Definitions

  • the invention relates to a cryo-refueling arrangement and a method for operating such a cryo-refueling arrangement.
  • a cryogenic refueling system comprises a storage container which can be coupled to a storage container of the vehicle with the aid of a refueling hose or pipe, a coupling device provided on the refueling hose or pipe and a receiving socket provided on a vehicle, so that the vehicle can be supplied with cryogenic media, such as hydrogen, can be refueled.
  • the coupling device is locked to the receiver socket by means of a locking device. This locking is done manually, so that it can only be unlocked manually. In an emergency, for example if there is a leak, this can mean that the lock can no longer be released safely.
  • a cryo-fuelling arrangement with a coupling device and a receiver nozzle is proposed.
  • the coupling device and the receiver port are designed to complement one another, with the cryo-fueling arrangement being in an unlocked state in which the coupling device and the receiver port are accommodated in one another at least in sections, so that the coupling device and the receiver port form an intermediate space that is closed off from the environment of the cryo-fueling arrangement , which is arranged between an end face of the coupling device and an end face of the receiver socket, can be brought into a locking state with the aid of a pressure change in the intermediate space, in which the end face of the coupling device is pressed against the end face of the receiver socket due to the pressure change.
  • a cryo-fuelling arrangement with a coupling device and a receiver nozzle is proposed.
  • the cryo-refuelling arrangement is in an unlocked state, in which the coupling device is accommodated in the receiver socket in such a way that an intermediate space is provided between the coupling device and the receiver socket, which is closed off from an area surrounding the cryo-refuelling arrangement, with the aid of a pressure change in the intermediate space into a Locked state can be brought, in which the coupling device is pressed due to the change in pressure against the receiver port.
  • cryogenic refueling arrangement can be brought from the unlocked state into the locked state with the aid of the pressure change in the intermediate space, manual unlocking can be dispensed with.
  • the coupling device By pressurizing the intermediate space, the coupling device can be separated from or ejected from the receiver connection piece in a simple and automated manner.
  • the cryogenic refueling arrangement can also be referred to as a cryogenic refueling arrangement.
  • the coupling device may also be referred to as a clutch, hydrogen coupling device, or hydrogen coupling.
  • the coupling device is adapted to be received in a vehicle's receiver socket for refueling the vehicle.
  • a tank hose is assigned to the coupling device.
  • the tank hose can be part of the coupling device.
  • the coupling device In the unlocked state, the coupling device is in particular received in the receiver connector to such an extent that the intermediate space is provided on the face side between the coupling device and the receiver connector.
  • the receiver socket can also be accommodated in the coupling device.
  • a vacuum or negative pressure is preferably applied to the gap. This change in pressure creates a force that pulls the coupling device and receiver port together.
  • the coupling device While the cryo-refuelling assembly is in the unlocked state, the coupling device can be withdrawn from the receiver port. Only when the intermediate space is subjected to the change in pressure is the cryogenic fueling arrangement brought into the locked state. In the locked condition, the vacuum prevents the coupling device from self-disengaging from the receiver port. Thus, the force created by the pressure change locks the coupling device to the receiver port. In the unlocked state, the coupling device provides a fluid-tight seal with respect to the receiver port, so that the intermediate space is isolated from the environment.
  • “Due to pressure” or “due to the force generated by pressure” means in particular that the change in pressure or the force acting in the now closed gap is the cause of the coupling device being pressed against the receiver socket.
  • the gap is preferably closed. That is, the gap no longer exists in the locked state.
  • the coupling device is pressed or pressed against the receiver port with the aid of the force caused by the pressure change.
  • a “change in pressure” is preferably to be understood as meaning a pressure reduction, in particular the creation of a vacuum.
  • the fact that the coupling device and the receiver connection piece are “complementary” to one another means in particular that the coupling device and the receiver connection piece can be plugged into one another, preferably in the manner of a plug connection.
  • the coupling device and the receiver socket each have a similarly shaped geometry, which allows such a plugging into one another.
  • the coupling device has a cylindrical geometry and the receiver socket has a complementary hollow-cylindrical geometry. In this case, either the coupling device can be plugged into the receiver socket or the receiver socket can be plugged into the coupling device.
  • “receive” can in particular be understood to mean “insert” or “insert into one another".
  • the coupling device be male and the receiver socket female or vice versa.
  • male means that the coupling device is suitable for being received in the receiver socket.
  • female as used herein with reference to the receiver socket means that the receiver socket is suitable for accommodating the coupling device.
  • the fact that the coupling device and the receiver connection piece are "accommodated in one another" can in particular mean that either the coupling device is accommodated in the receiver connection piece or, conversely, that the receiver connection piece is accommodated in the coupling device.
  • the intermediate space is preferably delimited or enclosed by the two end faces and a peripheral receiving section which is provided on the coupling device or on the receiver socket.
  • the intermediate space is sealed off from the environment in particular in a fluid-tight, preferably gas-tight manner.
  • Fluid-tight means in the present case that no fluid can escape from the intermediate space into the environment and also that no fluid can enter the intermediate space from the environment.
  • the first end face and the second end face are in contact with one another, in particular over an area.
  • “Flat” here means with the largest possible surface and is to be seen in contrast to a line contact or a point contact or a line contact or a point contact.
  • the first end face can also be referred to as the first end face.
  • the second end face can be referred to as the second end face.
  • the coupling device has a counter-receiving section, wherein the receiver connector has a receiving section complementary to the counter-receiving section, and the counter-receiving section is at least partially received in the receiving section both in the unlocked state and in the locked state.
  • the counter-receiving section can also be provided on the receiver socket and the receiving section can be provided on the coupling device.
  • the counter-receiving section and the receiving section are each cylindrical.
  • the counter-receiving section and the receiving section are each in the form of a hollow cylinder.
  • the counter-receiving section can be accommodated in the receiving section.
  • the counter-receiving section and the receiving section can also each be designed to be polygonal, for example hexagonal, or star-shaped.
  • first end face and the second end face are each ring-shaped.
  • annular is to be understood as meaning that the first end face and the second end face are each closed circumferentially.
  • the faces may also be referred to as faces or are faces.
  • the first end face is provided on a housing of the coupling device, with the second end face being provided on a housing of the receiver socket.
  • an end face of the coupling device rests against an end face of the receiver socket, with the intermediate space being arranged between the face side of the coupling device and the face side of the receiver socket in the unlocked state.
  • the receiver socket comprises a receiving section for receiving the coupling device at least in sections.
  • the receiving section can be cylindrical, in particular tubular. Viewed in a radial direction, the intermediate space is delimited circumferentially by the receiving section. Viewed in the axial direction, the intermediate space is delimited by the end faces.
  • the cryo-fuelling arrangement also includes a unit for generating the pressure change in the intermediate space.
  • the unit can be a vacuum pump.
  • the unit is preferably assigned to the coupling device. However, the unit can also be assigned to the recipient socket.
  • the cryo-refuelling arrangement further comprises a locking device for locking the coupling device in the receiver nozzle as soon as the cryo-refuelling arrangement is in the locking state.
  • the cryo-refuelling arrangement further comprises a locking device for locking the coupling device and the receiver nozzle once the cryo-refuelling arrangement is in the locking state.

  • the connection of the coupling device and the receiver socket and the disconnection of the coupling device from the receiver socket can be automated.
  • the locking device comprises an engagement element and a counter-engagement element, in which the engagement element engages in a form-fitting manner in the locking state.
  • a form-fitting connection is created by the meshing or rear gripping of two connection partners, in this case the engagement element and the counter engagement element.
  • the engagement element can be a bolt, for example.
  • the counter-engagement element can be a recess or bore.
  • the locking device is activated electrically, electromagnetically, mechanically, pneumatically or hydraulically.
  • a method for operating a cryogenic refueling arrangement with a coupling device and a receiver nozzle is proposed.
  • the coupling device and the receiver socket are designed to be complementary to one another.
  • the method comprises the following steps: a) receiving the coupling device and the receiver connection piece in one another in sections, so that the coupling device and the receiver connection piece form an intermediate space which is closed off from the surroundings of the cryogenic refueling arrangement and is arranged between an end face of the coupling device and an end face of the receiver connection piece, enclose, and b) generating a pressure change in the intermediate space, so that the end face of the coupling device is pressed against the end face of the receiver connection due to the pressure change.
