M The invention relates to `poppet valves and, in its most specic features, to what is commonly` called a tulip valv 1 a One object ofthe invention is tomake Mprovision? for "grinding" such valves "while avoidingconstructions which present sharp points or edges which-tend to cause preignition, especially `in high compression engines. .s
Another object of the invention is to pro-` the power of the engine. l
crease the `tendency to warpage in t tulip valves, and to provide a valve which will run cooler than those heretofore employed. j "'Ihe objects are attained by changing the i formation of the valve heads of prior constructions as will be hereinafter explained.
For the purpose of exemplifying the prini ciples of my invention, `I disclose herein f several embodiments of the invention, but l i which lind their best expression in the tulip i Valve shown inFigure l. j `5 "In the annexed drawings:
j Figure 1 is avertical section taken through i 3 a valve constructed in accordance with my a invention showingthe adjacent parts of the engine structure, this form being the one now preferred by me.` l i i .Figa2 is a top plan view of the valve. i a ,l Figi?,` is a vertical section,similar to Fig. l 1, of a modified form. j, j
Figs. 4 and 5 are fragmentary cross-sectional views through the upper edgelof tulip `valves constructed in accordance with the prior art." j i Fig. 6;shows the ordinary poppet valve having a curved dome, provided with a rey"sa vide a `tulip valve head which will increase Other objects of the invention are to decess in itsupper face having a reentrant` 192e. seriaiiro. 121,569;
`to 15 inclusive. my invention it is necessary to consider the action of exhaust gases g in the process of exhaustion by tulip valves of prior construction,` which such valves s has been either fiat, as indicated at a, Fig.
