Claims12
A module for depressurisation, collection and storage of a portion of a gas layer coming from at least one vehicle cryogenic tank the cryogenic tank comprising at least one valve, the gas layer being the gaseous phase of a gas energy source, the cryogenic tank containing, apart from the gas layer, a liquid layer that is the liquid phase of a gas energy source,
- the module being characterised in that it constitutes a sealed assembly comprising:
- an inlet intended to be connected, by a removable inlet pipe, to at least one orifice of the tank for the discharge, out of the cryogenic tank, of a portion of gas layer, the orifice being fitted or not with a valve.
- an outlet intended to be connected, by a removable outlet pipe, to an external system suitable for using the portion of gas layer once discharged,
- a heater connected to the inlet of the module,
- a damping buffer tank, connected to the heater, and also to
- a compressor, connected to the buffer tank, and also to
- a storage connected to the outlet of the module, the storage making it possible to store the portion of gas layer discharged.
