Spray heads for use with desuperheaters and desuperheaters including such spray heads. One example of a spray head includes a main body having an exterior surface and defining a central passage, the main body adapted for connection to a source of fluid, at least one entrance port formed in the main body along the central passage, and at least one spray nozzle arranged adjacent the exterior surface of the main body. The spray head also includes a plurality of flow passages, each of the plurality of flow passages providing fluid communication between the entrance port and an exit opening of the spray nozzle. A first one of the plurality of flow passages follows a first non-linear path and has a first distance, and a second one of the plurality of flow passages follows a second non-linear path and has a second distance different from the first distance.

A nozzle includes a shell, a distributor, a panel and a collar. The distributor is inserted in the shell. The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.

A sprayer includes a nozzle that includes a panel, an operation chamber and an outlet element. The outlet element includes an external tube, internal tubes and outlets. The external tube extends in the operation chamber from the panel. The internal tubes extend in the external tube from the panel. Each internal tube includes tangential passageways. The outlets are made in the panel, in communication with the internal tubes. The distributor is inserted in the operation chamber and includes a disc and an inlet element. The inlet element includes a cylinder, inlets and protuberances. The cylinder extends into the external tube from the disc. The inlets are made in the cylinder. Interior of the cylinder is in communication with exterior of the cylinder via the inlets. The protuberances are formed on the cylinder and inserted in the internal tubes. The barrel includes a water supply tube connected to the inlet element.

A humidifier, for a ventilation system, that includes an atomizer configured to deliver water droplets into a flow of breathing gases and a heating element configured to vaporize the water droplets emitted from the atomizer. The humidifier may be configured to set a target inhalation gas temperature based on internal temperature of a patient. Further, based on inspiratory flow and humidity data about breathing gases upstream of the atomizer of the humidifier, the humidifier may calculate and deliver an amount of water in one or more bursts of atomized water. Based on the target inhalation gas temperature, the humidifier may control a temperature of the heating element.

A spray wand for use with a chemical or chemical formulation in solid form. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has at least one nub, indent and/or external channel or groove on its external surface.

A multi-mode fluid nozzle includes a generally-cylindrical mixing chamber with a stream mode fluid inlet connected to one side of the chamber, a fluid outlet connected to the opposite side of the chamber and a plurality of mist mode fluid inlets connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which fluid enters the mixing chamber such that when the fluid enters the mixing chamber through the stream mode fluid inlet, the fluid exits the fluid outlet in a stream flow discharge pattern, when the fluid enters the mixing chamber through the mist mode fluid inlets, the fluid exits the fluid outlet in a mist flow discharge pattern and when the fluid enters the mixing chamber through the stream mode and the mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.

The present invention discloses a water outlet device, comprising: at least one rotatable driving member, at least one injector, and a main body with a plurality of water outflow passages. The main body comprises at least one accommodating cavity, each of the at least one rotatable driving member is driven to rotate by water flow, and each of the at least one rotatable driving member drives the corresponding one of the at least one injector to rotate in the corresponding one of the at least one accommodating cavity. Each of the at least one injector comprises at least one injection hole, the at least one injection hole is connected to the corresponding one of the plurality of water outflow passages, and a water outflow direction of the at least one injection hole and an axial direction of the corresponding one of the plurality of water outflow passage forms an angle.

A dispensing head with a staged swirling chamber for a dispensing system includes a spraying nozzle including a dispensing orifice and a swirling chamber opening into the dispensing orifice, the swirling chamber including a converging portion, and extending along an axis between an upstream end and a downstream end in the direction of displacement of the product, and an anvil including a core provided with a peripheral wall, that is housed inside the swirling chamber, and forming with the converging portion at least one fluidic path in which the product circulates, the converging portion including an inner wall of the nozzle, the inner wall and/or the peripheral wall of the core being provided with a plurality of steps, each step being defined by a transverse wall that extends in a plane secant to the axis and a longitudinal wall substantially parallel to the axis, the steps forming obstacles in the fluidic path.

A multi-mode fluid nozzle includes a generally-cylindrical mixing chamber with a stream mode fluid inlet connected to one side of the chamber, a fluid outlet connected to the opposite side of the chamber and a mist mode fluid inlet connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which fluid enters the mixing chamber such that when the fluid enters the mixing chamber through the stream mode fluid inlet, the fluid exits the fluid outlet in a stream flow discharge pattern, when the fluid enters the mixing chamber through the mist mode fluid inlet, the fluid exits the fluid outlet in a mist flow discharge pattern and when the fluid enters the mixing chamber through the stream mode and the mist mode fluid inlet, the fluid exits the fluid outlet in a droplet flow discharge pattern.
