Abstract (en)
[origin: FR2630785A1] A device for pumping a multiphase fluid comprises in combination an intake pipe (13) for the fluid to be pumped and a delivery pipe (19) for the pumped fluid, at least one variable volume chamber (2) suitable for pumping said fluid, said chamber being defined by a first cylinder head (3), a first cylinder (4) and a first piston (5), said piston sliding along the axis of the cylinder (4) in the latter, and at least a first drive element (6) capable of displacing said piston in said cylinder. The device also comprises a housing (23) enclosing at least the space swept by the piston (5), said space being opposed with respect to said piston to said first chamber, said housing also containing a gaseous fluid. Also disclosed is a piston (5) comprising a recess (20) for accommodating a projection (10) integral with the cylinder head (3), these two elements producing a set of fluid directed to an outlet orifice (15).
