項記載の容量可変型斜軸式液圧回転機。[Claims for Utility Model Registration] (1) A cylindrical casing having a head casing, a rotating shaft provided protruding within the casing, and a cylinder block provided within the casing that rotates together with the rotating shaft. , a piston that is reciprocatably provided on the cylinder block and whose one end side is swingably supported by the rotating shaft; one end surface is in sliding contact with the cylinder block, and the other end surface is in sliding contact with the head casing. In a variable capacity inclined shaft hydraulic rotating machine comprising a valve plate slidably in contact with a moving surface and a tilting mechanism that tilts the valve plate together with the cylinder block, the tilting mechanism The head casing includes a servo piston disposed on the circumferential wall of the head casing and a link mechanism connecting the servo piston and the valve plate, and the servo piston is attached to the head casing. A variable capacity oblique shaft type hydraulic rotating machine characterized by having a pair of supply/discharge passages located on both sides of the servo piston. (2) The servo piston is arranged to operate in a direction perpendicular to the axis of the rotating shaft, and the pair of supply/discharge passages are arranged so as to operate in a direction perpendicular to the axis of the rotating shaft, and the pair of supply/discharge passages are arranged so as to sandwich the servo piston in the lid wall of the head casing. (1) Scope of claim for utility model registration that is orthogonal to
Variable capacity oblique shaft type hydraulic rotating machine as described in .
