<p>PROBLEM TO BE SOLVED: To lessen abnormal sounds emitted from a refrigerant compressor in operation without increasing its costs resulting from an increase in the number of component parts used therefor. SOLUTION: A delivery valve sheet 42 comprises a baseboard 42a constituting an annular gasket part 32 and a delivery valve 17 arranged inside the annular gasket part 32. The baseboard 42a is coated on its surface and backside with layers 42b and 42c of an elastic member such as rubber. The delivery valve 17 is opposed to delivery ports 16 formed through a valve plate 2 so as to, when opened, cause a compression chamber and a delivery chamber to communicate with each other through the delivery ports 16. A suction valve sheet 41 comprises a baseboard constituting an annular gasket part 31 and a suction valve 21 arranged inside the annular gasket part 31. The baseboard is also coated on its surface and backside with layers of an elastic member such as rubber. The suction valve 21 is opposed to suction ports 15 formed through the valve plate 2 so as to, when opened, cause the compression chamber and a suction chamber to communicate with each other through the suction ports 16.</p> |
