Compressor discharge assemblies and rotary compressors

Abstract

The present invention discloses an air discharging assembly of a compressor, and a rotation type compressor. The air discharging assembly of the compressor comprises a bearing, a silencer, a high-low pressure separation plate, and an oil distribution structure, wherein the silencer is arranged on the bearing and defines a first air discharging cavity together with the bearing; the high-low pressure separation plate defines a second air discharging cavity with the bearing and the silencer respectively; the second air discharging cavity is communicated with the first air discharging cavity; the oil distribution structure is arranged in the first air discharging cavity and / or the second air discharging cavity; an oil return hole communicated with the second air discharging cavity and an oil pool is formed in the bearing. In the air discharging assembly of the compressor, the oil distribution structure can be used for distributing oil to separate oil liquid from a coolant; separated oil liquid can gather to the oil return hole and then flows to the oil pool by the oil return hole, so that the oil liquid can be used in a cycling manner, the oil discharging rate is reduced, the stabilization of the oil level of the oil pool is ensured, and the reliability of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor exhaust assembly and a rotary compressor with the compressor exhaust assembly. Background technique [0002] In related technologies, the exhaust cavity of a rotary compressor is generally composed of a bearing and one or more mufflers. The muffler can play a role in muffler, but the lubricating oil discharged along with the refrigerant cannot flow back into the oil pool, causing the oil in the oil pool to The reduction of liquid reduces the lubricating ability of the compressor. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a compressor exhaust assembly, which can have an oil separation function, can reduce the oil discharge rate of the compressor, and can improve the reliability of the compressor. [0004] The pre...
