ABSTRACT:
In regulating a burning gas quantity of a gas combustion apparatus, a gas flow controller is used. The gas flow controller is constructed such that a closing member within a cock is rotated by using a motor. The closing member has a plurality of holes formed in the axial direction of the member and a plurality of grooves each corresponding to the hole and formed in the circumferential direction of the member. The cock is used for changing, opening and closing a plurality of orifice passageways. The motor is driven in accordance with a signal from a position determining unit which discriminates the position of the cock. The gas flow controller can advantageously ensure a high precision of gas flow, a high reduction ratio, and a low power consumption.
