Abstract: A nozzle can produce bubbles from a liquid saturated with gas desirable in bathing. The nozzle can have a housing forming a first chamber for receiving a liquid. The nozzle can have an intermediate chamber located between the outlet of the first chamber and the inlet of the outflow passage. The nozzle can have a generally cylindrical structure enclosing the outflow passage and having a central longitudinal axis extending into the outlet of the first chamber. The intermediate chamber can have a first wall generally perpendicular to said axis and surrounding the outlet from the first chamber and second wall spaced from said first wall and generally parallel thereto and surrounding the inlet to the outflow passage.

Abstract: This disclosure relates to nozzles, systems containing them and methods of using them. In particular, this disclosure relates to nozzles that can produce bubbles from a liquid saturated with gas. The nozzles can produce micro bubbles which are desirable in bathing.
