Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and in particular to an integrated refrigeration compressor limiter. Background Art

[0002] The compression mechanism of the compressor usually uses a valve assembly for exhaust. Since the valve assembly structure has a periodic exhaust feature, its exhaust valve plate will periodically hit the limiter, exciting the limiter to produce large vibrations, which are then transmitted to the shell and other structures to radiate noise outward. The noise generated by the operation of the compressor is too great for the refrigerator or air conditioner refrigeration operation. The instantaneous impact speed and impact intensity of the valve plate hitting the limiter are too large, which affects the reliability of the valve plate and the limiter, and causes a significant increase in the impact mechanical noise, resulting in an increase in the operating noise of the compressor and the refrigerator. Utility Model Content

[0003] The purpose of the utility model is to provide an integrated refrigeration compressor limiter to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model is implemented by the following technical means:

[0005] An integrated refrigeration compressor limiter includes a connecting section, a buffer section, and a vibration-damping section that are sequentially matched and connected. The connecting section is matched and connected to an exhaust valve seat. The buffer section extends along the connecting section and bends upward. A buffer member is provided at the middle position of the buffer section. The bottom surface of the buffer member is provided in a convex arc shape. The thickness of the vibration-damping section decreases sequentially along the buffer section toward the vibration-damping section. A damping material that matches the vibration-damping section is bonded to the vibration-damping section.

[0006] Furthermore, a first buffer groove and a second buffer groove are respectively provided on the lower surface and the inner side surface at the middle position of the buffer section, a mounting hole connecting the first buffer groove and the second buffer groove is provided in the middle of the buffer section, and a buffer component cooperating with the first buffer groove, the second buffer groove and the mounting hole is installed in the middle of the buffer section.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] When the utility model is in use, when the exhaust gas in the compressor impacts the exhaust valve plate and hits the limiter, the exhaust valve plate first contacts the arc-shaped bottom surface of the buffer component, and the buffer component is squeezed toward the buffer section of the limiter by the hitting, which can buffer the hitting force of the exhaust valve plate and reduce the hitting energy. The buffer section vibrates after being hit, and the vibration section of the limiter is composed of arc sections with radius successively increasing along the buffer section toward the vibration reduction section, which can attenuate the energy of the wave. At the same time, in combination with the damping material, the mechanical vibration of the vibration section can be converted into heat energy and dissipated, further consuming the energy of the wave and improving the vibration reduction and noise reduction effect.

Referring to the accompanying drawings, the buffer segment 2 is curved, and the lower surface and the inner side surface of the middle position of the buffer segment 2 are respectively provided with a first buffer groove 21 and a second buffer groove 22 for cooperating with the buffer member 4. In order to realize the installation of the buffer member 4 on the buffer segment 2, the middle part of the buffer segment 2 is also provided with a mounting hole 23 connecting the first buffer groove 21 and the second buffer groove 22.

The upper surface of the buffer elastic member 42 is not connected to the inner surface of the first buffer groove 22 and the two ends are rounded, so that there is a gap between the buffer elastic member 42 and the first buffer groove 22, thereby improving the ability to disperse the impact of the exhaust valve plate, improving the buffering shock absorption effect, and improving the noise reduction effect.
