A cylinder assembly for a hermetic compressor is capable of reducing impulse
and
noise that is generated by a contact of a valve plate and a suction valve when
the suction valve is closed. The cylinder assembly has a cylinder block having
a cylinder formed therein; a cylinder head connected to the cylinder block, for
sealing the cylinder off from outside; a valve plate disposed between the cylinder
block and the cylinder head, the valve plate having a refrigerant suction hole;
a suction valve disposed at a side of the valve plate for resiliently opening and
closing the refrigerant suction hole; and a noise/impulse reducing device disposed
between the suction valve and the valve plate so that the noise/impulse reducing
device first contacts with the suction valve prior to contacting with the valve
plate. During the refrigerant compression in the cylinder, the impulse and noise,
which is generated by the hitting movement of the suction valve 38a against
the valve plate, is reduced.
