Patent ID: 7524172

Claim:
A reciprocating compressor comprising: a case having a suction pipe for introducing a refrigerant and a discharge pipe for discharging a refrigerant at both sides thereof; a cylinder installed in the case; a piston linearly-reciprocated in the cylinder and forming a compression space, for introducing a refrigerant into the compression space in an axial direction and compressing the refrigerant; a driving unit for linearly-reciprocating the piston; a discharge valve assembly installed at an end of the compression space of the cylinder to be opened and closed, for discharging a compressed refrigerant; a loop pipe installed between the discharge valve assembly and the discharge pipe with a curved shape, for preventing vibration generated from die cylinder, the piston, and the driving unit from being transmitted to the case; and a nonelastic connection unit for connecting a first point of the loop pipe and a second point of the loop pipe facing the first point and thereby reducing a vibration transmission, wherein the nonelastic connection unit includes a nonelastic vibration transmitting element configured to transmit vibration from the first point to the second point of the loop pipe, and wherein the nonelastic connection unit is installed completely to wind the first point of the loop pipe and the second point of the loop pipe multiple times at multiple locations along a predetermined length of the first and second points of the loop pipe.
