Definitions

  • a check valve (not shown) may be incorporated within the supply line 25 to eliminate at least some of the cyclic fluctuations in pressure derived from the intake manifold 15.
  • the carburettor of this invention will be found to have most merit when applied to small I.C. engines such as used with lawn mowers, marine craft, portable power tools, and the like. Adjustment to the governed speed is preferably effected through effecting a change in tension of the upper spring 24 within the carburettor 10. It is now common practice on engines for the above purposes to provide only two speed conditions i.e. slow speed (or idling) and operating speed. Any one of the many presently available controls for effecting the change in tension may be incorporated.
  • Figs 3 and 4 show other conditions of the governed carburettor 10 firstly where the engine has reached its governed speed and is unloaded and secondly where the engine speed is falling from its governed speed and is unloaded. From the latter condition any further decrease in speed resulting from closing movement of the valve 16 will cause the diaphragm 28 of the device 26 to move downwardly and open the valve 31 thereby effecting consequential opening of the poppet valve 16 in the carburettor 10.
