DISCHARGE PORT OF ROTARY COMPRESSOR

摘要

PURPOSE: A discharge port of a rotary compressor is provided to reduce a compression loss due to re-expansion by reducing the dead volume of the discharge port. CONSTITUTION: A discharge port(18) of a rotary compressor comprises the discharge port installed to the upper side of a main bearing(7), to discharge compressed gas compressed from a cylinder; a valve(14) one end of which is a fixed end fixed to the main bearing and the other is opened and shut to the discharge port; and a retainer(17). The main bearing is inclined from the fixed end side toward the free end of the retainer. The discharge port is inclined at a predetermined angle in an inclined direction, in which the volume of the main bearing is decreased.
