Abstract
PURPOSE: To increase the setting and stopping pressures of a pump and make it possible to operate the pump up to a small quantity of water by providing a throttle pressure detection switch in a water feed route, in a water feeding device for feeding water to a pressure tank by automatic starting and stopping of the pump.
CONSTITUTION: The pressure within a pressure tank 4 increases with the reduction in the quantity of water used, and the quantity of water passing a throttle 5 decreases. At this time, a contact PS-2 of a pressure difference detection switch 7 is opened by the difference between pressures before and after the throttle 5 at the exhaustion side of a pump 1, and actuation of a driving switch M of the pump 1 is released, and the pump 1 comes to a stop. In this manner, since the pump 1 detects the difference between pressures before and after the throttle 5 and sets the stop pressure highly to stop the pump 1, no change is introduced in the water feed quantity upon stopping the pump 1 even when the characteristic of the pump is deteriorated.
