Claims

[Claims for Utility Model Registration] 1. A cylinder main body formed by separating an upper cylinder and a lower cylinder with a partition plate is arranged directly above a rotor collar having a taper, and a follower piston is connected to the lower cylinder via a spring. 1. Attach a taper nozzle to the follower piston facing the taper, fit a pilot sleeve into the upper cylinder, fit a pilot valve into the pilot sleeve, and attach it to the follower piston. An upper hydraulic chamber that communicates with the inlet port and a lower hydraulic chamber that communicates with the slit port are formed in the main body of the cylinder that is connected to the piston and located above and below the pilot sleeve, and both hydraulic chambers are connected to each other by a communication hole. A shaft position detection device, characterized in that a guide hole is formed in a part of the lower hydraulic chamber, and an auxiliary nozzle is provided through the guide hole in the cylinder body located in the horizontal part of the rotor collar. . 2. The shaft position detection device according to claim 1 of the utility model registration, characterized in that an orifice is attached to the entrance side of the conduction hole that communicates with the lower hydraulic chamber. 3. The shaft position detection and suspension device according to claim 1 of the utility model registration claim, characterized in that an orifice and an on-off valve are attached to the entrance side of the conduction hole that communicates with the lower hydraulic chamber. 4. A utility model registration claim characterized in that an auxiliary piston equipped with an auxiliary nozzle is fitted into one lower cylinder near a follower piston having a tapered nozzle, and this auxiliary piston is connected to a pilot sleeve. The shaft position detection device according to item 1.
