SELF-REGULATING DISCHARGE OUTLET OF SPRAY CONDUIT Russian patent published in 2009 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: invention relates to a technique of watering agricultural crops by a drop method by means of flexible spray conduits. The self-regulating discharge outlet of a spray conduit includes a hole in the conduit wall and water outlets made as a travelling valve composed of a cone-shaped locking head. The locking head leans on the internal wall of the conduit by means of a viscoelastic plate having discharge openings whose number and diametre are designed for admission of the nominal consumption through the water outlet. There is a compensatory groove in connection of the locking head with the plate. On the external surface of the conduit the locking head is secured by the viscoelastic plate with discharge openings whose axes are directed towards the axial line of the water discharge opening in the conduit wall.

EFFECT: accurate metering of the nominal water consumption depending on the discharge head in the conduit, design simplification.
