An automatic obstruction device for closing a filling circuit for filling a tank with fluid includes: a movable element movable between a non-obstruction position of the filling circuit, in which the movable element offers resistance to the fluid compatible with the filling of the tank, and an obstruction position of the filling circuit, in which the movable offers a resistance to the fluid that is incompatible with the filling of the tank; a holding element of the movable element holding the movable element in the non-obstruction position, and allowing movement of the movable element toward the obstruction position; and a first device of non-reversible movement or of non-reversible modification of the holding element allowing movement of the movable element toward the obstruction position, and being controllable by a control device.

Disclosed herein are embodiments of liquid dispensing container preferably configured as portable, handheld liquid dispensing containers. These liquid dispensing containers possesses a vent structure that provides improved liquid dispensing along with simplified vent construction and container integration. In these regards, these liquid dispensing containers advantageously overcome one or more shortcomings associated conventional liquid dispensing containers and other types of containers.

A refueling vehicle may have a front fuel dispensing module with at least one or more hoses for dispensing fuel product from the fuel tank to an external tank. The front fuel dispensing module is located between the cab and the fuel tank containing the fuel product.

A filler neck adaptor for use with manually operated fuel dispensing nozzles. Adaptor provides a visual cue that a target fuel level in the tank has been reached during tank filling operations. Adaptor comprises a flanged extension tube with an overflow reservoir sealed to the upper surface of the flange. A slidably adjustable securement ring is mounted on the extension tube. The securement ring is designed to mate with tank closure features on the filler neck. An airlock tank seal is installed on the lower surface of the securement ring to establish a seal between the securement ring and the tank filler neck. During filling displaced air in the tank is forced to exit the tank via an air vent passageway between the nozzle and the inside surface of the adaptor extension tube. As the rising fuel level in tank nears the distal end of the extension tube, wisps of fuel becomes entrapped in the airstream and become visible in the transparent overflow reservoir. This visual cue that the tank is full allows the operator to stop fuel flow prior to overflow spillage.

An example fluid container fill indicator system generates an alert in response to a change in pressure at the exhaust conduit or the fluid container. In some example, the change in pressure causes a reed or whistle type device to generate an audible alert. In some examples, the alert is a mechanical and/or electronic signal based on a change in position or orientation of a valve in response to the change in pressure.

A filling valve for filling a container with a filling product, e.g., a beverage in a beverage filling system, includes a valve base body. The valve base body includes an outlet configured to discharge the filling product into the container; a swirl chamber configured to receive the filling product and is able to be brought into a fluidic connection with the outlet; and a main inlet, which feeds into the swirl chamber and is configured to introduce at least one main component of the filling product into the swirl chamber such that the filling product is swirled in the swirl chamber, whereby after exiting from the outlet the filling product flows downwardly in a spiral movement in the container. The swirl chamber has an annular shape, the cross-sectional contour thereof having a rounded shape, substantially without corner points, in the direction of extent and perpendicular to the direction of extent.

The invention relates to a fuel dispenser (1) comprising a hose storage space (2) adapted to accommodate at least one fuel hose (3), an electronic compartment (4) containing a main frame control unit (5), and a hydraulic compartment (6) containing fuel dispensing means (22) for dispensing fuel into a vehicle reservoir. According to the invention, the hydraulic control unit (7) is located inside the hydraulic compartment (6) and is electrically connected to the mainframe control unit (5) by a main electric cable means (17). The invention also relates to a method for handling a fuel dispenser (1).

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

Multiply redundant safety system(s) that protects humans and assets while fueling vehicles, and/or transferring/fueling/tank exchanging of on road/off road, marine, aircraft, spacecraft, rockets, and all other vehicles/vessels utilizing Compressed and/or Liquefied Gas Fuels/compound(s), utilizing Hydrogen and/or Natural Gas Chemical Family of Natural Gas/Propane/Butane/ethane/ammonia/and/or any/all compound(s)/mixtures along with and/or without, oxidizer(s), such as Liquefied Oxygen, Oxygen Triplet (O3)/ozone/hydrogen peroxide/peroxide/solid oxidizer(s). One or more processors in combination with one or more system(s)/one or more sensor(s); in combination with one or more micro switches/one or more outputs/actuator(s) which combine to detect any leaks/fire(s)/explosion/voltage(s)/hazards/vehicle position/motion/vessel motion(s)/reusable tank/exchange tank/position(s)/arc's, spark(s)/and/or other hazards for rapid mitigation by locking out/stopping fueling/gas transfers/vehicle releasing/transfer line releasing. For different levels of safety, multiple combination(s) of various sensor(s)/detector(s)/input(s)/output(s)/device(s)/system(s)/action(s)/actuators, all may be standing alone and/or in any combination can be utilized.
