A fluid container includes a tank, a magnetic ring, and an adaptor coupled to the tank via an o-ring seal. The magnetic ring includes two half-ring portions that, when assembled, form a full magnetic ring. The fluid container can be used to store DEF or other fluids. Assembling the fluid container includes positioning the magnetic ring within a groove formed in an outer surface of a conduit of the tank, and threading the adaptor onto the conduit to lock the magnetic ring in place.

An opening device for a urea water inlet may include a first body configured to be provided on an external side of an inlet of a urea filler neck; a second body disposed at an upper end portion of the first body with a ventilation gap between the first body and the second body, and provided with an internal space to be disposed above the inlet; a cover disposed at an upper end portion of the second body, and configured to receive a force to open the internal space of the second body; an opener provided in the second body, and configured to hold the cover at the upper portion of the second body when the cover is configured to close the internal space, and to release holding of the cover when being pressed toward an interior of the second body; and a membrane disposed between the first body and the second body to pass only air therethrough while covering the ventilation gap.

A thermal controlled hose assembly is provided and includes an adapter which defines an adapter cavity, wherein the adapter is configured to receive a DEF fluid within the adapter cavity, a hose, wherein the hose defines a hose cavity and wherein the hose is connected to the adapter such that the hose cavity is in flow communication with the adapter cavity, a nozzle, wherein the nozzle includes an inlet port and an outlet port and defines a fluid flow channel which communicates the inlet port with the outlet port, and wherein the nozzle is connected with the hose such that the fluid flow channel is in flow communication with the hose cavity and a heating system, wherein the heating system includes a heating element which is configured to be in contact with at least a portion of at least one of the adapter, the hose and the nozzle.

Disclosed is a liquid storage container which has an inspection window to check the completely filled state of the liquid storage container with a liquid injected thereinto and inhibit occurrence of a detection error of an optical concentration sensor due to light flowing into the liquid storage container through the inspection window. The liquid storage container includes a container main body configured to store the liquid, an inlet configured to inject the liquid into the container main body therethrough, the inspection window installed on the container main body and to confirm the completely filled state of the container main body with the liquid, a concentration sensor configured to detect the concentration of the liquid in the container main body, and a light blocking device installed in the container main body to block light entering through the inspection window.

The application relates to a pouch assembly (100) containing a liquid being an aqueous urea solution for use in a selective catalytic reduction system for treating the exhaust gases of an internal combustion engine of a vehicle and for transferring the liquid to a liquid tank of the vehicle from the outside of the liquid tank, the pouch assembly (100) comprising a flexible pouch (1) and a spout (2) attached thereto having a base (21) extending axially through an opening (111) provided in a wall of the pouch (1) and being attached to the opening (111), a top end (22) being configured for insertion in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, and a body (23) that extends between the base (21) and the top end (22) of the spout (2), the body (23) having an elongated shape, and the body (23) at least partially extending in the inside passage of the filling neck (3) of the liquid tank during the filling of the liquid tank, the base (21), the top end (22) and the body (23) having an elongated axial through-passage (211) to serve as a discharge passage for the liquid. The application relates furthermore to a system comprising such a pouch assembly (100) and a liquid tank having a filling neck (3) allowing insertion of the spout (2) for filling the liquid tank.

An automated diesel exhaust fluid (DEF) system and method for refilling DEF. The automated DEF system provides DEF refilling after an initial setup and without manual intervention. The automated DEF system includes a electric DEF flow control device that controls the flow of DEF. The electric DEF flow control device may include control circuitry, an electrics enclosure that encloses the control circuity, an electric fluid sensor, a valve, a beacon light, a status light, a button, a threaded swivel connection, and a mandrel on the inside of the threaded swivel connection.

Tank for a liquid solution based on water and urea which is suitable for being combined with a selective catalytic reduction system. The tank comprises: a container including an upper wall; a filling pipe union which is positioned on the upper wall of the container and which is suitable for introducing the liquid solution; a lower opening, from which the liquid solution being introduced passes into the container and which protrudes with respect to the upper wall towards the interior of the container; a closure float which is positioned in the container and which is connected to the lower opening and which is configured so as to raise and close the lower opening once the liquid solution in the container reaches a predetermined level.

A device for opening and closing a urea inlet for a vehicle is configured to close an inlet of a urea filler neck in a push manner and to open the same in a pull manner, preventing a user from touching the vehicle body or peripheral portions when opening and closing the inlet.

A fully-integrated flow-control module is designed to fit within a filler neck of a DEF tank that conforms to ISO (International Organization for Standardization) Standard 22241-4:2009(E). The flow-control module includes a breather cap that locks the flow-control module within the mouth of the ISO filler neck. A spring-biased valve piston, which is controlled by a bleed path within a bleed and float body, opens and closes to control fluid flow into the DEF tank. A fluid level float is mounted on a control rod. The control rod and a bleed valve poppet are rigidly secured to a connector beam. When fluid levels in the tank raise the float, the bleed valve poppet seals a bleed circuit escape port, thereby enabling the valve piston to close, increase fluid pressure at the nozzle, and cause the nozzle to shut off.
