A fluid storage and dispensing system that safely and efficiently stores all grades of motor oil is provided. The system is configured to accurately dispense motor oil into vehicles. The system may also be used for the storage of and dispensing of other fluids.

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.

An environmentally friendly multifuel fueling platform includes a tower structure and a canopy structure supported on legs a predetermined distance above ground to facilitate the passage of land vehicles beneath. The canopy structure is releasably affixed to the tower structure. An energy source is housed within the canopy structure and the tower provides access to the canopy from the ground, as well as providing operational supply of one of a liquid, gaseous and electrical energies to the energy source.

A fluid product reservoir, for a dispensing system, is made of a container having walls that include an aperture formed at one end thereof. A reservoir cap seals the aperture from exposure to the atmosphere. A pump integrated into the reservoir cap allows fluid product to be dispensed from the dispensing system. A closed venting mechanism is included and incorporates one or more air channels that direct ambient air into a bladder positioned internal to the fluid product reservoir. The expansion of the bladder functions to displace fluid pumped from the reservoir thereby equalizing pressure while maintaining a sanitary seal of the fluid reservoir.

A pneumatic drum emptying station locates a lance over an opening in a container. A lance can be inserted into the container to remove material from the container. Pneumatic cylinders may lock a carriage supplying the lance at a desired position along an arm. The arm, rotatable relative to a base post, may be locked in a specific position with pneumatics. Supports may assist in reloading/repositioning containers relative to the base.

A beverage dispensing apparatus is adapted to mix together a concentrate fluid with a base fluid. In certain implementations, the apparatus includes a cool fluid trunk line carrying the base fluid, a manifold, an in line and an out line extending between the cool fluid trunk and the manifold, a python and a bar gun assembly fluidly connected to the downstream side of the manifold by a plurality of conduits contained in the python, the apparatus including a recirculation channel having an inlet port and an outlet port, wherein the inlet and outlet ports of the recirculation channel are fluidly connected to respective in and out conduits in the python, the said in and out conduits being fluidly connected respectively to the in line and the out line of the cool fluid trunk line via the manifold. The beverage dispensing apparatus may further include a plurality of product lines, a mixing device, and a dispensing outlet, wherein at least one of the product lines is fluidly connected to a source of concentrate and at least one of the product lines is fluidly connected to a source of base fluid.

A fuel vapor recovery control system includes a controller, a recovery electrical motor, a fuel vapor switching valve, a fuel vapor recovery pump, a fuel tank, a fueling pump, a fuel gun, and a temperature sensor connected in sequence. A fueling flowmeter is arranged on a fueling pipeline, in signal connection with the controller, the recovery electrical motor and the fuel vapor recovery pump in sequence. The temperature sensor is in signal connection with the controller for controling the recovery electrical motor and the fuel vapor recovery pump by temperature signals. The fuel vapor recovery control system includes a fuel vapor flowmeter for measuring the fuel vapor recovery amount, in signal connection with the controller for controling the recovery electrical motor and the fuel vapor recovery pump by fuel vapor recovery amount signals. The fuel vapor recovery ratio is between 1-1.4. A method of adopting the system is provided herein.
