A spraying device includes a spray head, which is connected to a supply line, via which a pressurized fluid can be conveyed. The spraying device includes a metering screw for influencing the fluid jet passing out of the spray head. The spraying device is designed such that a pointer element having at least one marking is connected to the metering screw in a rotationally fixed, yet detachable manner.

An injection valve including a valve body defining an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet. A valve shaft is disposed in the valve body, and a valve plug is operatively connected to the valve shaft. The valve plug is movable between an open position, in which the valve plug permits fluid flow between the inlet and the outlet, and a closed position, in which the valve plug limits flow between the inlet and the outlet. A seat ring defines a valve seat and is proximally disposed relative to the outlet of the valve body. The valve plug moves away from the valve seat when moving in a direction toward the valve body, and toward the valve seat when moving in a direction away from the valve body.

In an electrostatic atomization coating apparatus including a nozzle head including a plurality of coating material ejection ports; a coating material chamber that is provided inside the nozzle head and to which a coating material is supplied via a coating material supply path, each of the coating material ejection ports being in communication with the coating material chamber via an individual branch coating material path; and a voltage application device that provides a potential difference between the nozzle head and an object to be coated, the coating material ejected from each of the coating material ejection ports via the coating material supply path, the coating material chamber, and the branch coating material path being brought into a charged state through application of a voltage by the voltage application device, an open/close valve device that opens and closes all of the branch coating material paths, or opens and closes a specific subset of a plurality of branch coating material paths out of all of the branch coating material paths is provided. Thus, it is possible to prevent external air from entering the nozzle head, and the coating material from leaking to the outside of the nozzle head.

Embodiments of the present disclosure provide for coaxial nozzles, capsule fabrication systems comprising coaxial nozzles, and methods of capsule fabrication using capsule fabrication systems. In certain embodiments, coaxial nozzle configurations, capsule fabrication systems, and methods as described herein can be used for multi-layered capsule fabrication.

The present disclosure discloses a waterway switching mechanism comprising a mounting portion, a water dividing plate, and a driving mechanism. The mounting portion comprises at least one water dividing passage, and the water dividing plate cooperates with the at least one water dividing passage to switch a waterway through rotation of the water dividing plate. A third upper guiding surface of the movable block contacts and couples to a first inner guiding surface of the water dividing plate to enable the movable block to move to drive the water dividing plate to rotate in a first direction. The movable block cooperates with a fixing guiding surface of an upper matching portion of the mounting portion to enable the push rod to move to drive the movable block and the water dividing plate to rotate in the first direction.

A shower with an adjustable water spray comprises a body portion and an adjusting member. The body portion comprises a water inlet passage and a plurality of water outlet nozzles. The adjusting member comprises a plurality of adjusting portions, and an outer side of each of plurality of adjusting portions comprises a plurality of adjusting grooves extending longitudinally. A size of each of the plurality of adjusting grooves gradually reduces in a downward direction. An inner wall of each of the plurality of water outlet nozzles comprises a sealing portion, and each of plurality of adjusting portion extends into a corresponding one of the plurality of water outlet nozzles and hermetically and movably cooperates with a corresponding one of the sealing portions. The plurality of adjusting grooves of each of the plurality of adjusting portions and a corresponding one of the sealing portions defines an adjustable water outlet hole.
