The invention provides for device for clamping a fluidic component which is subjected to a fluctuating fluid pressure, said fluidic component having a downstream end, an opposite upstream end and an outer contour, said device comprising a holder, an elastomeric shaped part and a mating part, wherein the elastomeric shaped part comprises at least one compensating surface, and wherein the at least one compensating surface in the assembled state does not contact the mating part or the at least one projection of the mating part.

The present disclosure discloses an electric dust blower which includes a shell, a control panel, a battery module, a fan, an illumination lamp, and air outlet nozzles, where the shell includes two half shells capable of being spliced together left and right; the battery module is disposed at a lower portion of a mounting chamber; the fan is disposed at a rear portion of an air chamber and is close to an air inlet; the illumination lamp is mounted in a mounting hole and exposed out of a front end face of a main body; and the air outlet nozzles are detachably mounted at and connected to an air outlet.

A cap is configured to couple to a nozzle of a dish washer that is configured to supply air into a tub of the dish washer. The cap includes a lower cap configured to couple to an upper end portion of the nozzle, a flow cover configured to cover a part of the upper end portion of the nozzle, and an upper cap coupled to the lower cap and configured to, based on the cap being coupled to the nozzle, be spaced apart from and positioned above the nozzle and the flow cover. The cap defines a discharge opening configured to discharge air supplied to an inner space of the cap through the nozzle.

A nozzle unit for a reaction molding machine, comprising an inlet channel prepared for connection to a mixing head outlet and comprising a first dispensing nozzle, which is prepared for applying a reactive mixture and which is connected to the inlet channel in a first operating state, a second dispensing nozzle being present, which is connected to the inlet channel in a second operating state and which is likewise prepared for applying a reactive mixture. Further disclosed is a mixing head device for a reaction molding machine having the nozzle unit, to a reaction molding machine having the mixing head device, and to a method for producing a plastic part.

The invention relates to various low flow rate fluidic nozzle inserts having a reverse mushroom-shaped mushroom insert geometry that are useful for a wide range of spraying and cleaning applications. In one embodiment, the present invention relates to fluidic nozzle inserts that are able to perform at low flow rates with geometrical and dimensional limitations. In still another embodiment, the present invention relates to compact fluidic nozzle inserts that provide a manner by which to attain a desired level of performance in a fluidic nozzle assembly for small scale applications at low flow rates.

The invention includes a gas supplier for discharging a gas into a space sandwiched between a substrate and a shielding plate by supplying the gas to a gas discharge nozzle provided in the shielding plate to form a flow of the gas from a central part toward a radially outer side of the substrate. This gas supplier is controlled such that a flow velocity of the gas into a discharge space at a peripheral edge part of the substrate becomes larger than zero.

In processing a peripheral edge part of a substrate by a processing liquid, upward scattered liquid droplets may be produced. Accordingly, in the invention, the processing liquid is caused to land on the peripheral edge part of the substrate from a discharge port while the discharge port is positioned to a bevel processing position lower than an eaves part of a cup in a vertical direction with the peripheral edge part of the substrate covered vertically from above by the eaves part. Thus, the eaves part collects upward scattered liquid droplets. As a result, the re-adhesion of the upward scattered liquid droplets to the substrate and the scattering thereof to a surrounding atmosphere are suppressed.

The invention includes an upper sealing member fixed near a ceiling wall of a processing chamber and a lower sealing member provided movably in a vertical direction below the upper sealing member. A sealed space is formed by moving down the lower sealing member to a lower limit position where an upper end part of the lower sealing member is aligned or partially overlapped with a lower end part of the upper sealing member in the vertical direction. On the other hand, a conveyance space for carrying the substrate to and from a substrate holder is formed by moving up the lower sealing member to a retracted position above the lower limit position.

A nozzle assembly for a fire suppression system is disclosed. In some embodiments, the nozzle assembly comprises a body having an inlet end for receiving a flow of fire extinguishing agent from the fire suppression system at an inlet pressure; a nozzle portion extending from the body and having an interior cavity; and a conical central body located in the interior cavity, extending upstream from a base of the nozzle portion, wherein a plurality of exit orifices are formed in an outer wall of the nozzle portion, in communication with the interior cavity, for vectoring the flow of fire extinguishing agent exiting therefrom.
