Definitions

  • This invention comprises certain improvements in or relating to carburetors for internal combustion engines and it refers to the type of carburetor wherein provision is incorporated for regulating the ingress of fuel by or in accordance with the movements of the throttle valve. It is one of the objects of the present invention to provide for an effectual process of fuel delivery in circumstances in which in a carburetor of this type the throttle valve is opened in a substantial degree by a quick movement. We attain this object by making provision for forced delivery of the fuel in circumstances in which the action of quick opening occurs.
  • Figure 2 illustrates a modified embodiment of the present invention.
  • a jet 6 adapted to deliver into a chamber or cylinder which extends upwardly to a point above the normal liquid fuel level in the supply.
  • the fuel is adapted to be admitted to the main draught passage 0 of the carburetor by an opening which is controlled by a taper needle d projecting downwardly into the vertical chamber or cylinder.
  • This needle may be fixed to and adapted to move with a piston throttle valve moving vertically across the draught passage towards and away from the orifice which the taper member regulates.
  • the vertical cylinder I provide a piston 6 below which a coiled spring f is 1ncorporated to normally tend to press it upwardly against the lower extremity of the taper needle.
  • a coiled spring f is 1ncorporated to normally tend to press it upwardly against the lower extremity of the taper needle.
  • one or more perforations g is or are provided of a capacity or aggregate capacity equal to or exceeding the capacity of the primary jet.
  • the piston assumes a position below the normal liquid fuel level in the supply and normally the fuel is adapted to flow successively through the primary jet, the orifices or orifices in the piston and the delivery orifice controlled bythe taper needle. But if the taper needle is caused to ascend rapidly the piston ascends with it under the influence of the spring and impels the accumulated liquid fuel above said piston through the delivery orifice it into the draught passage.
  • the piston Upon the piston being brought to rest inits upward movement bv the taper needle normal conditions of supply resume.
  • a non-return valve i which for example may comprehend a ball valve providing for a free flow of liquid from the lower to the upper side of the piston while when the piston e operates in its function of impelling the excess fuel the non-return ball valve i is automatically closed so that the piston operates in manner similar to that obtaining in circumstances in which this non-return valve is not incorporated.
  • a liquid fuel well means to supply fuel thereto, a piston fitted in the well and having a restricted duct for the passage of fuel from the well, a needle valve hearing on the piston and arranged for movement together with the piston, a spring active to cause the piston to follow the needle valve when the latter is withdrawn and thus cause the piston to force fuel thereabove into the mixing element of the carburetor and a valve to close against return movement of fuel through the piston.
  • a liquid fuel well means to supply fuel thereto, a piston fitted in the well and having a restricted duct for the passage of fuel from the well, a throttle valve,
  • a needle valve carried thereby so as to bear on the piston and arranged for movement together with the piston and a spring active to cause the piston to follow the needle valve when the latter is Withdrawn and thus cause the piston to force fuel thereabove into the mixing element of the carburetor.
