Abstract
Safe filling is provided by a housing (8) controlling the pump (6) of the mobile tank (1) receiving, via a secondary hose (10), the pressure prevailing in the container (2) to be filled, a programmable logic enabling the pump to operate when the pressure measured in the container is within a predetermined range, adaptable according to the type of container. The invention is applicable in particular to gas containers.
Claims5
1-4. (canceled)
5:
- A system for filling a cryogenic fluid storage tank from a mobile tank comprising a pressurized-fluid supply pump that can be connected via a filling hose to a fluid inlet of the storage tank, wherein the mobile tank comprises a pump control unit including a pressure sensor that can be connected to a pressure tapping of the storage tank, and programmable logic allowing the pump to operate when the pressure measured in the storage tank lies within a predetermined range.
6:
- The system of claim 5, wherein the control unit is connected to a secondary hose that can be connected selectively to the pressure tapping of the storage tank.
7:
- The system of claim 5, wherein the filling hose comprises a manually-disengageable non-return valve device.
8:
- The system of claim 5, wherein the cryogenic fluid is a gas from the air.
