    摘要: A bearing chamber (701) includes an interior surface (710) comprising a terminal block (711) defining a keyway (712) and a conduit (713) terminating at the keyway (712) and an oil nozzle defining an internal channel. The oil nozzle includes a base tightly fittable in the keyway (712). When the base is tightly fit in the keyway (712), the internal channel is communicative with the conduit (713) and an orientation of the keyway (712) and a configuration of the oil nozzle are cooperatively established to aim the oil nozzle at a predefined target within the bearing chamber.

    摘要: A showerhead (1) is described, said showerhead comprising:
    - a top plate (2), comprising at least one water inlet (3),
    - a bottom plate (4), comprising a plurality of holes (5) through which the water is delivered,
    - a membrane (6), comprising a disc (7) of predefined thickness (s1) and a plurality of nozzles (13) extending perpendicularly from the disc (7) and inserted inside the holes (5) of the bottom plate.
    The showerhead is characterized in that the membrane (6) comprises a peripheral portion (8) with thickness (s2) greater than the thickness (s1) of the disk (7), suitable for defining a water flow passage (9) from the inlet (3) to the plurality of nozzles (13) between the top plate (2) and the disc (7), and in that the peripheral portion (8) includes a flexible tongue (10) extending into the water flow passage (9) and forming a seal against the top plate (2).
