Rotary fluid flow machines

摘要: A ROTARY FLUID FLOW MACHINE COMPRISING BODY, AN AXIAL MEMBER OR SHAFT ROTATABLE RELATIVE TO THE AND GENERALLY ANNULAR MOUNTED FOR RECIPROCATION ROTATION IN CAVITY DEFINED BETWEEN BODY SHAFT. ARE RELATIVELY ROTATABLE, IS PROVIDED WITH UNDULATING END SURFACES. BY SPACED CONCENTRIC INNER OUTER CYLINDRICAL SURFACES PAIR OF AXIALLY CONFIGURATION, EACH COOPERATING SEPARATE ONE MEMBER, WHEREBY ANNNULAR CONSTRAINED ENGAGEMENT TWO MOVEMENT TYPE INVOLVING FIRST ROTATIONAL COMPONENT MOTION SECOND RECIPROCATORY COMPONENT. SURFACES, PLURALITY CHAMBERS DEFINED, VOLUMES WHICH UNDERGO CYCLIC VARIATION WHEN UNDERGOES SUCH MOVEMENT. AFFIXED SLEEVE DEFINES EXTENSIONS EITHER SIDE THEREOF, SLIDINGLY ENGAGING SURFACE MEMBER. PORTS ROOT PORTIONS ON TRANSVERSE EDGES OFTHE EXTENSIONS, COMMUNICATION RESPECTIVE CONTROLLED DURING RECIPROCATING THEREOF.
