A nozzle includes a main chamber defining a first internal space, a first inlet defined in a first end of the main chamber to couple to a material sprayer, a second inlet to receive a solid material into the main chamber, and an outlet defined in a second end of the main chamber. The first inlet upstream from the second inlet to allow a fluid material to enter the main chamber before the solid material. The main chamber configured to mix the solid material with the fluid material.

The invention relates to a system for dropping a liquid, comprising a liquid storage reservoir (2) provided with a liquid outlet area (3) that comprises an outlet nozzle (4) and a dropping hatch (5).

Furthermore, the dropping System (1) comprises means for varying the air pressure in the storage reservoir (2) depending on the level of liquid in the reservoir (2).

The disclosure provides a material layer forming device that can reduce scattering of a raw material blown out from a nozzle to efficiently deposit the raw material on a required portion of a blowout target surface. A fiber layer forming device 1A is a device that blows out short fibers F1 to a blowout target surface (wall surface 4b) and deposits the short fibers F1 on the blowout target surface to form a sheet-like fiber layer F2. The fiber layer forming device 1A includes a nozzle 10 having a blowout region 11c that blows out the short fibers F1. The nozzle 10 further includes a suction region 12c that is close to the blowout region 11c and sucks the short fibers F1 spreading to the outside of the blowout region 11c, among the short fibers F1 blown out from the blowout region 11c.

A spray nozzle with posterior positioned switch includes a body (1), a shaft (2) and a pressing bar (3). The body (1) includes a plug (4) blocking off an inner channel. The plug (4) has a through hole (41) in communication with the inner channel. The pressing bar (3) is hinged on a posterior of the body (1). The shaft (2) extends outside the body (1) and is connected to the pressing bar (3). The body (1) includes a first compression spring (5) to push the shaft (2) forward to block off the through hole (41). A positioning mechanism is disposed between the body (1) and the pressing bar (3). The positioning mechanism is controlled by fingers except for thumb to stop the depressed pressing bar (3) in a case that a handle (11) of the body (1) is held in hand.

Turbulence of the jet ejected from the nozzle hole is suppressed. The nozzle includes a shaft body having a center axis, a liquid guide path located inside the shaft body and extending along the center axis, a liquid chamber disposed at a distal end portion of the liquid guide path the liquid chamber having a nozzle hole. The nozzle hole is located at the distal end portion of the liquid chamber, extending along the ejection axis that extends in a direction different from the center axis. The nozzle has an inlet portion having a smaller diameter toward the downstream, and a guide portion connected to the downstream of the inlet portion to guide the liquid to an opening.

A gas nozzle according to the present disclosure includes a supply hole having a tubular shape and configured to guide a gas and an injection hole connecting to the supply hole. The gas nozzle configured to inject the gas from the injection hole is made from ceramics or single crystal including an oxide, a fluoride, or an oxyfluoride of a rare earth element or an yttrium aluminum composite oxide as a primary component. An arithmetic mean roughness Ra of an inner circumferential surface forming the supply hole is smaller on an outflow side than on an inflow side of the gas.

A spray nozzle assembly for directing thin, straight line, high pressure liquid spray onto moving steel slabs for penetrating and removing scale buildup in steel processing operations. The spray nozzle assembly includes a liquid inlet defined by an upstream strainer and a downstream high impact attachment tube for accelerating liquid flow. A one-piece multi-stage liquid straightening vane segment is disposed within a central liquid flow passage of the nozzle assembly for more effectively reducing liquid turbulence of the high pressure liquid flow with resultant improved control in the tightness of the thin, flat spray panner. The one-piece vane segment further is adapted for efficient assembly and replacement in the spray nozzle assembly without the need for handling and precise alignment of a plurality of individual vane elements.

An electric-powered bulk material dispersing system and method of use. The electric power is provided by a battery system with one or more electric motors to replace traditional internal combustion engines. The electric motor or motors are used to provide pressure to one or more pumps that may be used in conjunction with various tubes, hoses or related conduit and spray nozzles in order to disperse a bulk material such as seed, mulch, compost, chipped wood, grain, hay, fertilizer, herbicide, pesticide, plastic pellets, salt, sand or the like that has been combined or suspended within a fluent material. In one form, the bulk material dispersing system may be used as a bulk hydroseeder.

An aerosol unit for an aerosol dispenser, which aerosol unit comprises an axially oriented body, having a distal inlet part and a proximal outlet part; a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part; and wherein the carrier member comprises through-holes which place the inlet part in fluid communication with the outlet part, and wherein the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

A high efficiency nozzle is designed. The nozzle allows water streams with long-range and high surface area in one system. Suitable transitions in the fluid pathways allow creating water streams that have a robust flow profile. The system allows minimum energy loss whilst maximizing the velocity and surface area. Such nozzles can be used for a variety of applications including but not limited to fire suppression, pressure washing, watering, and other such applications.
