Abstract
The utility model discloses a suction port assembly of a piston compressor cylinder. The suction port assembly comprises a suction port communicated with the piston compressor cylinder, and further comprises a gas buffering chamber communicated with the suction port. Due to the arrangement of the gas buffering chamber communicated with the suction port, when refrigerant gas reaches the suction port, a part of the refrigerant gas flows to the gas buffering chamber communicated with the suction port and the refrigerant gas subjected to buffering returns along an original path; the speed of the refrigerant gas returning from the gas buffering chamber is obviously lower than that of the unbuffered refrigerant gas, so that after the refrigerant gas returning from the gas buffering chamber is mixed with the refrigerant gas entering the cylinder, the speed of the refrigerant gas passing by the suction port can be obviously reduced, while after the speed of the refrigerant gas is reduced, noises passing by the suction port can be obviously reduced and thus the noises of a compressor are controlled within a standard range. The utility model further discloses a piston compressor with the suction port assembly.

Embodiment
Core of the present utility model is to provide a kind of intakeport assembly of piston compressor cylinder, to reduce the noise of refrigerant gas when through intakeport, thereby reduces the noise of compressor.
Another core of the present utility model is to provide a kind of compressor with above-mentioned intakeport assembly.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the part exploded perspective view that Fig. 1 is the suction side that provides in the utility model embodiment, the master that Fig. 2 removes after cylinder head for the suction side providing in the utility model embodiment looks schematic diagram.
The intakeport assembly providing in the present embodiment specifically comprises the intakeport 7 communicating with piston compressor cylinder and is connected with intakeport 7 and gas buffer chamber 10 for refrigerant gas is cushioned.
Owing to being provided with the gas buffer chamber 10 communicating with intakeport 7, thereby in the time that refrigerant gas arrives intakeport 7 position, part of refrigerant gas can flow to the gas buffer chamber 10 communicating with intakeport 7, and gas is through will returning on former road after buffering, in return course, will mix with the gas that is inhaled into cylinder from intakeport 7, because the refrigerant gas returning from gas buffer chamber 10 is with respect to the refrigerant gas without buffering, its speed significantly reduces, after mixing with the refrigerant gas that enters cylinder, can significantly reduce the speed through the refrigerant gas at intakeport 7 places, and after refrigerant gas Speed Reduction, noise during through intakeport 7 will significantly reduce.
As can be seen here, the intakeport assembly of the piston compressor cylinder providing in above-described embodiment can effectively reduce the noise of refrigerant gas when through intakeport 7, thereby the noise that whole compressor is produced obviously reduces, by the noise control of compressor in critical field.
