Embodiment Construction

[0030] Hereinafter, the term "liquefied gas" refers to liquefied natural gas (LNG) or liquefied biogas (LBG).

[0031] Hereinafter, the term "liquefied gas fuel system" refers to a fuel system for liquefied natural gas (LNG) or for liquefied biogas (LBG).

[0032] Hereinafter, the term "flexible hose" refers to a hose configured to convey fluid for a liquefied gas fuel system, which is bendable to a certain extent and has a certain flexibility to facilitate handling of the relative The relative motion of the liquefied gas fuel storage tank.

[0033] Hereinafter, the term "evaporation line" refers to a line, preferably a rigid line, configured to discharge boil-off gas from a liquefied gas fuel storage tank of a liquefied gas fuel system. According to one embodiment, the pipe is made of stainless steel. Optionally, the evaporation conduit may be flexible, such as a flexible hose.

Abstract

The invention relates to a device (A1; A2; A3) for mounting an evaporation line (20) of a liquefied gas fuel system (I) to a vehicle (1) with a tiltable cab (2). Said evaporation duct (20) is connected to the rear side of the cab (2) via connection means (30; 130; 230) of said means (A1; A2; A3). The connecting device (30; 130; 230) comprises a coupling formation (32; 132; 232) for connecting the storage tank to the evaporation duct (20) in the non-tilted position of the cab (2) and to the cab (2) Tilt-related disconnection of the tank (10) from the evaporative duct (20), wherein the coupling formation (32; 132; 232) is arranged to connect to the cab (2) in said non-tilted position Tilting operating means (40; 140; 240) in order to prevent tilting of said cab (2). The invention also relates to a connection device assembly. The invention also relates to a vehicle.

Description

technical field [0001] The invention relates to a device for mounting an evaporation line of a liquefied gas fuel system to a vehicle according to the preamble of claim 1 . The invention also relates to a vehicle. Background technique [0002] Alternative fuels such as natural gas and biogas are being introduced in vehicles such as heavy duty vehicles. For this purpose, fuel systems for compressed natural gas (CNG) and compressed biogas (CBG) and fuel systems for liquefied natural gas (LNG) and liquefied biogas (LBG) are being developed. [0003] Systems for liquefied gases (ie LNG and LBG) need to handle relatively low temperatures, eg -130 degrees Celsius at 10 bar for LNG, requiring specific pipelines for transporting the LNG and specific tanks for storing the fuel. When the vehicle is stationary and the engine is not running, the pressure in the tank will increase due to the increased temperature in the tank. Therefore, the system for liquefied gas is equipped with a ...
