 100 in which the connector element 6 is fixed to the manifold 4, and the filter bowl 8 is reversibly fixed to the connector element 6. The filter bowl 8 is adapted to reversibly receive the filter element 110 and is so configured that when the filter element 110 is located within the filter bowl 8 and the filter bowl attached to the connection element 6 the filter element 110 divides the space defined by the connector element 6 and filter bowl 8 into an inlet filter chamber 92 and an outlet filter chamber 64. The inlet port 10 mouths through a surface of the manifold 4, and the inlet port 10 and inlet filter chamber 92 are in fluid communication via the inlet passage 18, and the outlet port 12 mouths through a surface of the manifold 4 and the outlet port 12 and outlet filter chamber 64 are in fluid communication via the outlet passage 62. The inlet shutoff valve 38, 36 is biased by a biasing means 68 into a closed configuration which prevents fuel flowing along the inlet passage 18 when the filter bowl 8 is not connected to the connection element 6, and connection of the filter bowl 8 to the connection element 6 causes the inlet shutoff valve 38, 36 to be impelled into an open configuration which allows fuel to flow along the inlet passage 18, the outlet shutoff valve 66, 56 is biased by a biasing means 68 into a closed configuration which prevents fuel flowing along the outlet passage 60 when the filter bowl 8 is not connected to the connection element 6, and dimensioned and configured so that connection of the filter bowl 8 to the connection element 6 causes the outlet shutoff valve 66, 56 to be impelled into an open configuration which allows fuel to flow along the outlet passage 60. The relief valve 100 is biased by a biasing means 68 into a closed configuration in which fuel flowing between the inlet passage 18 and outlet passage 60 passes through the filter element 110, and movement of the relief valve 100 into an open configuration allows fuel to flow between the inlet passage 18 and the outlet passage 60 via the relief valve 100 without the fuel passing through the filter element 110. The relief valve 100 is caused to move into its open configuration when a predetermined fuel pressure is reached within the inlet passage 18 and inlet chamber 92.

    摘要： A fuel filling device (18) for refueling a fuel tank (14) is disposed in the vicinity of an exhaust gas post-treatment device (10). Specifically, the fuel filling device (18) is disposed over a hydraulic pump (11) provided to an engine (9) and at a height position equivalent to the exhaust gas post-treatment device (10). Therefore, the fuel filling device (18) can be heated for a short period of time by the exhaust gas post-treatment device (10) which is exposed to high temperature soon after the start of the engine (9).

    摘要： A fuel filter (2) is provided which comprises a manifold (4), a connector element (6), a filter bowl (8), a filter element (110), an inlet shutoff valve (38,36), an outlet shutoff valve (66,56), an inlet port (10), an inlet passage (18), an outlet port (12), an outlet passage (62) and a relief valve (102, 104) in which the connector element (6) is fixed to the manifold (4), and the filter bowl (8) is reversibly fixed to the connector element (6),
    the filter bowl (8) is adapted to reversibly receive the filter element (110) and is so configured that when the filter element (110) is located within the filter bowl (8) and the filter bowl (8) attached to the connection element (6), the filter element (110) divides the space defined by the connector element (6) and filter bowl (8) into an inlet filter chamber (92) and an outlet filter (64) chamber,
    the inlet port (10) is incorporated in the manifold (4), and the inlet port (10) and inlet filter chamber (92) are in fluid communication via the inlet passage (18), the outlet port (12) is incorporated in the manifold (4) and the outlet port (12) and outlet filter chamber (64) are in fluid communication via the outlet passage (62),
    the inlet shutoff valve (38,36) is biased by a biasing means (124) into a closed configuration which prevents fuel flowing along the inlet passage (18) when the filter bowl (8) is not connected to the connector element (6),
    connection of the filter bowl to the connector element (6) causes the inlet shutoff valve (38, 36) to be impelled into an open configuration which allows fuel to flow along the inlet passage (18),
    the outlet shutoff valve (66, 56) is biased by a biasing means (68) into a closed configuration which prevents fuel flowing along the outlet passage (62),
    the outlet shutoff valve (66, 56) is configured to move into an open configuration which allows fuel to flow along the outlet passage (62) when fuel immediately upstream of the outlet shutoff valve (66, 56) reaches a predetermined pressure, the relief valve (102, 104) is biased by a biasing means into a closed configuration so that fuel flowing between the inlet passage (18) and outlet passage (62) has to pass through the filter element (110),
    and movement of the relief valve (102, 104) into an open configuration allows fuel to flow between the inlet passage (18) and the outlet passage (62) via the relief valve (102, 104) without the fuel passing through the filter element.
