Abstract

A gear wheel driver displacement pump has one of the gear rims as the cross-bars carrier and this rim is statically mounted, whereas the intermediate gear wheels are mounted such that they can ride on the static gear rim in order to set the other gear rim in motion. The rotation of this rim is transmitted to the working shaft of the pump. The bevel gear serves as the drive component with the external toothed gear rim. The surface of each cross-bar to which is attached an intermediate gear wheel is of cylindrical section of radius similar to that of the external diameter of the intermediate wheel such that the hermitic chambers only receive a minimal corrosive material volume.
