ABSTRACT:
A liquid-projecting monitor of the spherical head type has its head sealing against a housing which defines together with the head a chamber from which liquid is lead into a passage in the head and then to a nozzle coupled to the head. The head is borne by a horizontal axle for pivotal movement relative to the housing so as to adjust the angular elevation or depression of the nozzle. A center body extends transversely across the interior of the head to enclose the axle and is so shaped, together with the internal surface of the head, that the cross-sectional area of the passage within the head available for liquid flow is maintained at least approximately constant throughout its length, so as to minimize the pressure drop in the liquid flow which passes through the head.
