Distributor for a mobile plant treatment spraying installation.

摘要

The distributor comprises a device for adjusting the spraying pressure, consisting, according to the invention, of a needle valve (27) which can be manoeuvred from outside by a rod (25) and interacts with a seat (31); the latter is mounted slidably in a casing (21) so as to move away from the needle valve (27) in the event of an excess pressure in the casing (17) of the distributor; a spring (29) returns the seat (31) into its initial position when the excess pressure has been cancelled out. <IMAGE>
