patent statutes, I have described the princple of operation of my invention, to ther Wlth the apparatus which I now consi er to represent the -b'est embodiment thereof, but I desire 'to have it understood that the apparatus `shown is only illustrative and that the invention may be 4carried out by other means.
What I claim as new and desire to secure by Letters Patent of the United States, is:
LA pressure difference creating device of the Venturi tube type, comprising a plurality of comparatively short annular concentric Venturi tube members spaced radially from each other to provide a central venturi shaped passage surrounded by one or more annular venturi shaped passages, the throats of said tube members all lying in the same plane.
2. pressure difference creating device of the Venturi tube type comprising annular Walls which define a plurality of comparatively short, annular, concentric venturi shaped passages, the throats of said tube membersall lying inthe same plane.
weaves 3. The combination with a conduit n through which a liuid to be metered flows, of a pressure difference creating device in the conduit comprising Walls which define a plurality of comparatively short, annular.
concentric venturi shaped passages and means providing a conduit through which a pressure pipe may 'oe connected with a throat of at least one ofsaid passages.
4. A pressure difference creating` device of the Venturi tube type comprising a ring adapted to be fastened between adjacent pipe ends. and spaced concentric annular Walls located within and' carried by the ring which Walls define a plurality of concentric annular venturi shaped passages.
5. A. pressure difference creating device of the Venturi tube type, comprising Walls which define a plurality of comparatively short, annular, concentric venturi-shaped passages, the admission ends and the discharge ends of which lie in the same planes.
In Witness whereof, I have hereunto set
