Abstract

A ROTARY COMPRESSOR INCLUDES A CYLINDER (5) HAVING A CYLINDER CHAMBER (51) TO WHICH A SUCTION PORT (52) AND A DISCHARGE PORT (53) ARE OPENED, A ROLLER (7) INSTALLED WITHIN THE CYLINDER CHAMBER (51) AND FITTED ON A ECCENTRIC PORTION (31) OF A DRIVE SHAFT (3) AND A BLADE (9) PARTITIONING THE INSIDE OF THE CYLINDER CHAMBER (51) INTO A LOW PRESSURE CHAMBER (X) COMMUNICATING TO THE SUCTION PORT (52) AND A HIGH PRESSURE CHAMBER (Y) COMMUNICATING TO THE DISCHARGE PORT (53). THE SUCTION PORT (52) IS FORMED SO AS TO BE INCLINED TOWARD THE BLADE (9) WITH RESPECT TO A NORMAL LINE (C) PERPENDICULAR TO A TANGENT AT A POSITION ON AN INNER CIRCUMFERENCE OF THE CYLINDER CHAMBER (51) WHERE THE SUCTION PORT (52) IS FORMED. WITH THIS CONFIGURATION, A FLOW RESISTANCE WHEN GASEOUS FLUID IS INTRODUCED FROM THE SUCTION PORT (52) TO THE LOW PRESSURE CHAMBER (X) OF THE CYLINDER CHAMBER (51) IS REDUCED AND ACCORDINGLY, PRESSURE LOSS OF SECTION GAS WITHIN THE LOW PRESSURE CHAMBER (X) CAN BE REDUCED.
