Dividing suit helmet with improved visibility in turbid water - using supply of forward flow of clear water in front of helmet vision window

摘要

The arrangement is used for a diving suit helmet(3), partic. for use in turbid water, and improves visibility by maintaining a flow of clear, non-turbulent and bubble-free water in the direction of vision in front of the window(9) in the helmet. The helmet may have a flow tube(5) with outflow opening(11) in front of the window(9) and water inlet(7) behind the helmet, whilst a further, separate inlet(8) with rearward outflow opening(12) is provided to produce a reaction force balancing that of the forward outflow.
