ABSTRACT:
The rear face of the piston (7) and the corresponding inner face of the pump body (1,2,3,4) are complementarily shaped so as to make the volume of the rear chamber (31) of the cell as small as possible, and, when the cell is in the storing position, the unit of the two front (32) and rear (31) chambers is insulated from the outside by a high-efficiency seal (3a,6a) which is formed automatically when the piston (7) arrives in the storing position.
Measurements of the thermodynamic characteristics of the fluid deposits.
