摘要： Air flowing through a secondary air inducting conduit of a motorcycle is effectively cooled to enhance combustion efficiency of exhaust gas in a catalyzer. A part of the secondary air inducting conduit is exposed to a space behind a front wheel and in front of an engine, and thus acts as a secondary air cooling conduit section for cooling down secondary air flowing through the secondary air inducting conduit.

摘要： A pump casing manufactured by press forming of steel plate and including a volute casing encircling a pump impeller so as to form a fluid path around the pump impeller is disclosed. The cross-sectional area of the fluid path is gradually increased towards a discharge port of the pump casing. The pump casing includes a casing body which is formed at first by press forming a metal plate into a cylindrical cup shape having an opening portion at one side thereof and a closed bottom portion at the other side of the same, and then by press forming the cylindrical cup shaped casing body so as to have a volute portion radially outwardly expanded from a cylindrical surface of the casing body at an axially intermediate portion thereof which radially opposite to the pump impeller, a casing flange outwardly extending from the opening portion and an aperture serving as a suction port at the bottom portion.Since no separate volute member is provided within the pump casing to form the volute portion, the outer diameter of the pump casing can be made small and also the shape of the fluid path in the volute casing can be made smooth.

摘要： A sheet-metal centrifugal pump casing comprising a casing shell having a suction port and being formed of a steel plate by means of deep drawing using a press, and having a suction flange firmly attached to the suction port of the casing shell is disclosed. The centrifugal pump casing further comprises a partition body firmly attached to the inner surface of the casing shell for partitioning a space within the casing shell into a suction chamber and a pressure chamber, and a diffuser which is integrally extended from the suction side end portion of the partition body and which tapers off toward peripheral edge of said suction port so that an axial gap is formed between the end edge of the diffuser and the peripheral edge of said suction port.Since the axial gap is formed between the end edge of the diffuser and the peripheral edge of the suction port, even in the case of the suction flange is acted upon by an external force such as by piping, a deformation does not affect the partition body, thus, problems such as contact between the partition body and the impeller may be completely avoided.
