| 摘要 |
A spray nozzle having a spray orifice (16) formed by meeting surfaces (10, 12) of at least first (6) and second (8) members, the meeting surfaces (10, 12) of the members being so shaped that the shape of the orifice (16) formed by their meeting is substantially constant despite any misalignment of the members (6, 8) during their mutual approach. Such a nozzle is particularly applicable to self-cleaning spray nozzles in which the members (6, 8) temporarily come together, but is applicable to embodiments in which the members are adhered to one another.
