ULTRA HIGH PRESSURE WATER FIRE FIGHTING SYSTEM
First Claim
1. A fire fighting vehicle, comprising:
- a chassis;
an engine coupled to the chassis;
a fluid tank configured to store a fluid;
a fluid delivery system including;
a first pump coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure;
a second pump positioned downstream of and coupled to the first pump in a serial arrangement, the second pump selectively driven by the engine to increase the pressure of the fluid from the first pressure to a second pressure, the second pressure greater than the first pressure;
a low pressure discharge coupled to the first pump;
a first high pressure discharge coupled to the second pump; and
a second high pressure discharge coupled to the second pump; and
a controller configured to selectively vary at least one of a speed, a power output, and a torque output of the engine based on a mode of operation of at least one of the fire fighting vehicle and the fluid delivery system and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.

Abstract
A fire fighting vehicle includes a chassis, an engine coupled to the chassis, a fluid tank configured to store a fluid, a fluid delivery system, and a controller. The fluid delivery system includes a first pump, a second pump, a low pressure discharge, a first high pressure discharge, and a second high pressure discharge. The first pump is coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure. The second pump is positioned downstream of and coupled to the first pump in a serial arrangement. The controller is configured to selectively vary at least one of a speed, a power output, and a torque output of the engine and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.

14. A fluid delivery system for a fire fighting vehicle, the fluid delivery system comprising:
-
a low pressure discharge; a low pressure pump having an inlet configured to receive a fluid from a fluid tank of the fire fighting vehicle and an outlet coupled to the low pressure discharge; a high pressure pump having an inlet coupled to the outlet of the low pressure pump such that the low pressure pump and the high pressure pump are arranged in a serial configuration, wherein the high pressure pump is configured to be selectively driven by an engine of the fire fighting vehicle; and at least one of a turret and a hose reel coupled to an outlet of the high pressure pump, wherein the fluid delivery system is selectively reconfigurable between a first mode of operation and a second mode of operation, wherein the high pressure pump is configured to provide a fluid output to the at least one of the turret and the hose reel during the first mode of operation, and wherein the low pressure pump is configured to provide a fluid output to the low pressure discharge during the second mode of operation. - View Dependent Claims (15, 16, 17, 18, 19)

20. A vehicle, comprising:
-
a frame; an engine coupled to the frame; a fluid reservoir coupled to the frame and configured to store a fluid; a first pump coupled to the fluid reservoir and configured to pump the fluid therefrom at a first pressure; a second pump coupled to the first pump, the second pump selectively driven by the engine to increase the pressure of the fluid from the first pressure to a second pressure; and a plurality of fluid discharges including (i) a structural discharge coupled to the first pump and (ii) at least one of a hose reel and a turret coupled to the second pump; wherein the second pump is configured to provide the fluid at the second pressure to the at least one of the turret and the hose reel during a first mode of operation; and wherein the first pump is configured to provide the fluid at the first pressure to the structural discharge during a second mode of operation.
