Abstract

An intake charged pump for pumping liquid and which has an intake duct that extends to the suction area of the pump. The pump has a duct through which a jet stream flows to the suction area. A nozzle arrangement in the intake duct accelerates the liquid which is returned via the jet stream and supports the suction of a suction stream of the liquid from a storage container. A nozzle of the nozzle arrangement leads into the mixing chamber at an acute angle in a such way that the jet stream, leaving the nozzle, creates a common mixing stream with the suction stream from the storage container, and through which partial streams having essentially the same pressure and energy content, can be delivered to the front and back suction pockets of the double chamber pump.
