A pressurized container assembly includes a pressurized container, a valve, and a shearing chamber. A flowable product and propellant are also provided within the container. The propellant is substantially non-soluble in the flowable product. Methods of producing a foamed flowable product using shearing chambers are also disclosed.

A spray nozzle for spraying material includes an outlet, a mixing section, an inlet for the material, and a buffer space for pressurized gas. The mixing section is in fluid communication with the outlet. The inlet is in fluid communication with the mixing section. The buffer space is in fluid communication with the mixing section via two or more separate gas supply channels. The inlet comprises a separating wall configured to divide a flow of material to be sprayed into two separate flow passages prior to entry into the mixing section.

A device for dispensing liquid onto a target area of a vehicle surface is described, and includes a mixing valve that is in communication with a pressurized fluidic supply system via a fluidic distribution system, and a controller. The mixing valve includes an outlet orifice that is disposed proximal to the target area, and the mixing valve includes first and second valve conduits that are fluidly connected to the outlet orifice via a mixing portion. The first valve conduit includes a first control valve, and the second valve conduit includes a second control valve. The fluidic distribution system includes a first fluidic conduit and a second fluidic conduit. The controller is operatively connected to the fluidic supply system, and the first and second control valves.

A dispensing assembly for a snow generator has a fixed structure (4) having a circular opening (5) extending along the longitudinal axis (A1); a rotor (6) extending along the longitudinal axis (A1), which has one free end (7) at the circular opening (5), and is configured to rotate around a rotational axis, preferably coinciding with the longitudinal axis (A1); and a water supply assembly (10), configured to supply water at a given pressure within the fixed structure (4), at the free end (7) of the rotor (6); the free end (7) of the rotor (6) being coupled to the circular opening (5) of the fixed structure (4) so as to delimit, together with the fixed structure (4), an annular gap configured to guide a jet of atomised water towards the outside of the dispensing assembly (2).

The invention relates to a work vehicle (1) comprising an operable arm (10) adapted to handle a tool (A-D) fastened to the free end of the arm, a control unit (4) for controlling the work vehicle (1), a dust control system arranged to distribute water mist with the aim of retaining dust that is created when the tool is used. For efficient dust control, the dust control system comprises a pressure air source (31) and a water pressure source (21), an air duct (33) arranged for the tool (A-D), through which an airflow from the pressure air source (31) can be conveyed, an injection nozzle (26) directed against the airflow in the air duct (33), with which water from the water pressure source (21) can be sprayed into the airflow for atomization of the water into liquid drops, which together with the airflow form a water mist, whereby the air duct arranged for the tool (A-D) is directed, so that the liquid drops form water mist (36) in the surroundings of the tool.

A fragrance dispensing system includes a first and a second container each having a main tube for the expulsion of a fragrance contained therein, and a dispensing device that provides a dispensing path towards an outlet section and that includes a mixing chamber and a first and second auxiliary tubes connected at one end to the mixing chamber. A containing case forms a seat containing the first and second containers, and a cap is configured to be applied on the containing case and houses the mixing chamber, an outlet section for the mixed fragrances and, at least partly, and the first and second auxiliary tubes, each of which has a free end separably connected to one of the main tubes when the cap is engaged to the case.

A flow divider for diverging a fluid includes a main body that includes first and second side surfaces being opposite to each other along a central axis of the main body. The first side surface has a central segment transversely intersecting the central axis, and having an inlet channel recessed toward the second side surface, a generally annular channel surrounding the central segment, recessed toward the second side surface, and spatially communicated with the inlet channel at a junction space, and an inclined segment surrounding the annular channel. A width of the annular channel decreases gradually from a start measurement to an end measurement along a rotational direction with respect to the central axis.

A fast-set, plural component, spray applicator (10) includes a stationary mix chamber (48) to eliminate dynamic metal-to-metal high pressure fluid sealing. The stationary mix chamber (48) mixes the plural components before dispensing the mixed components from the spray applicator (10). The spray applicator includes fluid needles (76, 78) configured to engage and disengage seals to perform the fluid valving. Needles (76, 78) control both fluid and air flow to the stationary mix chamber (48).

A spray device (A) according to the present disclosure includes: a two-fluid nozzle (11) which sprays a mist (91); a spray-device-side gas flow path (12) for supplying a gas to the two-fluid nozzle (11); a gas supply source (17) which supplies the gas to the spray-device-side gas flow path (12); a spray-device-side liquid flow path (13) for supplying a liquid to the two-fluid nozzle (11); a liquid supply source (18) which supplies the liquid to the spray-device-side liquid flow path (13); a pulse-driven liquid flow control valve (14) having a valve opening degree that is adjusted according to a pulse signal to control the flow rate of the liquid in the spray-device-side liquid flow path (13); and a controller (30) which adjusts, in multiple levels, the concentration of the mist (91) sprayed from the two-fluid nozzle 11 by adjusting the valve opening degree of the liquid flow control valve 14.

A curable composition for mechanical foaming has a complex viscosity η* that satisfies the following conditions (A) and (B) in frequency dependence measurement by a rheometer: condition (A): η* at 0.1 Hz and 25° C. is in a range of 1000 to 50000 Pa.Math.s; and condition (B): η* at 10.0 Hz and 25° C. is in a range of 100 to 1000 Pa.Math.s.
The curing form of the curable composition for mechanical foaming is not a moisture curing form.
