Claims

[Scope of utility model registration request]

A cylindrical casing having a head casing, a rotating shaft provided protruding within the casing and having a drive disk formed at its tip, and a cylinder provided within the casing to rotate integrally with the rotating shaft. a plurality of pistons that are reciprocatably provided on the cylinder block and whose one end side is swingably supported by the drive disk of 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 cylinder block; A valve plate slidably abutting on the tilting sliding surface of the head casing, a center shaft rotatably supporting the cylinder block between the valve plate and a drive disk of the rotating shaft, and a center shaft attached to the head casing. In a variable capacity inclined shaft type hydraulic rotating machine comprising a tilting mechanism for tilting the head casing along the tilting sliding surface, the tilting sliding surface of the head casing is arranged so that the tilting sliding surface of the head casing is arranged along the tilting sliding surface of the head casing. A variable capacity oblique shaft type hydraulic rotating machine characterized by being formed by a concave curved arc surface centered on the actual force point of the resultant force of the average hydraulic reaction force acting on the drive disk.
