The present invention relates to a valve apparatus for a hermetic compressor. In the present invention, an elastic lead () is integrally formed with a discharge valve () in order to reduce striking force generated when the discharge valve () strikes a valve seat () and to facilitate opening of the discharge valve (). The elastic lead () is formed by cutting out an intermediate portion of the discharge valve (), and a free end of the elastic lead is bent to directed to a free end () or a clasped portion () of the discharge valve (). The free end () of the elastic lead () is supported on a bottom surface of a recess () in a valve plate (), and thus, the elastic lead () exerts elastic force on the discharge valve () in a direction that the discharge valve () is opened. According to the present invention constructed as such, noise generated when the discharge valve () operates can be minimized, and opening/closing operation of the discharge valve () can be smoothly performed.

Valve apparatus for hermetic compressor

An oil supply apparatus for a hermetic compressor includes: a crank shaft connected to a rotor of a driving motor so as to be rotated together with the rotor, and having an oil flow path therein; a sleeve connected at a lower end of the crank shaft so as to be rotated integrally together with the crank shaft; a sucking member disposed to maintain a certain gap against an inner circumferential face of the sleeve and sucking oil; and a support bracket installed between support springs installed between a bottom surface of a hermetic container and a stator of the driving motor so that the sucking member can be maintained in a suspended state inside the sleeve, and the sucking member. Since the plurality of legs are fixed as the seat cap is mounted between the support springs, the assembly of the sleeve and the sucking member can be simply assembled in a state that the motor and the compressing unit are already assembled. Thus, its assembling operation is simplified and an efficiency of the assembly operation can be improved.

Oil supply apparatus for hermetic compressor

The object of the invention is to provide an apparatus for noise depreciating in hermetic compressors. In the apparatus for noise depreciating for hermetic compressors of this invention, a diaphragm ( ) is mounted to the interior surface of a chamber cover ( ) through a welding process, thus dividing the interior of a muffling unit ( ) into two chambers ( and ). In a process of producing the above device, the chamber cover ( ), integrated with the diaphragm ( ), is locked to the top of a frame ( ) having the chamber ( ), with a packing ( ) being interposed along the junction between the cover ( ) and the frame ( ). In the device of this invention, an inclined part ( ) is formed along the edge of the diaphragm ( ), thus allowing the diaphragm ( ) to be easily and firmly integrated with the chamber cover ( ) into a single structure by a welded material C during a process of welding the diaphragm ( ) to the chamber cover ( ). The apparatus of this invention remarkably improves work efficiency and productivity while assembling and forming such apparatus for noise depreciating in hermetic compressors.
