Abstract

The blower/ignition/electrical system supplies the air, spark, and electrical power to facilitate and control the fuel combustion in a heat exchanger for devices which output a fluid, such as a pressure washer. The system is belt driven as an intricate part of the mechanical power system used for the fluid pressure pump. The flange/magnet hub spins past the ignition coil which in turn produces a high voltage electrical source. This potential is applied across the electrode gap to ignite a fuel. The flange magnet hub also spins past a stator coil assembly which in turn produces an alternating current. This current can be rectified or left unrectified, and is wired to a switch. When the switch is activated, the current path is through the safety control devices (such as temperature control, pressure switch or flow switch) and the fuel solenoid valve which controls the fuel flow into the combustion chamber. With the air, ignition spark, and fuel supplied and controlled in the combustion chamber, fuel combustion can now occur.
