The invention involves a water gun (1; 101) having at least one pressurizable air/water storage tank (13; 188, 189) and a release mechanism including a plug valve (35; 135). The release mechanism also has a first spring (37; 137) connected to the plug valve which biases the plug valve to a closed position. There is also a delay spring (61; 161) located within a linkage (53, 55, 57, 59, 61, 153, 155, 157, 159, 161) that overcomes the forces of the first spring (37; 137) and internal water pressure holding the plug valve closed, such that the plug valve snaps open and there is rapid decrease of water pressure causing a burst of water to exit the water gun. When the delay spring can no longer overcome the internal pressure, the plug valve snaps closed. This creates a controllable burst and a realistic trigger release.
Canon d'arrosage (1, 101) doté d'au moins un réservoir de stockage d'air/d'eau pressurisable (13, 188, 189) et d'un mécanisme de déclenchement muni d'une soupape à boisseau (35, 135). Le mécanisme de déclenchement comprend également un premier ressort (37, 137), relié à la soupape, qui maintient cette dernière en position fermée. Un ressort à retardement (61, 161) situé dans un raccordement (53, 55, 57, 59, 61, 153, 155, 157, 159, 161) sert à résister aux pressions du premier ressort (37, 137) et de l'eau interne qui maintiennent la soupape fermée et à provoquer l'ouverture d'un coup sec de la soupape, ce qui entraîne la diminution rapide de la pression de l'eau, de sorte qu'elle est expulsée du canon d'arrosage en rafale. Lorsque le ressort à retardement ne peut plus résister à la pression interne, la soupape se ferme d'un coup sec, ce qui permet de créer un jet réglable et un déclenchement réaliste.
