RECIPROCATING COMPRESSOR AND ITS ASSEMBLING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent a valve plate and a delivery valve forming plate from being separated from each other even when they are reversed by assembling the delivery valve forming plate to the valve plate at the prescribed angle position in advance. SOLUTION: Multiple dowels 20 are formed on a valve plate 13. The dowels 20 are arranged at the positions corresponding to the positioning holes 22 of a delivery valve forming plate 18. When the valve plate 13 and the delivery valve forming plate 18 are to be assembled, the positioning holes 22 of the delivery valve forming plate 18 are inserted to the dowels 20 of the valve plate 13. The tip sections of the dowels 20 are caulked to be spread in the radial direction, and the delivery valve forming plate 18 is pulled and fixed to the surface on the cylinder cover side of the valve plate 13. The valve plate 13 and the delivery valve forming plate 18 are integrated in advance by this fixing. The valve plate 13 and the delivery valve forming plate 18 are sent to the next process in the integrated state in advance.
