Filed:

Apr 28, 2003

Appl. No.:

10/424520

Inventors:

Michael Charles Stephenson - Dallas TX, US

International Classification:

E04H004/16

US Classification:

210169, 210238, 2104162, 4490

Abstract:

A portable pool cleaning system for the remote cleaning of a swimming pool including a housing and a base. A motor is connected to the housing and is attached to a high pressure pump wherein the pump includes both intake and ports. The first tubing is connected to the intake port and the opposite end is inserted into the swimming pool for the transportation of water from the swimming pool to the pump. A second tubing is connected to an output port of the high pressure pump with the opposite end of the second tubing placed into the swimming pool and attached to a self-propelled cleaning device. The self-propelled cleaning device uses a high pressure water stream as a scrubbing function. The motor is connected to a timer which is connected to a power source. The timer initiates the activation and deactivation of the motor and the self-propelled cleaning device. A means for attaching the base and portable pool cleaning system to the periphery of the swimming pool is also included.

Abstract:

Provided is a dual spray nozzle tip assembly having a geometry that is split into several sub components to enable robust manufacturing and assembly of the resulting nozzle. The nozzle tip assembly is configured to be attached to a device configured to provide a pressurized fluid and gas therefrom. The nozzle tip assembly comprising an elongated body defining a fluid lumen and at least one gas lumen between a distal end and a proximal end. The elongated body including at least an attachment profile, a straight portion, and an outlet region. The outlet region defines a shear nozzle in communication with the fluid lumen and at least one gas outlet in communication with the at least one gas lumen, the outlet region is configured to direct pressurized gas from the at least one gas outlet and to produce a desired spray pattern from the shear nozzle.
