A fill valve for receiving a fluid flow includes a lower pipe and a flow restrictor cartridge. The flow restrictor cartridge is received in the lower pipe. The flow restrictor cartridge receives the fluid flow at a first fluid flow rate and provides the fluid flow as a second fluid flow rate lower than the first fluid flow rate. The flow restrictor cartridge includes a receiver and a compact flow restrictor. The compact flow restrictor is received by the receiver. The compact flow restrictor is configured to facilitate the reduction from the first fluid flow rate to the second fluid flow rate.

Method and apparatus for air flow regulation comprise a vertically oriented tube, a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to regulate rate of air flow through the tube and to stop air flow through the tube upon air flow rate through the tube exceeding a preselected value with a detector for sensing when the sail assembly has stopped air flow thought the tube as a result of air flow rate exceeding said pre-selected value.

Some embodiments include a flow regulator with a main body dimensioned to be received within a flow passageway that includes an inlet and an adjustable outlet. Further, some embodiments include an inner chamber positioned in the main body extending from at least proximate the inlet of the main body along at least a partial length of the main body and positioned as an upstream section. Some embodiments include a compressible or expandable extending vane extending from the main body and extending around the inner chamber. Some further embodiments include an adjustable fluid flow space extending around or over at least a portion of the extended vane that is configured to receive at least some fluid from at least a portion of the flow passageway, where the fluid comprises a fluid flow rate and a fluid pressure.

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

A flow rate control device includes a needle valve mounted within a body section and is configured such that the needle valve is advanced and retracted within the body section by the rotation of a handle, thereby adjusting the flow rate of fluid flowing between a first port and a second port. The handle is surrounded by a cover to prevent a change in the adjusted flow rate.

Method and apparatus for air flow regulation comprise a vertically oriented tube, a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to regulate rate of air flow through the tube and to stop air flow through the tube upon air flow rate through the tube exceeding a preselected value with a detector for sensing when the sail assembly has stopped air flow thought the tube as a result of air flow rate exceeding said pre-selected value.

Method and apparatus for air flow limiting comprise a vertically oriented tube, a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to limit rate of air flow through the tube and halt air flow through the tube upon air flow rate through the tube exceeding a preselected value, and a moveable stop for adjustably changing the length of travel of the sail assembly thereby changing the maximum amount of air flow.

An oscillating flow controller includes a housing, a first valve operable between first and second positions, a second valve operable between first and second positions, and a biasing mechanism configured to simultaneously bias both the first and second valves toward their respective first positions or second positions. The housing, the first valve, and the second valve cooperate to define a first pilot chamber and a second pilot chamber. When the first and second valves are in their respective first positions, they disable fluid flow into the first pilot chamber and out of the second pilot chamber, while enabling fluid flow out of the first pilot chamber and into the second pilot chamber. When the first and second valves are in their respective second positions, they enable fluid flow into the first pilot chamber and out of the second pilot chamber, while disabling fluid flow out of the first pilot chamber and into the second pilot chamber. The first and second valves change state in response to supply of pressurized fluid to the first and second pilot chambers through the first valve.
