Abstract:
1. A cylinder assembly of a hermetic compressor, comprising: a valve plate disposed on an outer side of a cylinder block to cover an open end of a cylinder, said valve plate having a refrigerant discharge hole therethrough adapted to discharge a compressed refrigerant from the cylinder; a cylinder head disposed to cover an outer side of said valve plate, said cylinder head defining a refrigerant discharge chamber in cooperation with said valve plate; a discharge valve disposed between said valve plate and said cylinder head in a cantilever manner, a center portion of said discharge valve covering said refrigerant discharge hole; and said cylinder head comprising a restricting mechanism comprising an integral first stopper member protruding from an inner wall of said cylinder head a distance such that a terminal end of said first stopper member is at a predetermined distance from a leading end of said discharge valve, said restricting mechanism for restricting a movement of said discharge valve, wherein during operation and opening of said refrigerant discharge hole, said discharge valve is deformed such that a center portion thereof deforms toward said cylinder head while the leading end is moved within a limited range due to said first stopper member impinging on said discharge valve.
