ABSTRACT:
Method for producing a pressure plate used in a hydraulic pump by connecting first and second plate sections together include the steps of pressing metal powders to individually form the first and second plate sections and a ring member into predetermined configurations, placing the first plate section properly on the second plate section while the ring member is inserted in a bore formed in the first plate section, placing brazing metal along the upper side diameter of the bore, and heating the first and second plate sections and the ring member so as to connect the first and second plate sections and the ring member together by the brazing metal and simultaneously sintering the same.
