Abstract: The method of maintaining a first flow rate through a first valve in a fluid delivery system, the fluid delivery system including a and a plurality of fluid valves in fluid communication with the pump, and a controller controlling the pressure generated by the pump and the position of the plurality of valves. The method includes providing the first flow rate of a fluid pressurized by the pump through the first valve, receiving a request for a second flow rate of the fluid through a second valve, determining a predicted effect on the first flow rate based on the request, adjusting at least one of the position of the first valve and the pressure generated by the pump to maintain the first flow rate based on the predicted effect, and adjusting the position of the second valve to provide the second flow rate of the fluid through the second valve.

Abstract: A firefighting monitor that has a first section, a second section joined to the first section by a first pivot connection, and a plurality of ball bearings positioned in the first pivot connection between a pair of bearing seats. Wherein, the bearing seats define an arc of contact with each of the plurality of ball bearings, the center of the arc of contact defining a tangent angled with respect to a flow axis defined by the first pivot connection.

Abstract: A device including a monitor assembly having an outlet configured to selectively distribute a fire suppressant there from, the outlet being pivotal about a first axis and a second axis, a cover coupled to the monitor assembly, and a light assembly coupled to the cover. The light assembly illuminates indicia on a lens of the light assembly.

Abstract: A control system for a fire fighting device is provided. The control system may include a controller configured to operably connect over a network to a first valve controller controlling a status of a first valve in response to an input from the controller, a second valve controlling a status of a second valve in response to an input from the controller, and a governor operably controlling a power source in response to an input from the controller. The control system may further comprise a touchscreen display operably connected to the controller, the display configured to display the status of the first and second valves and configured to receive an input from a user, wherein controller generates a manipulatable icon displayed on the touchscreen display, a manipulation of the icon generating the input from the controller to the first valve controller.

Abstract: A firefighting nozzle of the present invention includes a nozzle body with an inlet and an outlet, a passageway having a smooth bore extending between the inlet and the outlet of the nozzle body, and a compressible member defining at least a portion of the passageway. The compressible member has an inner dimension transverse to the longitudinal central axis. The nozzle also includes an adjuster mounted about the compressible member for selectively compressing the compressible member, wherein the pressure of the fluid flowing into the nozzle applies an outwardly directed pressure on the compressible member to thereby increase the inner dimension of the compressible member, and with at least a portion of the pressure being diverted from the passageway for applying an inwardly directed pressure on the compressible member to thereby at least reduce the force needed to be applied by the adjuster to counter-act the outwardly directed pressure when adjusting the flow rate of the nozzle.

Abstract: An inline foam eductor includes a first conduit having an upstream end, a downstream end, and a restriction between the upstream end and the downstream end, a second conduit in fluid communication with the first conduit downstream of the restriction between the restriction and the downstream end of the first conduit wherein fluid flowing through the first conduit through the restriction generates a venturi effect to thereby form a vacuum pressure in the second conduit, and a foam supply conduit in fluid communication with the second conduit. A metering device is operable to reduce the vacuum pressure in the second conduit to adjust the amount of foam drawn from the foam supply conduit into said first conduit through the second conduit.
