Embodiment Construction

[0022] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023]FIG. 1 is a cross-sectional view illustrating the entire structure of a linear compressor according to the present invention. As illustrated in FIG. 1, the linear compressor comprises: a hermetically sealed container 10 having an airtight space defined therein; a compressing unit 20 for compressing a coolant introduced thereinto and discharging the compressed coolant; and a driving unit for driving the compressing unit 20.

[0024] The compressing unit 20 comprises: a cylinder block 21 having a compression chamber 21a where the coolant is compressed; a piston 22 disposed in the compression chamber 21a such that the piston 22 is reciprocated; and a cylinder head 23 having an inlet chamber 23a and an outlet chamber 23b. Between the cylinder block 21 and the cylinder head 23 is disposed a valve unit 24 for controlling the introduction of the coolant.

Abstract

A linear compressor having a dynamic vibration-reducing unit, which is provided at a stopper, by which separation of a cylinder block is prevented, for eliminating vibration generated from a hermetically sealed container at a specific frequency band. The dynamic vibration-reducing unit comprises an elastic member disposed at the lower end of the stopper, and a mass member fixed to the bottom part of the elastic member. The elastic member is formed in the shape of a spiral plate. The elastic member is provided at the center part thereof with a through-hole, which corresponds to an opening of the stopper. The elastic member is provided symmetrically at both ends thereof with fixing parts for fixing the mass member. The mass member is formed in the shape of a plate. The mass member is provided at the center part thereof with a hollow part, which corresponds to the through-hole of the elastic member. Through the hollow part of the mass member are inserted supporting parts of the stopper frame. Both sides of the mass member are symmetrical to each other centering on the hollow part so that both ends of the mass member are fixed to the fixing parts of elastic member by means of welding or bolts.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Patent Application No. 2004-15797, filed on Mar. 9, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a linear compressor, and, more particularly, to a linear compressor that is capable of eliminating vibration transmitted to a hermetically sealed container due to reciprocating movement of a piston, which is generated at a specific frequency band. [0004] 2. Description of the Related Art [0005] Generally, a linear compressor is used to compress a coolant of a cooling unit, such as a refrigerator or an air conditioner. The linear compressor is provided with a linear motor, which is linearly reciprocated, as a driving unit for moving a piston forward and backward. [0006] The linear compressor comprises: a cylinder block having a compres...
