Problems solved by technology

During the reciprocating operation of the compressor, since the tongue reed in the suction valve plate is just located within the range of the cylinder bore of the cylinder block, when the compressor inhales air, the reed swings toward the cylinder bore under the action of the airflow pressure to open the suction port , but because the reed has no stop when it is inhaled and swings, the degree of freedom is high, and the reed swings at a frequency of 3,000 times per minute. increased noise

Abstract

The invention relates to the field of compressors, and discloses a suction and exhaust device used for a compressor and the compressor. The suction and exhaust device comprises an air cylinder body (1) and an air suction valve sheet (2), a cylinder hole (11) is limited in the air cylinder body (1), the air suction valve sheet (2) is arranged on a cylinder face (12), located on one end of the cylinder hole (11), of the air cylinder body (1) in parallel, the air suction valve sheet (2) is provided with a tongue spring (21) capable of swinging towards the cylinder hole (11), the air suction and exhaust device comprises a limiting part (22) on the tongue spring (21) and a limiting groove (13) formed in the cylinder face (12), the limiting groove (13) is arranged to be matched with the limitingpart (22) to limit swing of the tongue spring (21) towards the cylinder hole (11), and a buffer pad or damping coating is arranged in the limiting groove. The air suction and exhaust device can effectively reduce the noise generated by the tongue spring of the air suction valve sheet in the air suction process.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a suction and discharge device for a compressor and a compressor including the suction and discharge device. Background technique [0002] Existing hermetic reciprocating piston compressors usually include a crankcase, a cylinder block arranged on the crankcase, a cylinder head covered on the cylinder block, and a suction and exhaust valve assembly arranged between the cylinder block and the cylinder head . Wherein, the intake and exhaust valve assembly includes an exhaust valve plate disposed close to the cylinder head and an intake valve plate disposed close to the cylinder body. During the reciprocating operation of the compressor, since the tongue reed in the suction valve plate is just located within the range of the cylinder bore of the cylinder block, when the compressor inhales air, the reed swings toward the cylinder bore under the action of the airflow pressure to open the s...
