Bristol sleeve valve engines were used however during the post-war air transport boom, in the Vickers Viking and related military Varsity and Valetta, Airspeed Ambassador, used on BEA's European routes, and Handley Page Hermes (and related military Hastings), and Short Solent airliners and the Bristol Freighter and Superfreighter.
The Knight engine is an internal combustion engine, designed by American Charles Yale Knight (1868-1940), that uses sleeve valves instead of the more common poppet valve construction. These engines were manufactured in the large quantities in USA, Knight's design was made a commercial success by development in England, while the French ...
Known as the Bristol Orion, a name used previously for a variant of the Jupiter engine and later re-used for a turboprop, this development was also a two-row, 18 cylinder sleeve valve engine, with the displacement increased to 4,142 cu in (67,875.2 cm 3) [6.25 in × 7.5 in (159 mm × 191 mm)], nearly as large as the American Pratt & Whitney R ...

The Argyll aircraft engine was the first four stroke sleeve valve engine built for aircraft use. Manufactured by the Scottish car maker Argylls in 1914, the engine was a 120 hp straight-six design utilising Burt-McCollum single sleeve valves which eliminated the need for poppet valves .
In it, he wrote that traditional poppet valve engines would be unlikely to produce much more than 1,500 hp (1,100 kW), a figure that many companies were eyeing for next generation engines. To pass this limit, the sleeve valve would have to be used, to increase volumetric efficiency, as well as to decrease the engine's sensitivity to detonation ...

The Rolls-Royce Pennine was a British 46-litre air-cooled sleeve valve engine with 24 cylinders arranged in an X formation. It was an enlarged version of the 22-litre Exe; a prototype engine was built and tested, but never flew. [1] The project was terminated in 1945, being superseded by the jet engine. [2]
