Title (EN) ADJUSTABLE POSITIVE-DISPLACEMENT PUMP
(FR) POMPE VOLUMETRIQUE REGLABLE
Abstract:
(EN) 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.
(FR) L'invention concerne une pompe volumétrique réglable, du type pistolet (1 ) comprenant une crosse (2) formant poignée de saisie et un canon (5) comportant au moins un réservoir (6) de pompe, un piston (9) monté coulissant axialement à l'intérieur du réservoir et des moyens de réglage de la course du piston (9) comprenant une pièce (11 ) rotative munie d'une pluralité de butées (12) décalées angulairement et positionnables sélectivement, par rotation de ladite pièce (11 ), en regard d'une saillie (10) radiale externe équipant ledit piston (9). Cette pompe est caractérisée en ce que la pièce (11 ) porte-butées est disposée sur le canon (5) du pistolet en une zone (13A) dite du dessus du canon opposée à la zone (13B) du canon solidaire de la crosse (2) et est montée à rotation autour d'un axe (XX') orthogonal à l'axe (YY') longitudinal du piston (9), la succession de butées d'arrêt disposées côte à côte de ladite pièce formant une surface (14) d'allure spiralée s'enroulant autour de l'axe (XX') de rotation de ladite pièce.
