Abstract: A damper includes a coil that generates a magnetic field acting on magneto-rheological fluid flowing through a communication passage. A piston includes a concave portion formed on an outer peripheral surface of a piston core, a regulating member housed in the concave portion, an introduction flow passage that guides the magneto-rheological fluid in a first fluid chamber or a second fluid chamber into the concave portion such that the regulating member projects into the communication passage, and a fail valve that opens and closes the introduction flow passage. In the case where a current applied to the coil is a predetermined value or less, the regulating member projects into the communication passage.

Abstract: A control system of a hybrid construction machine includes fluid pressure pumps configured to supply a working fluid to a fluid pressure actuator, a regeneration unit having a regeneration motor for regeneration to be rotated by the working fluid discharged from a load side pressure chamber of the fluid pressure actuator, a rotating electric motor coupled to the regeneration motor, and a storage battery configured to store electric power generated by the rotating electric motor, and a variable throttle configured to bleed a portion of the working fluid obtained by excluding a flow rate of the working fluid guided to the regeneration motor from the working fluid discharged from the load side pressure chamber.

Abstract: A damper includes a cylinder into which magneto-rheological fluid is sealed, a first fluid chamber and a second fluid chamber, a throttle passage, an electromagnetic coil, and a spacer. The first fluid chamber and the second fluid chamber are partitioned by a piston core in the cylinder. The throttle passage is formed between an inner peripheral surface of the cylinder and an outer peripheral surface of the piston core. The throttle passage communicates between the first fluid chamber and the second fluid chamber. The throttle passage provides a resistance to a flow of the passing magneto-rheological fluid. The electromagnetic coil generates a magnetic field acting on the magneto-rheological fluid flowing through the throttle passage. The spacer is mounted to the piston core and is configured to adjust a length of the throttle passage.

Abstract: A damper includes a cylinder that seals a magneto-rheological fluid, a piston slidably disposed in the cylinder, and a piston rod coupled to the piston. The piston includes a piston core, a flux ring, a plate, and a fixing nut. The piston core is mounted on the piston rod. The piston core has an outer periphery on which a coil is disposed. The flux ring forms a flow passage for the magneto-rheological fluid with the piston core. The plate is disposed on an outer periphery of the piston rod, has an outer peripheral surface housed in a one-end of the flux ring, and is bonded on the flux ring by brazing. The fixing nut sandwiches the plate with the piston core.
