An aerator including a faceplate for dispensing a first water stream, and a nozzle for dispensing a second water stream, the second water stream surrounded by the first water stream.

A water delivery system includes a mixing valve operable for delivering a water flow of adjustable temperature from a water source to a dispensing device downstream from the mixing valve; a thermochromic thermal indicator, fluidly coupled between the mixing valve and the dispensing device, that provides a visible indication of the water flow having achieved a predetermined temperature; and a diverter valve, fluidly coupled between the mixing valve and the dispensing device, and operable to direct the water flow selectively either to the dispensing device or back to the water source. The thermal indicator may be a thermochromic PVC conduit, or it may be a fitting having an inlet, an outlet, a thermochromic PVC element therebetween, and a barrier located between the inlet and the outlet so as to define a flow path that includes an interior surface of the thermochromic element.

A fuel injector includes an injector body comprising an internal injector cavity, a flow passageway, and a drain conduit. The flow passageway is in fluid communication with at least one injector orifice. The fuel injector further includes a valve assembly comprising a valve seat and a valve member in fluid communication with the fuel circuit. The valve member is configured to move between an open position allowing fuel flow through the at least one injector orifice and a closed position inhibiting fuel flow through the at least one injector orifice. The fuel injector also includes a nozzle valve element fluidly coupled to the valve assembly, an actuator operably coupled to the valve assembly and the nozzle valve element, and a flexible member configured to elastically deform in response to pressure in the fuel injector. The flexible member is configured to inhibit flow to the drain circuit during an injection event.

A combined shower with a gravity switch mechanism includes a wall-fixed shower, a handheld shower and a water diversion component, the water diversion component includes a water inlet, two water outlets respectively connected to the wall-fixed shower and handheld shower, and a switching component which is used to switch the waterway communication between the water inlet and two water outlets. The shower also includes a gravity switch mechanism and an attachment portion. The attachment portion interacts with the switching component to drive the activation of the switching component to trigger the switch to make the handheld shower activate or remain static relative to the position of the wall-fixed shower.

System and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes a flow control routine in which the velocity of an applicator, or other parameter affecting the amount of material applied to the substrate, is iteratively adjusted. The amount of the adjustment performed in each iteration is tracked. When the sum of the adjustments by the flow control routine exceeds a predetermined threshold, a fan width control routine is initiated in which the fan width of the stream of material applied by the applicator is adjusted.

A fluid injector for injecting fluid is disclosed, including a body; a fluid passageway defined in the body and extending from an inlet to an outlet of the fluid injector; a valve seat disposed internally of the body and forming part of the passageway; a valve element that is selectively reciprocated relative to the valve seat to close and open the passageway to fluid flow by seating and unseating the valve element on and from the valve seat, respectively; and an orifice disc disposed in the passageway downstream of the valve seat in a direction of the fluid flow through the fluid injector, the orifice disc including a plurality of dimples and a plurality of orifices defined through the orifice disc, each dimple including at least one orifice located thereon and each dimple having an asymmetrical cross-section.

A water jet condenser with multiple closed water chambers and a jet flow adjusting valve used in a sugar refinery. A water chamber of the condenser is divided into an open large water chamber (6) and a plurality of closed small water chambers (14); each water chamber is respectively provided with a jet nozzle (3) and a spray nozzle (7); the plurality of closed small water chambers (14) are respectively controlled by a plurality of pneumatic or electric butterfly valves (4); the lower part of the condenser body (13) is provided with a single-layer or multi-layer jet flow regulating valve (2) for keeping the concentric change of the diameter of the central round aperture of a jet flow passage; the jet nozzle (3) and the spray nozzle (7) in each water chamber are respectively cooperated with the single-layer or multi-layer jet flow regulating valve (2).

A sprinkler includes a body defining (a) a passage having an inlet and extending along a longitudinal axis and (b) an outlet fluidly coupled to the passage. The sprinkler includes a seal engaging a button and the body to fluidly seal the inlet from the outlet. A link and lever assembly includes a first lever and a second lever engaging the button. The first lever and the second lever each include (a) a leg positioned near a base end of the lever and extending outward from the longitudinal axis, the leg defining an engagement surface, (b) a head positioned near a tip end of the lever, and (c) a main body extending from the leg to the head. A fusible link limits movement of the heads. The engagement surfaces each engage a surface of the body to limit movement of the button along the longitudinal axis.
