Foam generating device for a high-pressure water gun

A foam generating device for a high-pressure water gun, the device comprising:

• a supporting body;
• a main inlet provided at said supporting body;
• a secondary inlet;
• a nozzle defining an outlet and adjustable so as to vary an outgoing water flow between a fan-shaped jet and a solid stream jet;
• a conduit extending along an axis from said main inlet to said outlet and comprising a mixing chamber communicating with said secondary inlet and subject, in use, to a vacuum for aspirating a liquid through said secondary inlet;
• a first body, fitted around said supporting body, positioned in a fixed axial position and rotatable about said axis in relation to both said main inlet and said secondary inlet;
• said nozzle being arranged in fixed angular position with respect to said first body;
• a second body which is arranged in a fixed axial position and is rotatable about said axis with respect to said first body and with respect to both said main inlet and said secondary inlet;
• the second body comprising adjustment portions for adjusting said nozzle in response to a rotation of said second body with respect to said first body;
• wherein said first body is kept in its fixed axial position by a pin portion engaging a slot which is axially fixed with respect to said supporting body.
