Hermetic Compressor

Abstract

A hermetic compressor capable of reducing vibration and noise caused by an oil-supply capillary tube during operation thereof. The hermetic compressor comprises a hermetic case, a cylinder block to guide reciprocating movement of a piston, a cylinder head coupled to an end of the cylinder block, a valve unit provided between the cylinder block and the cylinder head to control the flow of a refrigerant, an oil-supply capillary tube having a first end immersed in an oil sump that is defined in a lower region of the hermetic case and a second end communicating with the interior of the cylinder head to supply oil to the valve unit, and a fixing unit integrally formed at the cylinder head to fix the oil-supply capillary tube. With this configuration, the oil-supply capillary tube is securely mounted by the fixing unit during operation of the compressor, resulting in the reduction of vibration and noise.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority from Korean Patent Application No. 2005-35715, filed on Apr. 28, 2005 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 hermetic compressor and, more particularly, to a hermetic compressor capable of attenuating vibration of an oil-supply capillary tube, and noise caused by the vibration of the capillary tube. [0004] 2. Description of the Related Art [0005]FIG. 1 is a sectional view illustrating the general structure of a conventional hermetic compressor. Referring to FIG. 1, the conventional hermetic compressor is designed such that a crank 4 is connected at one end thereof to a lower end of a rotary shaft 3 and at the other end to a piston 5, thereby allowing the piston 5 to reciprocate in a cylinder 6 as the rotary shaft 3 rotates along with a rot...
