Flame-thrower for fireworks display

摘要

The flame-thrower has a high pressure pump which atomises a fuel and an igniter to produce sparks for initiating the flame. The igniter can be a grinding wheel driven by a pneumatic motor engaged by a piece of metal. The igniter is mounted adjacent the outlet of the fuel pump. The piece of metal can be driven by a pneumatic motor against the grinding wheel. The pump can be controlled by an electro-valve.
