Abstract
PURPOSE: To prevent a reverse rotation, by a method wherein bearing parts at a rotary shaft form a thrust bearing equipped with spiral groups, and a lubricant oil, fed to a ring channel, is controlled through the utilization of the pressure produced thereby as a pilot pressure for opening and closing a valve.
CONSTITUTION: A device is constituted such that a lubricant oil, which is controlled by a valve device 21 for utilizing as a pilot pressure a pressure generated through the operations to forcedly feed fluid by means of spiral groups 17 and 18 mounted at bearing parts 7a and 7b on a rotary shaft 7, is supplied into a cylinder 2. Thus, the smooth supply of a lubricant oil is conducted during the rotation of a rotor 1, and when thrust bearings 7a and 7b suspend performing the operations to forcedly feed resulting from the stoppage of the rotation of the rotor 1, the valve device 21 closes to suspend the supply of the lubricant oil to a ring channel 9. As a result, when the rotor 1 stops, a wedge oil film, produced in a gap 10 between the rotor 1 and side plates 5 and 6, is prevented from forming, and no difference in pressure is produced resulting from the leakage of fluid mutually between vane chambers in the cylinder 2. This permits the prevention of reverse rotation.
