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.

A nozzle for use in dispensing a fluid, such as water or a foaming agent to extinguish a fire, comprises a longitudinal body that comprises a plurality of helical shaped cam paths. The cam paths allow the operator of the nozzle to adjust a flow setting for the nozzle by moving a flow adjustment mechanism that is operatively associated with the cam paths.

The disclosure relates to a coating agent valve (1) for controlling a flow of fluid of a coating agent mixture consisting of two coating agent components (H, SL), in particular a two-component paint consisting of a master batch (SL) and a hardener (H). The coating agent valve according to the disclosure (1) comprises a valve seat, a displaceable valve head (12), a valve drive (15) for displacing the valve head (12) and a displaceable valve needle (14, 20) which connects the valve drive (15) to the valve head (12) and moves the valve head (12) in correspondence with the valve drive (15). The disclosure provides for an automatic reduction in pressure in order to avoid excess-pressure damage upstream from the coating agent valve (1).

A recirculating fluid flow system for an appliance includes a fluid pump that delivers process fluid through a fluid path. A tub is disposed within a cabinet and defines a processing space. The fluid path includes at least a portion of the processing space. The tub has an outlet that directs the process fluid toward the fluid pump. A sprayer assembly is coupled with the tub for directing the process fluid into the processing space. The sprayer assembly includes a spray head having a plurality of spray nozzles and an operable seam that extends through each spray nozzle of the plurality of spray nozzles. The operable seam is selectively separable to define a release opening that includes at least two spray nozzles of the plurality of spray nozzles.

In a water processing system in which a buildup in the components is experienced, an abrasive can be injected into the system to move the liquid/abrasive mixture therethrough to remove the residue and other material that has build up on the inside surfaces of the components. The liquid/abrasive mixture can be pumped with a high pressure, and with an elevated temperature, to facilitate removal of the residue.

A self-cleaning water nozzle uses specially configured nozzle halves to allow for self-cleaning, easy access to the nozzle components, and forming a hollow cone spray. The nozzle halves have grooves in side faces thereof, which when the nozzle halves are mated, the grooves form a spiral path for water to travel through the nozzle halves and form the hollow cone spray.

A spray nozzle for a steam generator of a shower steam system includes a housing defining a longitudinal bore extending to an outlet, and an atomizing member positioned adjacent the outlet. An elongated member is coupled to the housing in the longitudinal bore, and defines a pin at an end thereof. A body is slidably coupled to the housing in the longitudinal bore, and includes an opening extending therethrough. A biasing member is configured to bias the body against the elongated member by a biasing force such that the elongated member extends through the opening. The body is configured to move axially away from the elongated member toward the atomizing member in response to a pressure of a flow of water being above a threshold value so as to overcome the biasing force and allow the flow of water to pass through the opening to the atomizing member.
