As shown in fig. 1 to 5, the present embodiment provides a discharge assembly for a linear compressor, which can be assembled and applied to the linear compressor. The exhaust assembly for the linear compressor is applied to the linear compressor, when the exhaust valve plate 5 is in a closed state, the coaxiality of the exhaust valve plate 5 and the end face cylinder hole of the cylinder base 1 can be always ensured, and the sealing performance between the exhaust valve plate 5 and the end face cylinder hole of the cylinder base 1 is remarkably improved. The exhaust assembly for the linear compressor of the embodiment has low cost investment and high reliability. In addition, the exhaust valve plate 5 can not be contacted with a conical spring steel wire when being opened and closed, and the noise performance of the compressor can be optimized.
The exhaust assembly for the linear compressor of the embodiment comprises an exhaust valve plate 5, a flexible spring 4, a cylinder cover 2 and a cylinder seat 1.
The exhaust valve plate 5 is disc-shaped, the outer end surface (the right end surface in fig. 1) of the exhaust valve plate 5 is of a plane structure, and the outer end surface of the exhaust valve plate 5 is used as a sealing surface, so that the exhaust valve plate 5 is tightly attached to a cylinder hole on the end surface of the cylinder base 1 when the exhaust valve plate 5 is in a closed state. A cylindrical first boss 51 is arranged in the middle of the inner end face of the exhaust valve plate 5, the radial size of the first boss 51 is smaller than that of the exhaust valve plate 5, a cylindrical second boss 52 is arranged in the middle of the end face of the first boss 51, and the radial size of the second boss 52 is smaller than that of the first boss 51. The exhaust valve sheet 5, the first boss 51 and the second boss 52 are all made of a non-metal composite material. The exhaust valve plate 5, the first boss 51 and the second boss 52 are integrally formed, so that the production process is simplified, and the integrated structure formed by the three is firmer.
