    摘要： A pump assembly comprises an inlet (10) having an open end, an outlet (12) having an open end and a housing (11) having an inlet aperture (31) in fluid connection with the inlet (10) and an outlet aperture (32) in fluid connection with the outlet (12). A rotor (37) is located within the housing (11) and shaped to form with an interior surface of the housing at least one chamber (28a, 28b) that on rotation of the rotor (37) conveys fluid from the inlet aperture (31) to the outlet aperture (32). The housing (11) carries a seal (24) located in the inlet (10) and urged into contact with the rotor (37) to prevent the passage of fluid past the rotor (37) from the outlet (12) to the inlet (10). The inlet (10) and the outlet (12) have respective centre lines that are parallel to one another and normal to the axis of the rotor (37). The outlet (12) forms a guide path for linear movement of a mould core (52) for forming the outlet (12) and the outlet opening (32) and the outlet aperture (32) being so orientated that the direction of opening of the outlet aperture (32) does not face away from the open end of the outlet (12). This allows the outlet (12) and the outlet opening (32) to be formed using a single simple mould core (52) travelling in a linear path.
