ABSTRACT:
A spraying device includes a nozzle head formed with an axial bore connectible to a source of pressurized liquid, an outlet orifice through which the liquid exits in the form of a jet, and a connecting passageway connecting the inlet end to the outlet orifice. A rod passes through the axial bore; and a liquid distribution member is secured to the rod at the outlet orifice to distribute the liquid laterally of the nozzle head. The rod carries an abutment at the bore inlet end and is displaceable axially and laterally within the bore. The connecting passageway of the axial bore, and the adjacent portion of the rod, include complementary conical surfaces defining between them a metering passageway for the liquid flowing to the outlet orifice such that, during operation of the spraying device, the axial position of the rod within the bore, as determined by the abutment, determines the output rate of the spraying device.
