Abstract
Abstract In generator apparatus for the combined production of electrical energy and heat, of the type comprising a support casing housing an internal combustion engine with an air filter the inlet of which communicates with an aperture in a side wall of the casing, an electrical machine coupled to the engine, and electronic circuits for controlling the operation of the engine and the electrical machine, a covering and protecting element is fixable sealingly and removably to the outer surface of the side wall of the casing to define a region between the element and the wall. The electronic circuits are supported by at least one plate fixed to the outer surface of the side wall in the region between the wall and the covering and protecting element, and the element has at least one aperture through which this region communicates with the exterior. In operation of the apparatus, the electronic circuits are ventilated by air which is drawn in by the engine and flows into the region through said at least one aperture.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
275 words
A generator apparatus for the combined production of electrical energy and heat comprising a parallelepiped-shaped housing, a combination internal combustion engine and electrical machine mounted in said housing, said housing having a side wall provided with first and second apertures adjacent one vertical edge thereof with said first aperture located above said second aperture, duct means in said housing communicating said first aperture with said internal combustion engine for supplying air thereto with said electrical machine extending outwardly of said housing through said second aperture, a battery mounted on said side wall outside of said housing in spaced relation to said aperture, electrical equipment means mounted on said side wall adjacent the opposite vertical edge thereof, a cover member in the form of a substantially parallelepiped box open at one side thereof hinged to one of said vertical side edges of said housing covering said electrical machine, said battery and said electrical equipment means when pivoted against said side wall, a partition in said cover member adapted to engage said side wall in the closed position for dividing said cover member into a first chamber which completely encloses said electrical machine and a second chamber which completely encloses said electrical equipment means and said battery with said first and second chambers being isolated from each other, and opening means in said cover member adjacent the bottom thereof whereby upon operation of said internal combustion engine, air will be drawn into said cover member through said opening means and pass over said electrical equipment means and said battery before being drawn into said internal combustion engine through said first aperture and duct means as preheated air.
