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.

Wildfire water-supply hose having a QD nozzle with an outer sleeve adapted to engage a firefighter's backpack water bladder's QD connector. The combination male QD nozzle/female QD system permits rapid and easier bottom-up filling of the bladders without dismounting the tank from the firefighter's back, by inserting the QD nozzle into the female QD fitting on the bottom of the backpack bladder. The QD nozzle tip is long enough to open the internal spring-biased shut-off valve in the female QD connector when inserted. Upon opening the supply line valve, water flows into the backpack bladder until full. The supply valve is closed and the QD nozzle is withdrawn from the bladder female QD connector. Rotation of the QD nozzle outer sleeve controls water flow from stream, to spray to mist. The QD nozzle is also used with other types of nozzles on dual fittings having 3-way valves, e.g., fog nozzles.

A low-flow emitter includes a first housing and a second housing. The first housing includes a first thread portion, and a first passage defined in the first thread portion. The second housing includes a second thread portion, and a second passage defined in the second thread portion corresponding with the first thread portion in a thread connection. Part of the thread connection between the first and second housings is a loose fitting thread connection. A spiral passage is formed along the loose fitting thread connection between the first and second housings. Water flow rate is able to be controlled by a rotation of the first housing with respect to the second housing.

A sanitary fitted element (1) which can be inserted into the water outlet of a sanitary outlet fitting and is held releasably there. A characteristic feature of the fitted element (1) according to the invention is that said fitted element has an adjusting device for changing the clear sectional area of flow of the fitted element (1) and/or the discharge rate, which adjusting device is actuable via at least one control element (8) which is arranged actuably on the inflow side of the fitted element (1) and/or on the outflow side thereof. The fitted element (1) according to the invention can be used in a versatile manner in order to reduce the outlay on production and stock.

In a sanitary outlet unit (1), it is provided that a contact surface (6) is formed on a valve element (4) which is adjustable between an open position and a closed position in a flow path (2), which contact surface (6), in the open position, covers a corresponding, stationary counterpart surface (7) and, in the closed position, frees said counterpart surface (7), such that the valve element (4) is automatically held in the open position by the pressure in the flow path and returns to the closed position in the event of a pressure drop (cf. FIG. 1).

A nozzle for dispensing a fluid having a barrel having a proximal end and a distal end, the barrel having a passage defined by a first internal surface extending between the distal end and the proximal end, and an orifice defined by a second internal surface at the distal end of the barrel, a stem located at least partially in the barrel, the barrel is movable in relation to the stem to switch between a low pressure mode and a high pressure mode, a shaper located around an outer surface of the distal end of the barrel, the shaper being movable in relation to the barrel to switch between a low pressure fog mode and a low pressure stream mode. The nozzle is configured to dispense the fluid in a straight stream or fog in both the low pressure mode and the ultra-high pressure mode. The orifice is also configured to provide flushing capability for the ultra-high pressure mode while operating in the low pressure mode.

A spray nozzle has a nozzle portion at an outlet or downstream end that includes a nozzle body defining an opening therethrough, and a movable stem or pintle at least partially within the opening of the nozzle body. The stem and nozzle body define a gap therebetween to define a fluid passageway for fluid in the nozzle to flow through the nozzle portion and out of the nozzle throughout a range of relative movement between the stem and the nozzle body. The relative movement and the size of the gap may be controllable independently of fluid pressure of fluid within the nozzle. The nozzle body and the stem may define geometries so that the flow area between the stem and the nozzle body does not increase, and may decrease, in the downstream direction. The axis of the spray may be at an angle to the nozzle.

Irrigation nozzles are provided that irrigate a full circle coverage area with different maximum throw radiuses. The nozzle may include two bodies, one nested within the other, that acting together form the full circle coverage area. The two bodies collectively define an annular exit orifice with one of the bodies defining the inner radius and the other body defining the outer radius. A flow restrictable inlet may be used to adjust flow through the nozzle and to adjust the maximum throw radius. The nozzle may also include a flow reduction valve to reduce the throw radius from a maximum distance and may be adjusted by actuation of an outer wall of the nozzle. A deflector for use with an irrigation nozzle is also provided.

An example method that includes receiving, by a computing device, a geometry of the component that includes a plurality of locations on a surface of the component; determining, by the computing device, a respective target thickness of the coating for each respective location of the plurality of locations based on a target coated component geometry and the geometry of the component; and determining, by the computing device, a number of passes or velocity of a coating device for each respective position of a plurality of positions to achieve the respective target thickness for each respective location.
