NOZZLE Russian patent published in 2018 - IPC B05B1/08 B05B15/00 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to mechanical engineering and is intended for spraying liquids into the dusty working zone of road construction, mining and peat mining, agricultural machinery and equipment. Nozzle includes a housing with an inlet and an outlet, a stem and a locking element. Body is equipped with a sprayer with a bore and equidistant from the axis of the housing holes, guiding the cylindrical rod for the installation of the locking element and the cam shaft. Inlet flow channel is made through a non-return valve with a tank. Inside the housing, a groove is provided on its end surface communicating with the inlet fluid supply channel and a cavity with a spring-loaded plunger therein. Sealing of the mating surfaces of the housing and the spring-loaded plug is provided with sealing rings. Between the nozzle and the end of the housing there is a lock washer with holes equally spaced from the housing axis and a locking element made in the form of a spring-loaded locking plate. Plate is provided on one side with fixed stems to clean the holes of the spray gun from mechanical impurities, and on the other hand – a stationary elastic ring covering the holes of the lock washer. Cam shaft with an eccentricity equal to the full stroke of the plunger is mounted on rolling bearings, the cavity of which is closed by lids. On the body of the nozzle is installed lubrication oil for lubrication of bearings.

EFFECT: technical result of the invention is to increase the operating reliability of the nozzle.
