<p>PURPOSE:To variably form the cylinder displacement and smoothly operate the pressure control, by rotatably mounting a movable casing provided with a rotary shaft to a fixed casing provided with a rotary shaft and forming a spherical casing. CONSTITUTION:A spherical cylinder 1 is constituted by rotatably mounting a movable casing 1a to a fixed casing 1b. Rotary units 2, 3 provided to the point ends of rotary shafts 2a, 3a are rotatably housed in the spherical cylinder 1. Rotation of the rotary shaft 3a repeatedly decreases and increases respectively the displacements of plural chambers 17 formed by the rotary units 2, 3 and the cylinder 1. In this way, the volume of each chamber at a maximum is changed, and pressure can be smoothly controlled.</p> |
