Abstract

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

The invention claimed is:

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, the reed valve having a first surface facing the discharge port and a second surface opposite to the first surface;
a valve stop disposed in the fixed scroll and configured to restrict a lift amount of the reed valve; the valve stop being disposed on a second surface side of the reed valve, and
a ventilation hole disposed in the valve stop,
wherein the valve stop includes a portion not overlapping with the reed valve in a planar view of the fixed scroll, and
the ventilation hole is disposed in the portion not overlapping with the reed valve.

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.

5. The compressor according to claim 1 , wherein
a distance between the ventilation hole and the discharge port is equal to or less than 10 mm.

6. The compressor according to claim 1 , wherein
the ventilation hole has a slot shape.
