Abstract
An improved nozzle for use with a tub, such as a redwood tub, having a side wall provided with an opening therethrough. The nozzle comprises a nozzle body receivable in the wall opening and having a main water-receiving bore therethrough. A flow control valve is in the main bore and is manually adjustable at the outlet end of the main bore. The nozzle body has a secondary bore provided with a one-way check valve therein. The secondary bore communicates with the main bore to allow air to pass into the water by suction to aerate the water as it flows into the tub. A flow regulator member is adjustably mounted on the nozzle body near the outlet end of the main bore for controlling the flow of air into the water flow. Several embodiments of the check valve are disclosed.
Claims9
A fluid nozzle for a water tub comprising:
- a unitary nozzle body having means defining a main bore therethrough, said nozzle body adapted to receive a flow of water through the main bore;
- means carried by the main bore defining means and within the main bore for adjustably controlling the volume rate of flow of water therethrough, there being means coupled with the control means, independent of said main bore defining means, and accessible at the outlet end of the main bore for adjusting said control means, said nozzle body having a secondary bore adjacent to the main bore;
- a spring-biased check valve in the secondary bore for permitting a flow of air in one direction therethrough, said body having a third bore placing the secondary bore in fluid communication with the main bore near the outlet end thereof, the third bore having one end in fluid communication with the main bore at the outer periphery of the main bore;
- means coupled with said nozzle body for adjusting the volume rate of flow of air through the third bore, whereby air can flow past the check valve and into the main bore to aerate the water flowing therethrough.
