Abstract
PURPOSE:To make the maintenance of neutral position easy by providing friction portions in one portion of pistons or cylinder block bores. CONSTITUTION:Friction portions 25 are provided in the entrance portions A of cylinder block bores 17, and when the tilting angle of a cam plate is 0 deg., the friction portions 25 are situated on the entrance portions A of the cylinder block bores 17. The diameter of the friction portions 25 is the same as other portions basically, but if it is put in connection without hindrance with respect to the stroke of pistons 24, the diameter of the friction portions 25 may be smaller. The stroke of the pistons is small in neutral point neighborhood area with minute cam plate tilting angle by means of the friction portions 25 so that the friction portions 25 of all pistons always come in contact with the bore entrance portions A. Therefore the friction force between the pistons 24 and a cylinder block 11 becomes larger so that excellent neutral characteristics can be obtained.
