초록 ▼

A method for manufacturing a first valve disc and a second valve disc for use in a compressor having a longitudinal axis and several cylinder chambers surrounding the axis is described. The method includes the steps of: providing a sheet of resilient valve material; stamping a through-hole having several extended openings out of the sheet to produce the first valve disc with several arms; and stamping several arch-shaped openings out of the sheet spaced around the through-hole corresponding to each of the extended openings of the through-hole to produce the second valve disc. Thus, an economical manufacturing method for obtaining a set of suction valve and discharge valve discs from a common surface area of sheet material is described. A small valve disc is obtained by stamping out the central portion of a larger valve disc. The total quantity of sheet material required for making a set of two kinds of valve discs thereby is reduced.
