Abstract

The invention relates to an adjustable pistol positive-displacement pump (1) including a gripping handle butt (2) and a barrel (5) including at least one pump tank (6), a piston (9) mounted so as to axially slide within the tank, and a means for adjusting the piston (9) stroke, including a rotary part (11) provided with a plurality of abutments (12) angularly offset and selectively positioned by the rotation of said part (11) opposite an outer radial protrusion (10) on said piston (9). The pump is characterised in that the abutment-bearing part (11) is provided on the barrel (5) of the pistol at an area (13A) above the barrel opposite the area (13B) of the barrel connected to the butt (2), and is mounted so as to be rotatable about an axis (XX') orthogonal to the longitudinal axis (YY') of the piston (9), the series of abutments arranged side by side relative to said part forming a surface with a spiralled aspect that is wound about the rotational axis (XX') of said part.
