Suction valve assembly for a compressor and a compressor having a suction valve assembly

A compressor, comprising:

• a casing;
• a refrigerant suction pipe, though which refrigerant is suctioned into the casing;
• a compression device including an orbiting scroll and fixed scroll configured to compress the refrigerant in a compression chamber formed therebetween;
• an accumulator having a refrigerant discharge pipe in communication with the refrigerant suction pipe;
• and
• a suction valve assembly, the suction valve assembly comprising:
• a horizontal pipe connected to the compression chamber via the refrigerant suction pipe and a vertical pipe connected vertically to the horizontal pipe, an end of the vertical pipe being connected to the accumulator via the refrigerant discharge pipe;
• a valve provided at a connection portion between the horizontal pipe and the vertical pipe, wherein during operation of the compressor, the valve is moved downward by weight so as to open the connection portion between the horizontal pipe and the vertical pipe and when the operation of the compressor stops, the valve is moved upward by a pressure difference between an inner space of the accumulator and an inner space of the compression chamber so as to close the connection portion between the horizontal pipe and the vertical pipe;
• and
• a protruding pipe provided under the vertical pipe of the connection portion between the horizontal pipe and the vertical pipe and protruding in a direction opposite to a direction in which the vertical pipe protrudes, an upper surface of the protruding pipe being open, at least a portion of the valve being positioned in the protruding pipe, wherein lifting and lowering movements of the valve are guided by the protruding pipe, wherein the valve comprises a cylindrical body, an upper surface of which is closed, at least a portion of a lower surface of which is open, and a circumferential surface of which includes one or more communicating holes provided thereon, each of the communicating holes communicating with an inner space of the horizontal pipe, and wherein the valve is configured to have a height such that a portion of an upper end thereof protrudes from the protruding pipe during a compression operation, wherein the one or more communicating holes are provided along a circumference of the upper end of the valve, and wherein during operation of the compressor, at least a portion of each of the communicating holes communicates with the inner space of the horizontal pipe.
