There is provided a cleaning apparatus for unclogging an irrigation emitter inlet filter by dislodging or crushing or breaking a trapped solids. In some embodiments, a ram pushes the trapped solids out of a fluid inlet of the emitter. In other embodiment, a constriction provided for retaining a particle has a changeable interior cross section. By changing the cross section of the constriction, the constriction is unclogged. In alternative embodiments the filtration member may include two rigid members moving in relation one to the other or the filtration member may be elastic. In further alternate embodiments the cleaning may be activated automatically or manually.

A coating agent pump for conveying a coating agent, in particular a paint, an adhesive or a sealing agent. The coating agent pump comprises a pump inlet for admitting the coating agent to be conveyed and a pump outlet for delivering the coating agent conveyed by the coating agent pump. In addition to the pump inlet and the pump outlet, a cleaning opening is provided for cleaning the coating agent pump of the coating agent situated in the coating agent pump.

Apparatus for the delivery of fluid products comprising a base, a base support associated thereof, a plurality of dispensing units to dispense the fluid products contained in containing receptacles. The dispensing units are disposed on a platform rotatable with respect to the base support so as to assume at least a first position in which the fluid products can be delivered from the receptacles toward a container. The apparatus also comprises sliding means which allow the rotation of the platform. Rapid connection means are provided so as to achieve the connection of the base support with the base and/or with the sliding means in order to achieve a selective stable coupling and to prevent a reciprocal vertical movement.

A liquid dispenser. The dispenser includes reversible modular components to define selective removability and rearrangement between them and a base structure such that one or more sheets of a passing liquid-receiving substrate may receive such liquid through interchangeable liquid-dispensing orientations. The removability features include tool-free operation to facilitate quick insertion and removal of the modular components that include at least a liquid-dispensing valve assembly and a seal that is selectively engageable with the valve assembly to protect liquid-dispensing nozzles of the valve assembly from becoming clogged with residual dried liquid during periods of inactivity of the liquid dispenser. Selective movable cooperation or attachment between the modulesas well as between the modules and the base structurefacilitates flexible configurations of the dispenser, including top-down and bottom-up liquid-dispensing orientations.

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.

A color changer is provided that includes a base module having at least two input channels and at least one output channel for paint material connectable to each of the at least two input channels. The color changer further includes at least two paint valves, each of the at least two paint valves corresponding to one of the at least two input channels and configured to close the corresponding input channel and to be opened by the application of air pressure, and at least two pilot air channels, each of the at least two pilot air channels corresponding to one of the at least two paint valves and configured to convey air pressure to the corresponding paint valve to open the corresponding paint valve. Each pilot air channel includes a blow hole and a closing device for closing the blow hole.

A rotary atomizing head (7) is provided with an outer peripheral surface washing passage (14) open onto anatomizing head outer peripheral surface (13) for causing wash fluid supplied from a feed tube (6) to flow out into an annular clearance (20) between the rotary atomizing head (7) and a shaping air ring (15). An outflow opening (14C1) of an outflow passage (14C) constituting the outer peripheral surface washing passage (14) is provided in a position closer to the backside into the annular clearance (20) by a length dimension (L1) than a front end surface (17A) of a front ring section (17) constituting the shaping air ring (15). Further, the outflow opening (14C1) opens to the annular clearance (20) in an angle (1) that is an acute angle to the atomizing head outer peripheral surface (13).

A coating apparatus includes: a nozzle having a nozzle front end configured to spray a coating solution and a head configured to store the coating solution; a movement axis configured to cause the nozzle to move back and forth in a straight line; a rotating connection member configured to connect the movement axis with the nozzle and allow the nozzle to rotate; a stage disposed under the movement axis; and a cleaning means disposed at an end of the movement axis, and having a nozzle front end insertion unit in a concave shape of the nozzle front end and a base fixing the insertion unit, wherein the nozzle is fixed in a normal direction of a surface of the stage by the movement axis, moves back and forth in an extension direction of the movement axis, and rotates with respect to the movement axis.

A cryogen injection apparatus for injecting a cryogenic substance into a blender, includes at least one nozzle constructed for being in fluid communication with an interior of the blender; and an electric heat sink member in contact with the at least one nozzle for electrically heating said nozzle. A related method is also provided.

A substrate processing apparatus includes a chamber that defines an internal space in which a plurality of types of chemicals are supplied to a substrate at different timings, an individual exhaust flow path that removes an atmosphere within the chamber through an exhaust inlet and an exhaust cleaning device that forms a dispersion region where a removal liquid, which removes a chemical contained in an atmosphere, is dispersed in at least one of a position on an upstream side of the exhaust inlet and a position within the individual exhaust flow path by discharging the removal liquid into air.
