An expandable bladder toy water gun (1) is provided. It includes a main housing (3) having a barrel (9), a water ejection nozzle (11), a handle (5), a trigger (7), a water storage tank (33), a hand pump (45) as well as an inflatable bladder (13) connected to the main housing (3). The pump (45) is connected to both the tank (33) and the bladder (13). There is a bladder release valve (31) with an upstream side connected to the bladder (13) and a downstream side connected to the nozzle (11) for water ejection when the trigger (7) is pulled. The elasticity of the bladder (13) is used as the motive force for liquid ejection. The bladder is a tubular member which has a section (91) of weakened elastic strength relative to the remainder of the member. In one embodiment, the bladder has a variable diameter, larger at its front end and smaller at its back end. In another embodiment, the bladder has a constant diameter with a wall thickness gradient. The nozzle (11) includes a turbulence control member (213) for enhanced laminar flow ejection which control member has a plurality of linear stream guidance walls.

La présente invention se rapporte à un jouet constitué par un pistolet à eau (1) muni d'une poche extensible. Ledit pistolet à eau comprend un corps principal (3) muni d'un canon (9), un gicleur d'eau (11), une poignée (5), une détente (7), un réservoir pour stocker l'eau (33), une pompe à main (45) ainsi qu'une poche extensible (13) reliée au corps principal (3). La pompe (45) est reliée au réservoir (33) et à la poche extensible (13) . Une valve de vidange (31) de la poche extensible est reliée en amont à la poche extensible (13) et en aval au gicleur (11), lequel éjecte l'eau lorsque la détente (7) est actionnée. L'élasticité de la poche extensible (13) constitue la force motrice qui éjecte le liquide. La poche extensible est un élément tubulaire dont une section (91) présente une limite d'élasticité inférieure à celle du reste de l'élément. Dans un mode de réalisation, la poche extensible est de diamètre variable, plus large à son extrémité antérieure et plus étroite à son extrémité postérieure. Dans un autre mode de réalisation, la poche extensible présente un diamètre constant avec un gradient d'épaisseur de paroi. Le gicleur (11) comprend un organe de tourbillonnement (213) permettant l'éjection d'un flux laminaire amélioré, ledit organe de tourbillonnement comprenant plusieurs parois de guidage de flux linéaire.
