Spray apparatus for bottle cleaning machine
The arrangement incorporates a tube (1) to which cleaning fluid is fed under pressure. A shaft is mounted at a short distance from and parallel with the tube. The shaft is supported by bearing blocks (3) on the tube. Spray holes (5) in the shaft are connected to the tube by plastics seals (6) which are mounted between the shaft and the tube. The seals (6) have a tubular shape and have protruding parts which engage with openings in the tube. There is an annular space (7) between the protruding part and the outside of the seal, in which a ring-shaped elastomer lip seal (8) is mounted. The lip seal provides a fluid seal between the tube (1) and the seal (6).
