Rotary compressor

Abstract

Abstract PURPOSE:To prevent decrease in efficiency, by providing a check valve at inlet portion and providing an discharge valve at an discharge portion as well as a control valve at a discharge pipe entering portion which opens in a muffler forming a semi-airtight space. CONSTITUTION:A discharge pipe 11 has one end opening in a muffler 14 through a bearing 16 of a compression element 8 and has the other end connected to a circuit at the outside of a closed case 7. There is provided an open/close control valve 3 in the vicinity of an opening hole 17. A check valve is provided at an inlet portion. When a compressor stops, the internal pressure of the muffler 13 balances with the pressure in the closed case 7, the valve 3 is closed, a gas flow to a unit is shut off and heat is restricted to enter into an evaporator, whereby decrease in efficiency is prevented.
