Rotary compressor and refrigeration device

A rotary compressor comprising:

• a cylinder having a cylinder chamber therein;
• a piston configured to eccentrically rotate in the cylinder chamber;
• a drive shaft configured to drive the piston;
• a blade dividing the cylinder chamber into a suction-side space and a discharge-side space;
• a cylinder end plate closing an end portion of the cylinder in an axial direction thereof;
• and
• a reed valve having an elongated plate member on the cylinder end plate, wherein
• a discharge port communicating with the discharge-side space is formed in the cylinder end plate,
• the discharge port being formed such that as viewed in an axial direction of the drive shaft,
• part of an opening of the discharge port overlaps with an inside of the cylinder chamber, the elongated plate member of the reed valve closing the opening,
• an opening end face of the discharge port is inclined radially outward of the cylinder end plate such that a lowest point of the discharge port is at a radially outermost point thereof, and
• in a cross-sectional view orthogonal to a longitudinal direction of the plate member of the reed valve, an upper surface of the plate member is inclined toward a radially outward side of the cylinder end plate.
