Guest Posted December 28, 2002 Share Posted December 28, 2002 I was reading through a book entitled "Krausz's ABC of Motoring" (1906), where the term "valve cage" (of the engine) was used. What is a valve cage? Link to comment Share on other sites More sharing options...
1937hd45 Posted December 28, 2002 Share Posted December 28, 2002 Good to know that you're into the older cars! A valve cage was an early design that was a removeable unit, valve, spring and seat. Try to picture a BIG sparkplug about two inches wide at the threaded portion, the valve would be in the same location as the porcelain insulator, with a spring and keeper. This unit could be removed to grind the valve seat in an early T head engine. If you can find a copy of Dykes Automobile Encyclopedia there are some great illustrations of this valve design. This design is still used in some diesel engines today. Link to comment Share on other sites More sharing options...
Guest Posted December 29, 2002 Share Posted December 29, 2002 Thank you for your response! This morning I located the only A.L.Dyke publication I have, The Diseases and Cures of a Gasoline Automobile and How to Cure Them (Revised edition-1908), which does not have the illustrations you mention. However, your description is very complete and understandable. Thanks again. Link to comment Share on other sites More sharing options...
Guest Posted January 2, 2003 Share Posted January 2, 2003 The later (WW-I era) Dykes Encyclopedias mention them.I think Buicks used caged valves, pre-'20s.Some early motorcycle engines also employed this technology.They had pretty much disappeared from passenger cars by 1925 or so.De Soto Frank Link to comment Share on other sites More sharing options...
D Binger Posted January 3, 2003 Share Posted January 3, 2003 I own a 14 and a 22 Buick and both have cage valves. They work fine.Dan Link to comment Share on other sites More sharing options...
Mrbuick714 Posted January 9, 2003 Share Posted January 9, 2003 My 1923 Buick had caged valves.You could take a large spanner and out came valve,seat spring and all. You could grind the valves without draining the coolant.Neat! Link to comment Share on other sites More sharing options...
