Abstract: Liquid pump (1) comprising: a cylinder (24), an inlet valve (47a) for feeding the liquid into said cylinder (24), a discharge valve (47b) for discharging the liquid out of said cylinder (24), a piston (52) actuated by a transmission tube (51) and sliding in said cylinder (24) so as to draw said liquid into said cylinder (24) and then to expel it from said cylinder (24). The cylinder (24) comprises at least one heating cartridge (41) in order to heat the liquid in said cylinder (24).

Abstract: A liquid pump that includes a cylinder (2), an inlet valve (4) for feeding liquid into the cylinder, and a discharge valve (5) for discharging the liquid out of the cylinder. The liquid pump also includes a piston (3) sliding in said cylinder so as to draw said liquid into said cylinder and to expel the same outside the cylinder. Additionally, the liquid pump includes an electric circuit (7) for heating the cylinder, with at least one resistor (70, 71) for electrically heating the liquid in the cylinder. The resistor (70, 71) may be made in the form of an electrically conducting thin track deposited on or in the wall (20) of the cylinder (2). The heating may be initiated before the introduction of the liquid into the cylinder, and interrupted before the full discharge of the liquid out of the cylinder.
