摘要： A one-way clutch, including: a load rotor, a driving member, and at least one self-locking gripper. The load rotor is spool-shaped and includes two circular contact races, one race at each end of the rotor. The driving member includes a plurality of inward facing cams on an inner circumference arranged to rotate co-axially with the load rotor. The cams rotate within the space separating the two load rotor races. When in a locking position each gripper presses against both load rotor races and a cam over area-to-area contacting surfaces. Rotation of the load rotor and driving member are locked in the first direction when one or more grippers are in the locking position. The driving member is rotatable independent of the load rotor in the second, free-wheeling direction. During free-wheeling rotation centrifugal force acts to disengage the grippers from the load rotor, thus reducing or eliminating friction.

摘要： A multicylinder internal combustion free-piston engine (FPE) with synchronized reciprocating plungers. The invention provides a solution for the problem of the slow engine speed typical of FPE's with heavy plunger mass. Bounce chambers fitted with sleeve valves control the engine's speed and stroke length. The invention's configuration prevents piston head-strikes and operates at standard compression ratios. Piston “pop-top” intake valves allow uniflow scavenging and connecting rod oil channels provide lubrication with no combustion chamber contamination. Poppet combustion head valves are operated by linear cams attached to the plungers. Hydraulic valve actuators implement variable valve timing under computer control.
