VAIABLE DISPLACEMENT SLANT SHAFT TYPE HYDRAULIC ROTARY MACHINE

摘要

PURPOSE:To conduct tilting angle control with high accuracy by providing a tilting amount detecting means capable of preventing the whole structure from being complicated and miniaturizing the same. CONSTITUTION:A feed-back 1ink 28 is provided through a support pin 29 between a casing 22 and control part 23 of a hydraulic pump 21. While the lower end side of the feed-back 1ink 28 is connected to a valve plate 8 through a connecting pin 30, swing 1ink 27 and respective detecting pins 26, the detecting part 28B of the feed-back 1ink 28 is allowed always to abut against a detecting rod 33B of a tilting amount sensor 33 through a patch 28C. Thus, the wear of the detecting part 28B of the feed-back 1ink 28 caused by the contact with the detecting rod 33B can be remarkably reduced and the tilting angle theta of the valve plate 8 can be accurately taken out on the basis of the turning displacement amount of the feed-back 1ink 28 detected by the tilting amount sensor 33, so that the highly accurate feed-back control can be carried out with respect to the tilting angle theta.
