| 摘要 |
The invention relates to a discharge nozzle for the discharge valve of a whirlpool tube having a water inlet duct and an air inlet duct, in which the water stream and air stream are mixed together as the result of an injector effect. In order to improve the hydropneumatic massaging effect, the water inlet duct is disposed axially and centrally with respect to the inner surface of an outer disk-shaped distribution element and is open to a radially outwardly leading circular discharge duct formed between the outer distribution element and an inner disk-shaped distribution element. The air inlet duct discharges air into a ring interstice defined between the inner distribution element and the tub wall or the valve body or valve housing of the discharge valve.
