A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

A sprinkler head for attaching to a stem of a sprinkler, the sprinkler head having a round or polygonal shaped perimeter and comprising a directional nozzle array on the perimeter of the sprinkler head, the directional nozzle array comprises a single nozzle or a stack of nozzles each nozzle having an orifice facing a specific radial direction; the directional nozzle array being in fluid connection with a conduit through the stem for providing irrigation in the radial direction; wherein the directional nozzle array is provided with a dedicated regulator independently configurable by the user for regulating water flow in the specific radial direction over a range from zero when fully closed to a maximum range when fully open.

An aerosol actuator has a main body member, a nozzle member defining an outlet opening, and a selector member. The outlet opening defines a fluid flow direction. The selector member is moved to obtain different fluid spray patterns. The selector member is distal to the nozzle member and the fluid flow direction.

A firefighting nozzle comprises an elongated barrel having a inlet opening at one end for engaging a source of fluid under pressure and a discharge opening at an opposite end for engaging a discharge element for dispensing the fluid under pressure. A valve arrangement includes a slide valve element slidably mounted within the barrel for reciprocating movement along the length of the barrel to adjust the flow of fluid through the barrel. The nozzle includes a pistol grip trigger assembly mounted on the barrel that includes a segment gear pivotably for engaging a toothed surface of the slide valve element so that rotation of the segment gear causes reciprocation of the slide valve element. A four-bar linkage arrangement is incorporated between a manually actuated trigger to translate depressing the trigger to controllable reciprocation of the slide valve element. The four-bar linkage provides a mechanical advantage that allows the firefighter to easily control the trigger and thus the fluid discharge from the nozzle.

The invention relates to a spray nozzle comprising an elastomeric tube (1) comprising a proximal end (7) through which a fluid is intended to enter said tube (1), and a distal end (8). The spray nozzle also comprises a slit (9) formed in the elastomeric tube (1) between the proximal end (7) and the distal end (8), for spraying the fluid out from the elastomeric tube (1). The elastomeric tube (1) includes a reinforcing element (10, 11) for limiting deformation of the elastomeric tube (1). By providing a slit in a tube between the proximal and distal ends of the tube, the slit can be sized to provide a broad spread pattern to the spray. The reinforcing element prevents over-expansion or deformation of the elastomeric tube.

A portable, self-contained, hand-held, spray gun system having spray gun with a handle, barrel, trigger, and an interchangeable cartridge containing a sprayable substance which may flow from the cartridge under pressure through a portion of the barrel past a selectively positionable needle valve and out an exit orifice of a nozzle when the trigger is squeezed allowing a user to spray the pressurized contents of the vessel over a selected surface and stop such spraying activity by releasing the trigger all without the need for a separate power source or motorized compressor.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided.

In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.
