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.

The present invention provides a filling nozzle obtained by using a resin selected from a cycloolefin polymer and a cycloolefin copolymer, or a filling nozzle including a tubular passage for supplying a pharmaceutical solution, and a filling port disposed at a lower end of the tubular passage, in which the tubular passage and the filling port have a circular peripheral cross-section, and an inner diameter of the passage of the filling port is larger than an inner diameter of the tubular passage disposed on an upstream side.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.

A nozzle monitoring system is provided for a sprayer system of a work vehicle. The system includes a first sensor configured to generate signals associated with vibrations of a first nozzle apparatus on the work vehicle that disperses a primary fluid from the sprayer system during operation; and a controller having a processor receiving the signals generated by the first sensor and having a memory coupled to the processor and storing instructions. The processor executes the stored instructions to: convert the vibrations into a frequency domain representation; generate an image from the frequency domain representation; classify the image to generate a clog condition probability; and generate, based on the clog condition probability, a command to initiate a cleaning event of the first nozzle apparatus.

A nozzle apparatus is configured to distribute a primary fluid. The nozzle apparatus includes a support plate; a fluid manifold; a fluid nozzle element; an actuator gear assembly; and a pincher gear assembly having a first pincher gear and a second pincher gear mounted on the support plate. The actuator gear assembly is configured to drive the pincher gear assembly between a first position in which the first and second pinchers are positioned relative to each other and relative to the fluid nozzle element such that the fluid nozzle element has a first cross-sectional shape and a second position in which the first and second pinchers are positioned relative to each other and relative to the fluid nozzle element such that the fluid nozzle element has a second cross-sectional shape. The first cross-sectional shape is different than the second cross-sectional shape.

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.
