AXIAL VANE ROTARY ENGINE WITH ROUNDED VANES

摘要

An axial vane rotary engine has a housing with spaced-apart sides and a peripheral wall defining a cylindrical interior chamber. A rotor is rotatably mounted within the interior chamber of the housing. There is an annular cam surface on at least one of the sides of the housing within the interior chamber and axially spaced-apart from the rotor. A plurality of angularly spaced-apart, axially extending slots are formed in the rotor. An axially slidable vane is received in each of the slots. Each vane has an outer portion sealingly engaging the cam surface and forming fluid receiving and pressurizing spaces between adjacent said vanes. The cam surface has a plurality of alternating high cam portions and low cam portions. The high cam portions and the low cam portions are spaced-apart from the rotor and the high cam portions are closer to the rotor than the low cam portions. The vanes extend further from the rotor in the low cam portions compared to the high cam portions so the fluid receiving spaces are compressed when adjacent the high cam portions compared to positions adjacent the low cam portions. There is an air intake means for intaking air into the spaces, a fuel intake means for intaking fuel into the spaces. There is a spark plug for igniting an air/fuel mixture in the spaces and an exhaust for exhausting exhaust gases from the spaces.
