A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). For example, the fluid exchanger may use a negative pressure, suction, or vacuum to draw the first fluid from the reservoir, and subsequently, the second fluid may be transferred into the reservoir using a negative pressure held in the reservoir, a positive pressure applied to the second fluid, or a combination thereof. The fluid exchanger may also include a multi-purpose, hand-held nozzle that can change an operation of the fluid exchanger from a withdrawing mode to a dispensing mode.

A system for high pressure processing of bulk, high viscosity flowable product includes a carrier having openings therein for receiving high pressure fluid into the carrier. A flexible product bag is disposed in the product carrier, the bag having a fitment for filling and emptying the bag with high viscosity, flowable product. An opening in the product carrier for access to the fitment. An emptying system cooperates with the carrier to act on the filled product bag to increase the pressure on the product in the product bag to assist in forcing the high viscosity product out of the product bag. A control system controls the operation of the emptying system.

A replaceable component for a beverage container to be attached to a beverage extraction pipe of the beverage container is provided. The replaceable component for a beverage container includes a tubular member slidable along a longitudinal direction of the beverage extraction pipe and capable of coming in annular contact with an outer circumferential surface of the beverage extraction pipe, and a bag, which is attached to the tubular member, for containing a beverage.

An improved fill cap for delivering a fluid from a fluid transporting mechanism to a fluid tank is disclosed. A connection plate is coupled to an opening of the fluid tank and a probe is disposed within the fluid tank and coupled to the connection plate at a first distal end. The fluid flows into the fluid tank through an outlet at a second distal end of the probe. A valve is disposed at the second distal end of the probe and is movable between an open position and a closed position to control fluid flow out of the probe outlet. An arm is coupled to the valve and moves the valve between the open and closed positions and a float is coupled to the arm that moves the arm depending on the level of fluid in the fluid tank.

Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.

A quantitative essential oil dripping device which includes: N sealed essential oil containers for containing essential oil, wherein N is a positive integer greater than or equal to 1; N gas inlet tubes and N oil outlet tubes, which are all inserted into the N essential oil containers respectively, wherein in each of the essential oil containers, a gas outlet of the gas inlet tube is located above an inlet of the oil outlet tube; a gas pump arranged at gas inlets of the N gas inlet tubes; a throttle valve communicating the gas pump with the essential oil container; and a drip number detection module configured to detect the drip number of the essential oil dripped from an oil outlet of the oil outlet tube. During use, the gas pump is started, pressure is applied to the essential oil container through the gas pump, and the essential oil is driven to be dripped from the oil outlet tube under the combined action of the gas pump and the throttle valve, thereby achieving the dripping of the essential oil. The drip number of the essential oil dripped from the oil outlet of the oil outlet tube is detected through the drip number detection module, and the amount of the dripped essential oil is measured by recording the drip number, thereby accurately controlling the dripping of the essential oil. After the dripping of the essential oil is completed, the gas pump is stopped.

Devices, systems and methods of transferring liquids or mixtures/slurries of liquids and solids between vessels having challenging and difficult configurations and locations, and over long and short distances in a continuous or near continuous discharge for storage or transport using a combination of vacuum and pressurized fluids.

A system for discharging a chemical from a drum that is coupled to a drum retainer is provided. The system includes a booth having a floor, a ceiling, and walls defining an enclosure therein and configured to enclose the drum and the drum retainer. A first gas source is coupled to the booth and in flow communication to the enclosure and configured to discharge a first inert gas into the enclosure. A second gas source is coupled in flow communication to the drum and configured to discharge a second inert gas into the drum and to pressurize the chemical. The system further includes a pump coupled in flow communication to the drum and configured to discharge the chemical from the drum under at least one predetermined characteristic and out of the enclosure.

A water supply system includes a water storage tank having a storage tank outlet, the water storage tank configured to store a volume of water at a first pressure. A pressure tank is in fluid communication with the water storage tank and is periodically fillable with water from the water storage tank. An air source is fluidly connected to the pressure tank to pressurize the volume of water in the pressure tank to a second pressure greater than the first pressure. A pressure tank output line is fluidly connected to the pressure tank to output water from the pressure tank.
