摘要： The system includes a fluid valve with a modular and/or replaceable fluid control assembly that requires maintenance over a product life of the fluid valve. The modular and/or replaceable fluid control assembly includes at least one portion including a setting or presetting configured and arranged to control fluid flow behavior in the fluid valve. The setting or presetting is useable to control fluid flow in the modular and/or replaceable fluid control assembly after an upgrade or replacement of at least a portion of the modular and/or replaceable fluid control assembly. Further, the setting or presetting enables the modular and/or replaceable fluid control assembly to retain the fluid flow behavior following one or more upgrades or replacements of one or more portions of the modular and/or replaceable fluid control assembly.

摘要： The disclosure is directed to an exchangeable fill valve system. In some embodiments, the system includes an interchangeable shank that enables attachment of different fill valve types. In some embodiments, the interchangeable shank enables different fill valve types to be removed from a fluid tank without also removing the interchangeable shank from the tank wall. In some embodiments, the interchangeable shank also houses an inline filter, where the filter can be accessed by disconnecting the fill valve. In some embodiments, the exchangeable fill valve system includes floats that capture fill water drives the floats down actuating a fill valve lever. In some embodiments, the floats include one or more holes that enable a timed discharge of the fill water from the floats.

摘要： Some embodiments include a flow regulator with a main body dimensioned to be received within a flow passageway that includes an inlet and an outer surface, and an inner volume positioned within the main body and extending from the inlet along at least a partial length of the main body. Some embodiments includes two separate spiral structures positioned spiraled around the main body where one spiral extends further from the outer surface than the other. Some embodiments include a fluid flow space extending between the spirals. Based on a fluid pressure, the spirals can expand and contract to control the fluid flow space and affect downstream, fluid flow rate as a function of upstream fluid pressure.

摘要： Some embodiments include a valve assembly with a metering seal including a main channel including regions with a first diameter and regions with a second diameter, where the first diameter is smaller than the second diameter. Some embodiments include a stem positioned in the metering seal extending from at least a first end of the metering seal to a second end of the metering seal. In some embodiments, the stem has a fluted section positioned between two non-fluted sections, where the diameter of stem in the fluted section is smaller than the diameter of the stem in the non-fluted sections. Some embodiments include a first and second flow channel extending across at least a partial width of the metering seal, where the first flow channel is positioned at the first end of the metering seal, and the second flow channel is positioned at the second end of the metering seal.

摘要： Some embodiments include a fluid control system with an outlet valve assembly, an inlet valve assembly including a venturi inlet valve, and an actuator coupled to the inlet valve assembly. In some embodiments, the actuator can enable a user to control a flush volume of fluid control system. Some embodiments include a moveable float positioned in a chamber of the outlet valve assembly, where the chamber includes a variably-sized upper portion with a volume that is based at least in part on a variable position of the moveable float in the chamber. Some embodiments include a adjustable control valves coupled to an outer surface of the outlet valve assembly and the inlet valve assembly. Some embodiments also include a bellows positioned in and coupled to the variably-sized upper portion. In some embodiments, the bellows are fluidly coupled to the venturi inlet valve and at least one of the control valves.

摘要： An improved flush system as described herein may comprise a reservoir with a drain opening for egress of liquids disposed in the reservoir into a surrounding toilet tank. A lock mechanism is slidably received by the reservoir so that the lock mechanism is translatable between one or more fixed positions on the reservoir. In turn, translating the lock mechanism into the reservoir at increasing depths causes a size of the drain opening to be reduced and therefore adjusted.
