Abstract

A two-stroke engine with valves near bottom dead center that are adapted to prevent intake charge from exiting exhaust ports, wherein the valves are actuated by air pressure difference.

IPC Classes  ?

• F02B 25/16 - Engines characterised by using fresh charge for scavenging cylinders using reverse-flow scavenging, e.g. with both inlet and outlet ports arranged near bottom of piston stroke the charge flowing upward essentially along cylinder wall opposite the inlet ports
• F02B 25/20 - Means for reducing the mixing of charge and combustion residues or for preventing escape of fresh charge through outlet ports, not provided for in, or of interest apart from, groups
• F02B 75/30 - Engines with two or more pistons reciprocating within same cylinder or within essentially coaxial cylinders with one working piston sliding inside another
• F02B 75/02 - Engines characterised by their cycles, e.g. six-stroke

Abstract

A turbine which uses fluid pressure to turn a shaft in a manner that does not allow for cavitation to be created.

IPC Classes  ?

• F03B 17/06 - Other machines or engines using liquid flow, e.g. of swinging-flap type
• F01D 7/00 - Rotors with blades adjustable in operationControl thereof
• F01D 15/12 - Combinations with mechanical gearing
