Rotary type valve plate compressor

A rotary type valve plate compressor, comprising;

• a shaft;
• a housing surrounding the shaft;
• a plurality of cylinders mounted in the housing;
• a piston received in a corresponding cylinder of the plurality of cylinders and configured to be moved forward and rearward in response to rotational operation of a swash plate;
• and
• a rotary type valve plate configured to receive a rotational force of the shaft and formed with a plurality of refrigerant passage holes through which refrigerant passes, wherein refrigerant passage holes of the plurality of refrigerant passage holes are selectively open or closed based on a phase of the piston;
• a hole guide coupled to one side of the rotary type valve plate;
• and
• an end cover coupled to one side of the hole guide,
• wherein the refrigerant passage holes comprise:
• a low-temperature low-pressure gas-suctioning hole through which low-temperature low-pressure gas is sucked, and a high-temperature high-pressure gas-discharging hole through which high-temperature high-pressure gas is discharged,
• wherein the high-temperature high-pressure gas-discharging hole is disposed at a different radial position from the low-temperature low-pressure gas-suctioning hole,
• wherein a radius of curvature of the low-temperature low-pressure gas-suctioning hole is smaller than a radius of curvature of the high-temperature high-pressure gas-discharging hole,
• wherein:
• the hole guide includes a plurality of refrigerant-flowing holes formed at regular intervals at different radial positions which are opened and closed by the rotary type valve plate, and
• the plurality of refrigerant-flowing holes includes:
• outer refrigerant-flowing holes configured to communicate with the low-temperature low-pressure gas-suctioning hole, and inner refrigerant-flowing holes configured to communicate with the high-temperature high-pressure gas-suctioning hole.
