| description | PROBLEM TO BE SOLVED: To maintain a fitting condition between a slipper and a plunger main body even when a cylinder is rotated at a high speed under a lower oil pressure of a cylinder bore. SOLUTION: A plunger inserted into a cylinder bore freely slidably is constructed of a cup type slipper 205, a plunger main body 201 fitted to the slipper 205 freely slidably, and a joint member 210 connecting the slipper 205 and the plunger main body 201 together. An oil pressure controlling means is provided for controlling an oil pressure inside the cylinder bore so that a relationship F1>(F2+F3) is satisfied, when F1 represents a first axis directional force F1 pressing the plunger main body 201 according to an oil pressure inside the cylinder bore, F2 represents a second axis directional force F2 separating the plunger main body 201 according to an oil pressure of a sliding contact face with the slipper 205, and F3 represents a third axis directional force F3 separating the plunger main body 201 according to centrifugal force applied to the slipper 205 in a cylinder rotation time. |
