Abstract
Official abstract text for this publication.
A compressor includes: a fixed scroll; at least one discharge port; a reed valve; a valve stop; and a ventilation hole. The at least one discharge port is disposed in the fixed scroll. The reed valve is disposed in the fixed scroll so as to block the at least one discharge port. The valve stop is disposed in the fixed scroll, and restricts the lift amount of the reed valve. The ventilation hole is disposed in the valve stop. In the present aspect, the flow of refrigerant gas is smoothed to suppress the compression loss, and the force applied to the reed valve can be suppressed. As a result, the efficiency and reliability can be improved.
First claim
Opening claim text (preview).
1 . A compressor comprising: a fixed scroll; a discharge port disposed in the fixed scroll; a reed valve disposed in the fixed scroll and opening and closing the discharge port; a valve stop disposed in the fixed scroll and configured to restrict a lift amount of the reed valve; and a ventilation hole disposed in the valve stop. 2 . The compressor according to claim 1 , wherein a plurality of discharge ports are disposed in the fixed scroll, each of the plurality of discharge ports being the discharge port, and the ventilation hole is disposed between two adjacent discharge ports, of the plurality of discharge ports. 3 . The compressor according to claim 1 , wherein the ventilation hole is disposed in a part of the valve stop, the part not coming into contact with the reed valve. 4 . The compressor according to claim 1 , wherein the ventilation hole is disposed in parallel with the reed valve.
