Abstract: The present invention prevents opening of a unidirectional flow control valve caused by an increase in the pressure in a sub port. A solenoid valve controls a flow rate of working oil flowing from a main port to a sub port, and includes: a main valve that enables communication between the main port and the sub port; a control pressure chamber that biases the main valve in a direction of closing the main valve; a first valve body provided in a main port communication passage that enables communication between the main port and the control pressure chamber; and a second valve body provided in a sub port communication passage that enables communication between the sub port and the control pressure chamber.

Abstract: A electric power steering device includes a basic return command value calculation unit configured to calculate a basic return command value in a direction to return a steering wheel to a neutral position on the basis of a steering angle of the steering wheel, a return command value calculation unit configured to calculate a return command value by correcting the basic return command value by the first correction gain, and an opposite return command value calculation unit configured to calculate an opposite return command value in a direction not to return the steering wheel to the neutral position on the basis of an angular acceleration of an electric motor. A correction return command value is calculated on the basis of the return command value and the opposite return command value and the electric motor is driven by adding the correction return command value to the assist command value.

Abstract: A solenoid valve includes a main valve that controls a flow rate of a working fluid, a sleeve in which the main valve is slidably inserted, and a solenoid unit that displaces the main valve. The sleeve includes a slide support and a large-diameter portion. The main valve is slidably supported by the slide support. The large-diameter portion is closer to an open end of the insertion hole than the slide support is, and has a diameter larger than an outer diameter of the slide support. The sleeve is fixed inside the insertion hole by causing the large-diameter portion to be pushed against the valve block by the solenoid unit.

Abstract: A cylinder device includes a piston rod that is inserted into a cylinder so as to be movable back and forth. The piston rod has a rod portion that extends outside the cylinder, and a piston connected to an end portion of the rod portion, the piston moving in the cylinder in a slidable manner. The rod portion has a rod inner space formed in the rod portion, the rod inner space communicating with the piston-side chamber of the cylinder, a first communicating passage that connects the rod inner space and the rod-side chamber of the cylinder, and an orifice plug provided in the first communicating passage in a changeable manner. The piston is connected to the rod portion so as to cover a part of the orifice plug.

Abstract: There is provided a damper that can reduce a shock when a piston speed reaches a high speed range from a low speed range without deteriorating a ride comfort while the piston speed is in the low speed range. In order to solve the above-mentioned problem, in a damper D of the present invention, since a orifice (7) and an opening/closing valve (9) are arranged in parallel with a bypass passage (B) bypassing a damping passage (3), and a valve opening pressure of an opening/closing valve (9) is made lower than a valve opening pressure of a damping valve (5), a sudden change in an inclination of a damping force characteristic can be moderated at an inflection point of the damping force characteristic even if the damping force is increased while the piston speed is in the low speed range.
