Abstract
A combination carrying handle and control valve for firefighting apparatus suspends a portable reservoir. A handle is formed by a tubular wall having an inlet end and an outlet end and forming a flow passage between the ends; and a coupling is fastened to the inlet end and another coupling is fastened to the outlet end for connecting the handle to a source of liquid under pressure and to an accessory, respectively. A manually operated flow control valve is mounted in the handle for controlling the flow of liquid. The handle is part of a tank that may contain a liquid additive, and an eductor is connected between the flow passage and the tank interior for drawing the additive from the tank.
