Abstract
619,171. Treating charge. BEST, D. M. C., and CLERK, R. C. Nov. 23, 1946, Nos. 34820/46 and 9746/47. [Class 7 (ii)] A device for feeding lubricating oil to the induction pipe comprises a chamber 19, Fig. 2, filled slowly from a reservoir 17 through a tube 1b containing a porous plug 21, and emptied at starting through a pipe 2 leading to the induction pipe, means being provided to prevent the flow of oil either into the chamber 19 or through the pipe 2 after starting. A pipe 3 permits air to be drawn through the pipe 2 after chamber 19 is emptied, the air entering at 22 and flowing through an annular passage 1a to the top of chamber 17, thereby preventing oil flowing to chamber 19 until the engine stops, when it is refilled in about the time the engine takes to cool. A duct 5 containing a porous plug 25. and controlled by a needle valve 24 may permit a small amount of oil to flow to chamber 19 when the engine is running, e.g. in a new engine. The plugs 21, 25 may consist of felt, porous bronze, silicate, or other filter-like material. In one modification the air entering at 22 passes through a filter in the reservoir lid, and in another the pipe 2 contains a cock operated from a choke valve to close after starting, the pipe 3 connecting chamber 19 directly to atmosphere. In Fig. 5 oil under pressure from pump 42 enters a reservoir 17c and feeds the engine lubricating system through a pipe 43, a ball valve 45 shutting off communication with a chamber 19c connected to the induction pipe through a pipe 2. When the engine stops, the valve 45 opens and the chamber 19c, vented to atmosphere through a duct 50, fills slowly through a passage 1c and porous plug 21c. A duct 46 allows oil to escape if the valve 45 fails to close when the engine is running. In Fig. 6 the device is integral with the engine sump 17D, a pipe 1D being connected to the throat of a venturi 53 in the inlet pipe of the oil pump. When running, the suction prevents oil flowing to the chamber 19D connected to the induction pipe.
