Water-and-air massage-jet formation equipment - has main body connected only to air supply and with ejector nozzle drawing in surrounding water.

摘要

The jet is for use in a whirlpool or bath, having a main body with through passage, and a nozzle head in front of the latter. The body (G) is connected only to a compressed-air feed pipe (Z). When supplied with pressure, it forms with the nozzle head (D) an ejector and mixing nozzle (M), drawing in the surrounding water (W). The passage through the body can form an air Venturi nozzle (10), while the nozzle head has a coaxial Venturi jet nozzle (25). A water inlet (27) is formed between the nozzles. The inner end (26) of the jet nozzle can enclose the free end (11) of the air nozzle, leaving an annular gap forming the water inlet. USE/ADVANTAGE - Simple, low cost water-and-air massage-jet formation equipment greatly reduces risk of choking by dirty bathwater.
