Abstract

832,144. Carburetters. BROWN ENGINE PRODUCTS Inc. June 6, 1958 [May 7, 1958], No. 18222/58. Class 7(3) In a carburetter having a body structure defining a fuel passage for conducting liquid fuel from a fuel source pressurized by a flexible diaphragm pump means 25 through a first needle valve 34 to a fuel reservoir 35 and from the fuel reservoir through a second needle valve 55 to a Venturi charge forming chamber 54, the carburetter body structure is formed with a fuel well 65 in the fuel passage immediately upstream from the first needle valve to provide a reserve of fuel for acceleration and to serve as a pressure surge compensation chamber. The body structure 10 permits the idling jet orifices 52 and 53 to communicate with the chamber 51 at either one of two fuel delivery positions. Also the design permits the shaft 62 of the throttle butterfly valve 61 to be disposed either horizontally or vertically. As shown the diaphragm pump is worked by crank case pressure communicated to the chamber 28. From the reservoir 35 the fuel exits through a passage 45 into a tubular filtering element 46. Thence the fuel may flow either through an idling passage 47 or a main outlet passage 47<SP>1</SP>. Flow through the idling passage 47 into an auxiliary chamber 48 may be selectively con-trolled by an idle adjustment needle valve 49. The auxiliary chamber 48 is separated from the reservoir 35 by a removable plug 50. The fuel passes from the auxiliary chamber 48 into a charge forming chamber 51 through either a primary idling jet orifice 52 or a secondary idling jet orifice 53. The charge forming chamber 51 is at the outlet end of a Venturi 54. Flow of fuel from the reservoir 35 through the main outlet passage 47' is controlled by a high speed adjustment needle valve 55. Fuel passing this needle valve enters a high speed jet chamber 56 (which is closed from the fuel reservoir by a plug 57) and passes into the throat of the Venturi 54 through a high speed jet orifice 58. A cylindrical plug of felt may be inserted in the well 70 rather than the tubular element shown. The space below the diaphragm 42 comunicates with the atmosphere.
