Embodiment Construction

[0028] Hereinafter, the term "liquefied gas" refers to liquefied natural gas (LNG) or liquefied biogas (LBG).

[0029] Hereinafter, the term "liquefied gas fuel system" refers to a fuel system for liquefied natural gas (LNG) or for liquefied biogas (LBG).

[0030] Hereinafter, the term "flexible pipe" refers to any flexible pipe, such as a hose, configured to convey fluid for use in a liquefied gas fuel system, which is bendable to a certain extent and has a certain flexibility in order to facilitate Handles the relative motion of the vehicle cabin relative to the liquefied gas fuel tank.

[0031] Hereinafter, the term "evaporation duct" refers to a duct, preferably a rigid duct, configured to discharge boil-off gas from a liquefied gas fuel tank of a liquefied gas fuel system. According to an 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) for mounting an evaporation line (20) of a liquefied gas fuel system (I) to a vehicle (1) with a tiltable cab (2). This evaporation duct is attached to the rear side of the cab (2) via the connection means (30) of said device (A1). The connection means (30) comprises a flexible tube (34) arranged to be connected at one end to the tank (10) mounted on the chassis of the vehicle and at the other end to the evaporation duct (20). The linkage (30) comprises a link arm formation (32; 132) comprising at least one link arm (32a) arranged to be pivotally connected at one end (32a-1) to the cab (2) wherein said link arm formation (32) is arranged to support said flexible tube (34) to accommodate tilting movement 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 cope with relatively low temperatures, eg -130 degrees Celsius at 10 bar for LNG, requiring specific conduits for transporting the LNG and specific tanks for containing the fuel. When the vehicle is stationary and the engine is not operating, the pressure in the tank will increase due to the increased temperature in the tank. Therefore, the system for liquefied gas is equipped ...
