发明名称 Constant pressure pressurizing water pump
摘要 A water pressurizing pump includes a pump mounted in a compartment of a water tank for pressurizing and outputting water. The compartment is sealed by a cover having a first channel in communication between the compartment and a water supply coupler and a second channel having an end in communication with the first channel. A pressure tank is mounted to the other end of the second channel of the cover. A differential pressure valve unit is slideably mounted in the pressure tank adjacent to the second channel. The differential pressure valve unit is movable by the high water pressure in the second channel to allow water from the second channel to enter the pressure tank.
