Abstract

PURPOSE:To make a vane pump suitable for pumping sewage by causing negative pressure in a spiral casing to draw water to generate the negative pressure in a water guide port, and making this negative pressure draw the water and flow it in through a vacuum valve. CONSTITUTION:Water is drawn by negative pressure in a spiral chamber 7 to cause the negative pressure in a water guide port 5 to generate the negative pressure in a pipe 3, and is thereby drawn into a spiral chamber 7. The water is forcedly fed toward a discharge port 11 to subject a vacuum valve 10 to the negative pressure, and when the negative pressure behind the vacuum valve 10 becomes lower than that before the valve 10, the vacuum valve 10 opens to make the water flow in from the side of a suction port. The centrifugal force of the flowing water makes foreign matter in the pipe 3 flow along its outside inner wall, and the foreign matter thereby can flow through the pipe 3 without being drawn into water guide port 4 to get out of a pump.
