Claim 0:
1. A compressor comprising: a case; a compression unit comprising a cylinder that defines a compression space configured to receive refrigerant, a piston disposed inside the cylinder and configured to reciprocate in the cylinder, and a driver configured to reciprocate the piston in an axial direction; and a support unit that supports the compression unit such that the compression unit is spaced apart from an inner surface of the case, the support unit comprising a first wire spring assembly that includes: a first wire spring and a second wire spring that are symmetrically disposed, each of the first wire spring and the second wire spring having a first end portion connected to the compression unit, and a connecting portion that is supported by the case and connects a second end portion of the first wire spring to a second end portion of the second wire spring, wherein each of the first wire spring and the second wire spring comprises: a plurality of linear portions that extend parallel to one another, and a plurality of curved portions that connect together two adjacent linear portions among the plurality of linear portions, wherein the compressor further comprises: coupling bosses that are disposed at a rear end portion of the compression unit and connected to the first end portion of the first wire spring and the first end portion of the second wire spring, respectively, a suction cover that is disposed at the rear end portion of the compression unit, the suction cover defining a suction flow path configured to guide the refrigerant; and a fixing member that couples the suction cover to the compression unit, wherein the suction cover comprises coupling boss blocking parts coupled to the coupling bosses by the fixing member to thereby prevent the first wire spring and the second wire spring from being unexpectedly separated from the coupling bosses.
