Patent ID: 7121527

Claim:
An intercept valve for spray guns for water cleaner apparatus, comprising: a first body ( 4 ), preferably having a longitudinal development, internally exhibiting a cavity ( 6 ) and having upstream thereof a first section change ( 7 ) facing a fluid inlet conduit ( 3 a ) and having downstream thereof a second section change ( 8 ) facing a fluid outlet conduit ( 3 b ), the inlet conduit ( 3 a ) and the outlet conduit ( 3 b ) being coaxial along a longitudinal axis (X—X); a second body ( 5 ), developing transversally with respect to the first body ( 4 ) and communicating with the cavity ( 6 ) through a through hole ( 25 ) ending in proximity of the cavity ( 6 ) with a section narrowing ( 32 ); a first annular body ( 9 ) and a second annular body ( 10 ) located respectively in the first section change ( 7 ) and the second section change ( 8 ), being provided, respectively with a first opening ( 11 ) and a second opening ( 12 ); an obturator ( 14 ) developing longitudinally and being conformed as a body of rotation according to an axis (Y—Y), and being arranged internally of the cavity ( 6 ), having a first tract ( 15 ) which exhibits a striker element ( 19 ) and a second tract ( 16 ) exhibiting a first side ( 17 ) in at least partial contact with the second annular body ( 10 ); elastic means ( 21 ), arranged internally of the cavity ( 6 ) and acting on the obturator ( 14 ) by means of the striker element; means for activating ( 26 ) the obturator ( 14 ), located internally of the second body ( 5 ) and terminating, through the through hole ( 25 ), in contact with the obturator ( 14 ); characterised in that the obturator ( 14 ) defines a closed-valve position when the axis (Y—Y) of the intercept valve ( 1 ) is parallel to the axis (X—X) of the first body ( 4 ) and defines an open-valve position when, following action of the means for activating ( 26 ), the axis (Y—Y) of the obturator ( 14 ) assumes an angled position with respect to the axis (X—X).
