Abstract: A compressor is provided that may include a shell in which a discharge outlet may be provided; a cylinder provided inside of the shell and configured to form a compression space of a refrigerant; a piston provided inside of the cylinder and capable of reciprocating in an axial direction; and a discharge valve provided at one side of the cylinder and configured to selectively discharge a refrigerant compressed in the compression space of the refrigerant. The discharge valve may be formed with a magnesium (Mg) alloy in which the Mg has a weight ratio (wt %) of about 90 or higher, thus having a tensile strength of about 250 MPa or higher at about 150° C.
Abstract translation: 提供了压缩机，其可以包括可以设置排放出口的壳体; 设置在所述壳体内并且构造成形成制冷剂的压缩空间的缸; 设置在所述气缸内部并能够沿轴向往复运动的活塞; 以及排出阀，其设置在所述气缸的一侧，并且构造成选择性地排出在所述制冷剂的压缩空间中被压缩的制冷剂。 排出阀可以由Mg（Mg）合金形成，其中Mg的重量比（wt％）为约90或更高，因此在约150℃下具有约250MPa或更高的拉伸强度。

Abstract: A linear compressor is provided that may include a cylinder, to which a discharge valve may be coupled; a first piston, which may be provided to enable a reciprocating motion in an inside of the cylinder; a second piston, which may be provided to enable a reciprocating motion in an inside of the first piston; a first compression chamber formed between the discharge valve and the first piston; and a second compression chamber formed between the first piston and the second piston. The first piston and second piston may move in opposite directions with respect to each other.

Abstract: A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.
