Patent ID: 8276831

Claim:
A motor vehicle configured to provide an electrical power and a compressed air to a spray foam insulation system, comprising: a vehicle including a frame, a cab, a front engine compartment housing an engine which outputs rotary motion to a crankshaft, a drive shaft which propels wheels of the vehicle, a transmission which transmits rotary motion of the crankshaft to the drive shaft, and a truck box behind the cab configured for storing and carrying objects; an air compressor mounted in the front engine compartment and connected by a belt and pulley to the crankshaft, including a clutch and a first control system allowing the air compressor to be turned off and on while the engine is running; an air tank mounted on an exterior of the vehicle and connected to the air compressor, wherein the air tank provides the compressed air to the spray foam insulation system; a power take off connected to the transmission, including a secondary drive shaft and a second control system for engaging and disengaging the power take off; a closed-loop hydraulic generator system mounted on the exterior of the vehicle, wherein the closed-loop hydraulic generator system comprises a hydraulic pump connected to and operated by the secondary drive shaft, and a hydraulic motor connected to receive and be driven by a hydraulic fluid from the hydraulic pump; an electrical generator mounted on the exterior of the vehicle, and connected to receive and be driven by the hydraulic motor, wherein the electrical generator provides the electrical power to the spray foam insulation system; and a controller which receives input indicating electrical power demand on the generator and connected to an actuator on the hydraulic pump, including programmed parameters for operating the hydraulic pump to match flow pressure of the hydraulic pump to the electrical power demand on the generator.
