Claims

[Claims for Utility Model Registration] (1) A fixed orifice with a gradual slit shape and a variable orifice whose position can be changed mechanically or electrically are arranged so as to overlap on two discs. A variable damper characterized in that the effective orifice area is continuously varied by rotating the variable orifice. (2) A fixed orifice with a gradual slit shape and a variable orifice whose position can be varied mechanically or electrically are arranged in the circumferential direction on two overlapping cylinders, and the variable orifice is rotated. A variable damper characterized by continuously varying the effective orifice area. (3) A fixed orifice with a gradual slit shape is arranged in the longitudinal direction, and a variable orifice whose position can be changed mechanically or electrically in the longitudinal direction is arranged on two overlapping cylinders, and the variable orifice A variable damper characterized by continuously varying the effective orifice area by vertically moving the damper. (4) A fixed orifice with a uniform or non-uniform slit shape is arranged on a disk, and a shutter that rotates mechanically or electrically and blocks a part of the fixed orifice is provided on the disk, and the effective orifice area is A variable damper characterized by continuously variable. (5) A fixed orifice with a uniform or non-uniform slit shape is arranged on a disk, and a shutter is provided on the cylinder that moves up and down mechanically or electrically and blocks a part of the fixed orifice, and the effective orifice area is A variable damper characterized by continuously variable. (6) A fixed orifice with a uniform or non-uniform slit shape is provided on the cylinder, and a shutter that rotates mechanically or electrically and blocks a part of the fixed orifice is provided on the cylinder to increase the effective orifice area. A variable damper characterized by being continuously variable. (7) A variable damper characterized by continuously changing the passage of damper oil, etc. by inserting a tapered rod into a fixed orifice.
