Definitions
- Pressure vessel Pressure vessel, pressure vessel system and motor vehicle with fuel rail
- the technology disclosed here relates to a pressure vessel system for a motor vehicle (eg passenger cars, motorcycles, commercial vehicles).
- the pressure vessel system includes at least one pressure vessel for storing fuel.
- the pressure vessel system is used to store fuel that is gaseous under ambient conditions.
- the pressure vessel system can be used, for example, in a motor vehicle that is operated with compressed (also called Compressed Natural Gas or CNG) or liquefied (also called Liquid Natural Gas or LNG) natural gas or with hydrogen.
- compressed also called Compressed Natural Gas or CNG
- liquefied also called Liquid Natural Gas or LNG
- the pressure vessel system is fluidly connected to at least one energy converter which is set up to convert the chemical energy of the fuel into other forms of energy, eg a fuel cell or an internal combustion engine.
- the technology disclosed herein relates to a pressure vessel.
- the pressure vessel can be a high-pressure gas vessel, for example.
- NWP nominal working pressure
- the pressure vessels can have circular or oval cross-sections.
- several pressure vessels can be provided, the longitudinal axes of which run parallel to one another in the installed position.
- the individual pressure vessels can each have a length-to-diameter ratio with a value between 5 and 200, preferably between 7 and 100, and particularly preferably between 9 and 50.
- the length-to-diameter ratio is the quotient of the total length of the individual pressure vessels (e.g. total length of a storage tube without fluid connectors) in the numerator and the largest outside diameter of the pressure vessel in the denominator.
- the individual pressure vessels can be arranged directly adjacent to one another, for example at a distance from one another of less than 20 cm or less than 15 cm or less than 10 cm or less than 5 cm.
- the plurality of pressure vessels may each be mechanically coupled to one another at one or both ends.
- body connection elements common to the plurality of pressure vessels are provided at both ends, by means of which the pressure vessels can be fastened in the motor vehicle.
- Such a system is particularly suitable for flat installation spaces, especially in the underfloor area below the vehicle interior.
- the pressure vessel includes a fitting.
- the connection piece forms the pressure vessel opening of the pressure vessel. ldR the connection piece is provided at one end of the pressure vessel.
- the connector is preferably made of metal and is often referred to as the "boss".
- the connecting piece is expediently provided coaxially to the longitudinal axis of the pressure vessel.
- the connection piece is used to form a fluid connection between the fuel storage volume of the pressure vessel and the energy converter of the motor vehicle. A part of the connection piece is led out of the pressure vessel. Another part can be integrated into the container wall.
- the connecting piece is attached to the outside of the pressure vessel.
- the connecting piece can have a section that protrudes into the container wall and is surrounded by a fiber-reinforced layer.
- the connector includes an end face that is regular essentially parallel to a plane which is oriented perpendicularly to the longitudinal axis of the pressure vessel.
- the side faces of the connecting piece are provided laterally to the end face.
- a pipe rupture safety valve can be provided in the fuel storage volume or in the connection piece of the at least one pressure vessel, which valve prevents fuel from flowing out of the pressure vessel in the event of a fault.
- a pipe rupture safety valve prevents the uncontrolled release of fuel in the event of a line rupture in the downstream line system of the fuel supply system and can be reset automatically when the fault has been rectified.
- the part of the outer surface of the connecting piece that leads out of the pressure vessel comprises a sealing surface and a curved fastening surface.
- the outer surface of the portion of the fitting protruding from the pressure vessel has a sealing surface.
- the sealing surface can be designed as a truncated cone surface or a funnel-shaped surface that tapers into the connecting piece.
- the sealing surface is set up to seal off the fluid connection between the pressure vessel and a fuel-carrying section of the motor vehicle when the pressure vessel is in the installed position.
- an outer surface of the fuel-carrying section can contact the sealing surface of the connection piece directly or with the interposition of a sealing element.
- the outer surface of the fuel-carrying section is preferably a curved and particularly preferably spherical segment-shaped outer surface, which contacts the sealing surface at least in regions.
- a good sealing seat can be produced.
- the pressure vessel can thus also be aligned with simple means.
- the outer surface of the part of the fitting protruding from the pressure vessel also has a curved attachment surface.
- the attachment surface can be formed by a surface section of a spherical segment or a cylinder.
- the attachment surface is provided for the direct or immediate attachment of the pressure vessel to at least one body connection element.
- the at least one body connection element is used for direct or indirect attachment of the pressure vessel to the body of the motor vehicle and can have any suitable shape.
- the connection piece or the body connection element is/are designed to transfer the forces and moments resulting from the operation of the motor vehicle from the pressure vessel to the body of the motor vehicle at the respective end at which the connection piece is provided.
- the body connection element can have a curved inner surface, preferably in the shape of a segment of a sphere, the curvature of which essentially corresponds to the curvature of the outer surface of the fastening surface in order to form a contact surface.
- the fastening surface and the sealing surface are expediently provided on the side of the part of the connecting piece that is led out of the pressure vessel.
- the connecting piece can expediently comprise an end face which is arranged in a plane which runs essentially perpendicularly to the longitudinal axis of the pressure vessel.
- the part of the connection piece that is led out of the pressure vessel can also comprise peripheral surfaces on which the (lateral) outer surfaces are provided, wherein the fastening surface and the sealing surface can be provided on these peripheral surfaces.
- the peripheral surfaces can expediently run at right angles to the end face.
- the fastening surface and the sealing surface can be arranged opposite one another in such a way that in the installed position the fastening surface and the sealing surface can be braced against one another by at least one clamping means (eg screws).
- the fuel-carrying section and the body connection element can preferably clamp the part of the connecting piece that is brought out to form a bearing point.
- the connecting piece and in particular the fastening surface are therefore used to mount the pressure vessel in the motor vehicle. Such storage over the end of the pressure vessel is also referred to as a "neck mount".
- the fuel system or the pressure vessel can be set up such that the fuel can flow in or out at the end of the pressure vessel via a fluid channel running laterally and in particular perpendicular to the longitudinal axis of the pressure vessel.
- the sealing surface In the installed position of the pressure vessel, the sealing surface can rest against the fuel-carrying section at sealing surface contact points. In the installed position of the pressure vessel, the fastening surface can make contact with the body connection element in fastening surface contact points.
- the angular deviation is the deviation of the actual installation position of the pressure vessel from a target installation position in relation to the longitudinal axis of the pressure vessel. It is regularly provided that the opening of the pressure vessel and the sealing surface surrounding it is always arranged in the same position during assembly. Deviations from this ideal situation occur due to unavoidable tolerances. With regard to the rotation around the longitudinal axis of the pressure vessel, this deviation can occur the angular deviation can be described.
- the sealing surface and the fastening surface can be arranged and designed in such a way that with different angular deviations A (i) the sealing surface contact points and the fastening surface contact points are each formed at different points and (ii) the entirety is off sealing surface contact points resulting from different angular deviations A and the entirety of fastening surface contact points resulting from different angular deviations A each have curved surfaces with at least one common pivot point.
- the fluid connection between the section and the pressure vessel can be established without leakage even with different angular deviations A.
- comparatively good interference fits can also be achieved for mounting the pressure tank via the sealing surface and the curved surface, even with different angular deviations A.
- the fuel-carrying section is used to fill the pressure vessel with fuel and/or to remove fuel from the pressure vessel.
- the pressure in the fuel-carrying section preferably essentially corresponds to the internal pressure of the pressure vessel.
- the individual pressure vessels are regularly connected in parallel.
- the multiple pressure vessels are in fluid communication with one another or with one another without interruption.
- “uninterrupted” means that no valve is provided between the individual pressure vessels that would interrupt this fluid connection during error-free operation.
- the fuel pressure in the various pressure vessels generally has essentially the same value.
- the at least one fuel-carrying section can preferably be designed as a fuel rail.
- the fuel rail may also be referred to as a high pressure fuel rail.
- such a fuel rail can be configured similarly to a high-pressure injection rail of an internal combustion engine.
- the fuel rail expediently includes a number of rail connections for direct connection of the pressure vessels.
- the individual strip connections are advantageously provided directly on the strip housing and/or all have the same spacing from one another.
