An anti-siphon device and method for operation of an anti-siphon device is provided. The anti-siphon device includes a plurality of radially aligned fins that are unsupported at one end and attached to a carrier body at a second end.

A method is used to control a fuel level gauge of a vehicle system and includes: monitoring, via an engine controller, a fuel economy of the vehicle system; comparing, via the engine controller, the fuel economy with a predetermined fuel economy threshold to determine whether the fuel economy is less than the predetermined fuel economy threshold; adjusting, via the engine controller, a sensitivity of a display filter in response to determining that the fuel economy is less than the predetermined fuel economy threshold for a predetermined amount of time in order to maximize an accuracy of the fuel level gauge, wherein the display filter smoothes an unfiltered fuel level signal received from a fuel level sensor of the vehicle system, thereby generating a filtered fuel level signal; and controlling, via an instrument panel controller, the fuel level gauge of the vehicle system.

A closure device for a fluid container, in particular a hydraulic tank, has a base (4), which can be attached to the container opening and has a cover part (2), which encloses a ventilation and/or a filter device (36). The cover part (2) is held on the base (4) so as to be freely rotatable in a functional unlocking position. In a functional locking position, the closure device permits the container opening to be unlocked by a safety device (48, 50, 58) while connecting the cover part (2) to the base (4). The safety device (48, 50, 58) can be actuated by a magnetic device generating a magnetic field (62). The magnetic device establishes the functional locking position of the cover (2) and the base (4) by magnetic force.

A locking system for a fuel compartment assembly of a work vehicle, the locking system having a housing at least partially defining a fuel access compartment, a door pivotally coupled to the housing and movable between an opened position, at which the door provides access to the fuel access compartment, and a closed position, at which the door blocks access to the fuel access compartment, and a locking assembly configured to lock the door at the closed position. The locking assembly includes a catch fixed to the housing and positioned within the fuel access compartment, and a latch arm pivotably coupled to the door at a pivot point defined between first and second ends of the latch arm, the pivot point defining a first pivot axis, where the latch arm is configured to be pivoted about the first pivot axis to be selectively engaged and disengaged with the catch.

There is provided an anti-siphon device for securing in a fluid tank inlet. The anti-siphon device comprises a housing, an inlet to the housing adapted to receive a fluid dispensing nozzle, the inlet at a proximal end of the hosing, and an outlet at a distal end of the housing. The anti-siphon device further comprises an obstruction disposed within the housing, where an outer surface of the obstruction and an inner wall of the housing define a first flow passageway. The obstruction comprises, a chamber disposed within the obstruction and configured to receive fluid, an inlet aperture in a first portion of the obstruction, and an outlet aperture in a second portion of the obstruction, where the inlet aperture, chamber, and outlet aperture define a second flow passageway, the second flow passageway being configured such that, in use, fluid can flow from the inlet aperture to the outlet aperture via the second flow passageway, whilst fluid flows from the inlet to the outlet via the first flow passageway.

An anti-siphon device and method for operation of an anti-siphon device is provided. The anti-siphon device includes a plurality of radially aligned fins that are unsupported at one end and attached to a carrier body at a second end.

A hydrogen discharge device for a motor vehicle has at least one outlet for hydrogen. The hydrogen discharge device is arranged below the vehicle hood such that when the vehicle hood is closed, the outlet cannot be accessed and when the vehicle hood is open, the outlet can be accessed.

The present invention provides system (100) for securing fuel of motor vehicles using IoT devices. The system comprises control device (101) mounted on lid of fuel tank to control the opening and closing of the lid of the fuel tank, from remote places. The control device (101) comprises plurality of IoT sensors connected to a microcontroller unit (205), a GSM module (202) to transfer the data between the authorized user and control device (101). The control device (101) also comprises microcontroller unit (205) to execute the plurality of operations and motor (207) integrated with microcontroller unit (205) to lock or unlock the lid of the fuel tank on receiving the signal from authorized user. An application is installed onto the user's mobile device (104) to monitor and track the activities in fuel tank. A cloud based database server (103) is used for storing and analyzing the measured fuel data.

One embodiment of a molded fuel tank includes a fuel tank molded as one piece of rotationally molded cross-linked polyethylene material. One embodiment may include molding a fuel tank wall as a single layer of material with a metal component fastening structure positioned within the single layer fuel tank wall as it is molded.

A locking system for a fuel compartment assembly of a work vehicle, the locking system having a housing at least partially defining a fuel access compartment, a door pivotally coupled to the housing and movable between an opened position, at which the door provides access to the fuel access compartment, and a closed position, at which the door blocks access to the fuel access compartment, and a locking assembly configured to lock the door at the closed position. The locking assembly includes a catch fixed to the housing and positioned within the fuel access compartment, and a latch arm pivotably coupled to the door at a pivot point defined between first and second ends of the latch arm, the pivot point defining a first pivot axis, where the latch arm is configured to be pivoted about the first pivot axis to be selectively engaged and disengaged with the catch.
