ABSTRACT:
In a vehicle steam engine having a steam generating unit, a condenser, fluid pumps for supplying the condensed liquid and fuel to the steam generating unit, a plurality of bypass passages are connected between the input and output sides of each pump. An electromagnetic on-off valve is provided in each bypass passage. Sensors are connected to the steam generating unit to detect variations in temperature and pressure of the steam to provide corresponding electrical signals. Each of the sensed signals is compared with different critical levels to produce output signals at one of two discrete levels to open the bypass passages in stages to thereby regulate the flow rate of the fluid to the steam generating unit.
