PURPOSE:To obtain a fuel volume controller of a combustion device, simple in structure, reliable in performance, stable in flow, excellent in durability and further steplessly proportionally controllable to the desired temperatures. CONSTITUTION:A control rod 10 supported and synchronized with the movement of an electromagnetic movable piece 15 between two springs 11, 19 closes the end of the orifice 2 of a nozzle by the end of the control rod. On one hand, using the pulse current which energizes an electromagnetic coil 24 and is controlled automatically or manually through a control circuit enabled to change and control the charging time per the cycle of the pulse current, the control rod 10 is reciprocated minutely at positions apart from the end of the orifice 2. In this manner, it is enabled to adjust the opening rate, change, and average the fluid friction in the space between the control rod and the orifice end, to increase stepless controlling ratio of discharging irrespectively of its quantity and to facilitate proportional control of temperature. |
