Abstract:
A rotary vane engine, comprising:a housing formed by a stator and a front and rear covers, said housing enclosing an inner space;a rotor having four radially extending slots divided into equal parts circumferentially rotatably mounted within said inner space with same main axis of said housing, each of said slots receiving a radially slidable vane, each vane having a sealing end contacted to the wall of said inner space and two retention ends with the bearings guided in guide tracks individually;said wall of said inner space being made up of two pairs of arc-shaped walls which are placed opposite each other with respect to the main axis and together with the periphery wall of said rotor, both sides of the vanes and the front and rear covers forming two pairs of symmetric intake-compression chambers and power-exhaust chambers respectively;a pair of inlets formed in said stator, said pair of inlets being positioned at the beginnings of said intake-compression chambers and passing through the wall of said stator respectively symmetrically with respect to the main axis;a pair of outlets formed in said stator, said outlets being positioned at the ends of said power-exhaust chambers and passing through the wall of said stator respectively symmetrically with respect to the main axis;a pair of symmetric cylinders with respect to the main axis formed in the upper and lower ends of said stator respectively;a pair of combustors, each of said combustors consisting of two separated combustion chambers and rotatably mounted within said cylinders respectively;a compressed gas channel formed between each of said cylinders and adjacent end of the intake-compression chamber substantially tangential to the cylinder;a combustion gas nozzle formed between each of said cylinders and adjacent beginning of the power-exhaust chamber;a spark hole formed in the wall of each of said cylinders with a certain circumferential distance from said combustion gas nozzle at the side of the power-exhaust chamber;a fuel injector mounted in the wall of each of said cylinders adjacent and roughly opposite to said compressed gas channel at the side of the intake-compression chamber;a spark plug installed in each said spark hole;means for guiding the vanes; anda lubricating system, and a cooling system;whereby said rotor is a hollow one; andwhereby the volume of each of said power-exhaust chambers is larger than the volume of each said intake-compression chambers.
