Abstract

The invention provides a lift limiter, a valve group, a reciprocating compressor and refrigeration equipment. The lift limiter comprises an abutting end face, the abutting end face is used for being matched with an exhaust valve plate of the reciprocating compressor in an abutting mode, the lift limiter is provided with at least one airflow channel, and the airflow channel penetrates through the abutting end face. In the using process, airflow can be blown to the exhaust valve plate through the airflow channel, so that the low-pressure area on the back face of the exhaust valve plate is reduced or disappears, the adhesive force of oil possibly left on the abutting end face to the exhaust valve plate is reduced, the exhaust valve plate is closed more smoothly, the risk of closing delay of the exhaust valve plate is reduced, and the service life of the exhaust valve plate is prolonged. And the performance of the reciprocating compressor is improved. And meanwhile, the refrigerant can pass through the airflow channel, so that the exhaust resistance of the reciprocating compressor is reduced, and the energy efficiency ratio of the reciprocating compressor is improved. In addition, the airflow channel can also play a role of a resonance chamber, so that the noise generated when the exhaust valve plate claps the lift limiter is reduced.
