Abstract
PURPOSE: To prevent the chattering of pump by starting a pump with the working of pressure switch during the opening of water supply plug and stopping a pump with the working of thermister during the closing of the said plug.
CONSTITUTION: Bypass 8 is provided between the upstream-side and the downstream side of switch value which is forcibly opened by water pressure during the opening of water supply plug. In this bypass 8, pressure switch 11 and thermister 9 which control the starting and stopping of a pump are installed. If water supply plug 5 is opened, the pressure inside the bypass 8 is reduced, closing a contact point for pressure switch 11 and starting the pump 1. When the water supply plug 5 is squeezed, the water current becomes weak, allowing the switch valve 4 to be closed. However, with water running in the bypass 8, thermister 9 is cooled, permitting the continued driving of pump 1. Thus no chattering results. When the water supply plug 5 is closed, pump 1 is stopped by means of thermiter.
