<p>The inflow nozzle suitable for swimming baths is designed as a two-part spherical body. The latter is stepped in a rotatable manner on a bearing ring and provided with a continuous hole. One spherical body part is rotatable, with respect to the other part, about an axis which runs eccentrically to the axis of the hole. The cross-section of the hole can thus be changed at the transition point between the two hole sections by rotating one spherical body part. Between the two parts is a gap through which air is sucked in from an air line.</p> |
