| contd. -4- moving diffuser jet, although it may appear simple, might not be so well controlled as one with a larger suction chamber separately, which can be damped in the way we have done in the past. Such a suction chamber can usually be kept in a place where it is free from dust and road grit, and so can be made a close fit to give air damping.
