Abstract
A liquid immersible scroll pump in which all of the pump components including electric motor drive means are contained within a housing and through which the liquid is pumped at a controlled predetermined pressure. Hydraulic pressure within the pump provides sufficient axial force on the scroll members to enhance radial sealing as well as the tangential sealing of the flanks of the scroll wraps. The pump is particularly suited for low-cost mass production and may be used as a fuel pump, either immersed in the fuel tank of an automobile or mounted outside the tank, to provide fuel under pressure through a line to the engine.
