Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A bonnet structure for a generator including an engine for driving the generator, a radiator having guide means for supplying water therein, and a muffler having an exhaust nozzle means mounted thereon, said generator having a rotor-fan for air intake wherein said bonnet structure comprises a main wall for enclosing the engine and the generator, said main wall having a first air intake means for cooling the engine, a second air intake means for cooling the generator and an outlet means, a partition wall provided within said main wall so as to define first and second chambers, said first chamber enclosing the engine and said second chamber enclosing the generator, the rotor-fan of said generator being located within said first chamber enclosing the engine, a sound absorption plate means covering the entire inner walls of said first chamber and a cover wall for covering said muffler wherein cooling air introduced through said second air intake means flows inside of said second chamber before it joins cooling air introduced through said first air intake means.
