To provide a spout apparatus which is easily maintainable by a user even when, in a fluid device utilizing Karman vortices, scale adheres to the Karman vortex generating portion. A spout apparatus for discharging hot or cold water while causing it to reciprocally oscillate, having a spout apparatus body and an oscillating element; whereby the oscillating element has a water supply passage, a vortex generating passage, and a spout port passage; the spout port passage is formed of an elastically deformable soft member and is attached to the spout apparatus body so that a user can manipulate the spout port passage to deform it; and the vortex generating passage is formed of an elastically deformable soft member, and is integrally formed with the spout port passage so that deformations of the spout port passage can be transmitted to this vortex generating passage.

A nozzle device for sorting objects by ejecting a gaseous media towards said object. The nozzle device nozzle device including: a nozzle unit including at least one nozzle; a nozzle bar including gas supply means for providing a gaseous media to said nozzle unit; and a nozzle fixation bracket adapted for holding said nozzle unit in place; said at least one nozzle including: an inlet for receiving the gaseous media; and having one outlet, having an outlet area, for ejecting the gaseous media towards an object to be sorted; a channel extending between said inlet and said outlet; an outlet portion surrounding at least said outlet, wherein said outlet portion including a flexible material, which deflects upon ejection of the gaseous media, received from said nozzle bar, through said outlet whereby said outlet area increases. Also, a system for sorting objects.

A nozzle apparatus includes a manifold defining a nozzle cavity within an interior, a fluid inlet passage, a fluid outlet passage, an air outlet passage, and an air inlet passage. A nozzle holder and a nozzle element are selectively pivotable within the nozzle cavity. In the nominal position, the nozzle element inlet is oriented toward the fluid passage inlet and the nozzle element outlet is oriented toward the fluid passage outlet such that the primary fluid flows through the fluid inlet passage and out of the nozzle outlet through the fluid outlet passage. In the cleaning position, the nozzle element inlet is oriented toward the air outlet passage and the nozzle element outlet is oriented toward the air inlet passage such that the flow of air is directed through the air inlet passage, and out of the air outlet passage to direct debris out through the air outlet passage.

To provide a spout apparatus whereby expansion and deformation of the inner wall surface of the vortex generating portion such that a desired Karman vortex cannot be generated are prevented, even when the port portion is formed of an elastically deformable soft member. A spout apparatus for discharging hot or cold water with reciprocal motion, having a spout apparatus body and a vortex generating passage; whereby the oscillating element has a supply passage, a vortex generating passage, and a spout port passage, and the spout port passage is formed by an elastically deformable soft member, and is attached to the spout apparatus body so that a user can manipulate and deform the spout port passage, and the vortex generating passage is formed so as not to expand and deform even if internal pressure rises due to the supply of hot or cold water from the supply passage.

An improved dispensing device for application and dispensing of viscous liquid substances comprising of a storage reservoir, dosing mechanism with audible and tactile feedback, dispensing plunger, nozzle tip, and end of travel pressure release mechanism. The dosing and the dispensing are de-coupled, allowing a preselection of dosage volume and controlled dispensing. A pressure relief mechanism is incorporated to eliminate oozing of liquids after the termination of dispensing.

A shower jet outlet device and a shower head equipped therewith have a jet disk with at least one jet disk opening and a jet outlet element disposed in the jet disk opening. The jet outlet element is pot-shaped with an outlet-side bottom, a side wall and a hollow chamber delimited by the bottom and the side wall. The bottom faces in the jet outlet direction and includes fine jet openings. The bottom and the side wall are made of an elastic material and the jet outlet element is configured to deform by bulging of its bottom and/or its side wall, in response to fluid pressure in the hollow chamber when operating.

A shower jet generating device for a sanitary shower head has a jet disk that delimits a fluid chamber on the outlet side and has at least one jet disk opening. A fluid outlet element is disposed on the at least one jet disk opening and is movable in an axial main direction component, which element includes a movable valve body having a fluid outlet opening issuing from the fluid chamber. The fluid outlet opening is unblocked in an unblocking position of the fluid outlet element and is blocked in a blocking position of the fluid outlet element in response to a fluid pressure in the fluid chamber. The movable valve body cooperates with an unmovable valve seat which unblocks the fluid outlet opening in the unblocking position of the fluid outlet element and blocks it in a blocking position of the fluid outlet element.

A flotation machine includes a wash water system that is connectable adjacent a tank to direct sprays of water into froth within a froth zone. Wash water panel assemblies of the system can be positioned adjacent the tank so that each of the wash water panel assemblies are moveable between an open position and a closed position. Each wash water panel assembly can include an outer panel body that at least partially defines a reservoir in which wash water is passable and a spray membrane positionable adjacent the outer panel body. The spray membrane can have a plurality of spray holes in fluid communication with the reservoir such that water is passable from the reservoir and through the spray membrane via the spray holes for spraying water into the froth in the froth zone.
