ABSTRACT:
The present invention relates to a valve apparatus for a hermetic compressor. In the present invention, an elastic lead (40) is integrally formed with a discharge valve (30) in order to reduce striking force generated when the discharge valve (30) strikes a valve seat (26) and to facilitate opening of the discharge valve (30). The elastic lead (40) is formed by cutting out an intermediate portion of the discharge valve (30), and a free end of the elastic lead is bent to directed to a free end (36) or a clasped portion (32) of the discharge valve (30). The free end (36) of the elastic lead (40) is supported on a bottom surface of a recess (27) in a valve plate (20), and thus, the elastic lead (40) exerts elastic force on the discharge valve (30) in a direction that the discharge valve (30) is opened. According to the present invention constructed as such, noise generated when the discharge valve (30) operates can be minimized, and opening/closing operation of the discharge valve (30) can be smoothly performed.
