摘要： Oil grooves of a shutter and oil holes of a stepped rod constitute first orifices as variable orifices whose opening areas are variable according to the rotational position of the shutter. The oil grooves of the shutter and oil holes of the stepped rod constitute third orifices as variable orifices. Cut portions of inner disk valves constitute second orifices. The opening areas of the variable orifices are changed by rotating the shutter, thereby controlling damping force characteristics in a low piston speed region and the relief pressures of pressure control valves independently of each other, and thus increasing the degree of freedom for adjusting the damping force characteristics.

摘要： A shock absorber includes first passages configured to communicate two chambers to flow a working fluid therebetween by movement of a piston, and a second passage configured to communicate with one chamber of the two chambers. The first passages have damping valves configured to suppress a flow of the working fluid generated by movement of the piston to generate a damping force. The second passage has a variable orifice having an area adjusted by an elastic member when a piston rod moves in an extension direction, a pressure chamber installed in series with the variable orifice, and a free piston configured to vary a volume of the pressure chamber by movement of the piston.

摘要： To provide a rotor drive mechanism which realizes that a rotor rotating at high speed can be used by reducing the amount of heat and vibrations generated when the rotor is rotated at high speed and lowering a contact pressure between an outer surface of the rotor and an inner surface of a stator inner hole or preventing the outer surface of the rotor and the inner surface of the stator inner hole from contacting each other.A rotor drive mechanism (53) is capable of causing an external screw type rotor (22) of an uniaxial eccentric screw pump (23) to rotate and carry out a revolution movement, the uniaxial eccentric screw pump (23) is configured such that the external screw type rotor (22) is attached to an inner hole (29a) of an internal screw type stator (29), and the external screw type rotor (22) is caused to rotate by a rotation speed control driving portion (26) and is caused to carry out a revolution movement by a revolution speed control driving portion (24).
