Patent number: 7124724Abstract: An air-cooled ignition lead for use with aircraft engines to conduct high voltage ignition pulses between an exciter and an igniter. The ignition lead includes a center conductor covered by an insulation jacket for electrical isolation. Radially spaced outwardly from the insulation jacket is a flexible conduit that has sufficient structural integrity to resist collapsing inwardly. The insulation jacket and conduit define an airflow path therebetween that is used for conducting air through the lead. An innerbraid is located over and supported by an outer surface of the flexible conduit, and this location of the innerbraid prevents it from collapsing over time and obstructing the airflow passage that extends on the inner side of the flexible conduit. The innerbraid can be used as a return path conductor that provides a return current path and/or EMI shielding. Covering the innerbraid is an outerbraid to protect the lead against external damage.Type: GrantFiled: February 15, 2005Date of Patent: October 24, 2006Assignee: Champion Aerospace, Inc.Inventor: Charles T.

Patent number: 7104252Abstract: A four-stroke combustion engine is lubricated by a mixture of lubricant, fuel and air received from a rotary valve type carburetor. A cylinder of the engine houses a reciprocating piston and together they generally define a combustion chamber segregated from a generally sealed cavity which contains a mechanism for operating intake and exhaust valves communicating with the combustion chamber. Generally non-burning lubricant along with fuel-and-air enters the combustion chamber from the rotary-type carburetor and blows-by the piston into the sealed cavity through a clearance defined generally between the cylinder and piston for cooling the engine and lubricating the mechanical linkage assembly. Preferably, the sealed cavity is vented directly into a rotary throttle valve of the carburetor for controlled flow back into the engine without use of a check valve, enhanced idling characteristics of the engine and substantially reduced spit-back through the carburetor air inlet.Type: GrantFiled: June 15, 2005Date of Patent: September 12, 2006Assignee: Walbro Engine Management, L.L.C.Inventor: George M.
