摘要:
A surface machining method to be adopted when machining a valve mechanism component member is provided so as to manufacture a product assuring a specific pulsation-reducing effect over an extended period of time with a high level of reliability. A plurality of recesses 60 are formed through laser machining over an area (seat surface 51) at a valve plate 2 around an suction port 24, which comes into contact with an suction valve 30, or an area of the suction valve 30 that comes into contact with the valve plate 2. Projections 61 may also be formed through laser machining around the recesses 60. Such projections 61 should be formed so as to assure hardness greater than the hardness of the other areas through radiation of laser light.
