A device equipped with a tank, includes: the tank to be filled with a fuel gas; a valve mechanism provided in the tank; a receptacle with which a nozzle of a fuel gas filling device is connectable; a first filling path, an upstream end of the first filling path communicating with the receptacle; a second filling path, a downstream end of the second filling path communicating with the tank through the valve mechanism; and a storage container hermetically communicating between a downstream end of the first filling path and an upstream end of the second filling path, and storing foreign matter contained in the fuel gas, wherein the storage container is positioned vertically above the downstream end of the first filling path.

A refueling system includes a first fuel source, a second fuel source, and a fuel source selection device. The fuel source selection device includes a fuel mixer comprising a mixing chamber, a first inlet in fluid communication with the mixing chamber and configured to be fluidly coupled to an engine, a second inlet in fluid communication with the first fuel source and the mixing chamber, a third inlet fluidly coupled to the second fuel source, a first outlet in fluid communication with the engine and the mixing chamber, and a second outlet fluidly coupled to the second fuel source. The fuel mixer is configured to operate in a first mode or a second mode. In the first mode, fuel passes from the first fuel source to the engine. In the second mode, fuel passes from the second fuel source to the engine.

A handling system for a filling system for filling containers and circuits of vehicles with different operating materials on assembly lines of the automobile industry is disclosed. The filling system has a base unit, a controller, a console, and an adapter. The adapter is operatively connected to a hose packet for supplying the respective operating materials which is movably supported on the console. The handling system handles the hose packets which are operated with a medium other than a pneumatic system. The drive of the movable hose packets and the drive system of a lifting unit equipped with a tray for the adapter are each designed as an electromotive drive. The disclosure further provides the sequences of movement of the adapter and lifting unit.

A system and method for fueling multiple saddle tanks of hydraulic fracturing equipment from a single self-propelled cart. The cart having multiple retractable fuel lines for providing and obtaining fuel. Each retractable fuel supply line uses a flowmeter, a ball valve, and an electrically actuated valve to provide remote control to a controller based on a user's selected fueling requirements. An electronic reporting system provides fuel data to operators and users. Fuel data such as fuel tank status, an amount of fuel usage over a stage level, a daily level, or job level along with a fill level of the fuel tank.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

The present invention encompasses a system and method for automatically replacing vehicle fluid, such as engine oil, with a robotic serving unit or robotic machine. The robotic machine comprises a motorized, autonomously maneuverable unit that has on its top a drainage arm to connect with an oil drain plug of a vehicle. In a preferred embodiment, the oil drain plug comprises a hollow interior for the drainage arm to connect with and drain the oil, and can also comprise a sealable element to retain the oil.

System and method relates to a fuel control and distribution system comprising a fuel source, a fuel line, wherein the fuel source is connected to the fuel line, a fuel pump, wherein the fuel line is connected to the fuel pump, a main fuel line, wherein the fuel pump is connected to the main fuel line, a first remote transport truck, wherein the first remote transport truck comprises a first remote transport truck fuel line, wherein the main fuel line is connected to the first remote transport truck and wherein the first remote transport truck fuel line is connected to the first remote transport truck, a first tap line, wherein the first remote transport truck is connected to the first tap line, and a first fuel cap, wherein the first fuel cap comprises a first fuel level sensor, wherein the first tap line is connected to the first fuel cap and wherein the first fuel cap is adapted to be removably attached to a first equipment fuel tank.

A device for automatic refueling of a vehicle. The device includes a nozzle including a connecting means and a flexible filler pipe with an open end. The filler pipe is configured to be inserted via an axial pressure applied to the filler pipe at a location spaced from the open end, with the open end first, into the tank pipe to deliver fuel through the open end into the tank pipe. The filler pipe includes an inner fuel pipe of flexible hard plastic material, and an outer metal coil or a series of metal rings. The metal coil or metal rings are arranged to run in parallel to and outside of the inner fuel pipe, and the metal coil or metal rings are arranged to run in and along a recess in the surface of the inner fuel pipe.

Systems and methods for mobile refueling by mobile fuel carriers of vehicles of approved users at approved mobile refueling locations. The system may include a server connected to a network and a database accessible by the server that includes approved refueling location information and approved user and user vehicle information, including vehicle identification fuel preference information. User computers communicate with the server via the network, the user computers sending refueling request information including user identification and vehicle location information to the server. The server sends refueling instructions to a fuel carrier computer having a user interface which allows updating of route information with real-time information pertaining to user requests and fuel carrier location data.
