ROTARY COMPRESSOR IN WHICH ROTARY VALVE IS INSTALLED WITH AT LEAST ONE SUCTION PORT FOR SUCTION OF A REFRIGERANT FOR COMPRESSING THE REFRIGERANT OF DIFFERENT QUANTITY BY EACH MODE

摘要

PURPOSE: A rotary compressor is provided to enable operation for different compression capacities and to execute exact working of components related to conversion into an operation mode by each compression capacity. CONSTITUTION: A rotary compressor comprises a cylinder part constituting a compression chamber and having a vane for partition of a compression space and a suction space; an upper bearing and a lower bearing(220) closing up the compression chamber; a crankshaft installed through the cylinder and the upper and lower bearings; at least one discharge port through which a compressed refrigerant is discharged; a rotary valve(820) rotatably installed with at least one suction port(710) for suction of a refrigerant, to compress the refrigerant of different quantity by each mode; and a contact part(900) rotating by the crankshaft. The upper and lower bearings are each arranged to the upper and lower sides of the cylinder part. The crankshaft has an eccentric part(310) rotating in an eccentric state. The discharge port communicates with the inside of the compression chamber. The contact part is arranged near the rotary valve, to provide additional rotating force to the rotary valve.
