Claim 2
Dependent Claim
46 words
An installation for feeding the electrical power supply of motor vehicles, which includes a generator means, a battery as accumulator means and several loads, characterized in that a thermionic converter means is provided as generator means, which is operable with the fuel of the motor vehicle.
Claim 3
Dependent Claim
31 words
An installation according to claim 1, characterized in that the thermionic converter means is designed for optimum efficiency at full power output and is operated only in the full load range.
Claim 4
Dependent Claim
17 words
An installation according to claim 2, characterized by control means for operating the thermionic converter means intermittently.
Claim 5
Dependent Claim
40 words
An installation according to claim 3, characterized in that said control means includes an automatic timing means for the intermittent operation in dependence on at least the power requirement in the power supply and the charge condition of the battery.
Claim 6
Dependent Claim
23 words
