摘要： A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; and a valve that is configured to control a flow of the liquid in the flow passage. The flow passage formation part includes a first seat part that is provided radially outward of a flow passage port of the flow passage, protrudes from the flow passage port and contacts the valve, a second seat part that is provided radially outward of the first seat part, protrudes from the flow passage port and contacts the valve, and a circulation part having an orifice that allows the liquid to flow from the flow passage port toward the second seat part in a state in which the valve is in contact with the first seat part.

摘要： A rotary damper having a simple self-standing mechanism which does not cause an inconvenience such as bounce of an opening/closing member at an end of an opening operation of the opening/closing member such as toilet lid is provided. A rotary damper has a housing, a shaft, a vane, a sliding member, an O ring, and a cap as main components. A shaft portion, formed in a pressure chamber of the housing, includes a blade portion protruding in an axial direction of the shaft portion. A cutout portion is formed in a center portion between both ends of the blade portion. On another side surface of the blade portion, a first groove is formed in a circumferential direction from a base of the blade portion to the outer periphery of the shaft portion. A second groove is formed on the outer periphery of the shaft portion spaced from the first groove.

摘要： The invention describes a fluid damper for furniture parts that are movable relative to one another, said fluid damper comprising a piston (4) guided movably in a cylinder (1) along a longitudinal axis. At least one through opening (4.1, 4.2) for fluid flowing through is provided in the piston (4) and/or between the piston (4) and cylinder (1). A sleeve (2) is arranged so as to be radially rotatable, relative to the piston (4) against a spring loading, about the longitudinal axis or about an axis running parallel thereto, which sleeve comprises, on its circumference, a number of wings (2.1, 2.2, 2.1′, 2.2′) corresponding to the number of through openings (4.1, 4.2). The spring loading is directed such that the wing (2.1, 2.2, 2.1′, 2.2′) exposes the through opening (4.1, 4.2) when the piston (4) is stationary in the cylinder (1) and in the event of a movement in a movement direction of the piston (4) and of the cylinder (1) relative to one another along the longitudinal axis, and progressively closes said through opening in the event of a movement against the movement direction with increasing relative speed between the piston (4) and cylinder (1) along the longitudinal axis. The fluid damper comprises a hollow-cylindrical part of the piston (4), which surrounds the sleeve (2) and the at least one wing (2.1, 2.2, 2.1′, 2.2′), which is arranged on the circumference of said sleeve, along at least part of the longitudinal axis thereof.

摘要： A vehicle suspension damper comprises a cylinder and a piston assembly including a damping piston along with working fluid within the cylinder. A bypass permits fluid to avoid dampening resistance of the damping piston. A fluid path through the bypass is controlled by a valve that is shifted by a piston surface when the contents of at least one predetermined volume is injected against the piston surface which acts upon the valve. In one embodiment, the bypass is remotely operable.

摘要： A damper includes a cylinder, a rod including a first engaging portion at a tip end thereof, and a piston formed of an elastic resin material. The piston includes a convex portion provided so as to protrude at a base end portion located on a rod base end side and always in pressure contact with an inner circumference of the cylinder. During damper braking, the first engaging portion of the rod abuts against the other end portion of the piston, and an axial compression force acts on the piston between the first engaging portion and the convex portion in pressure contact with the inner circumference of the cylinder.

摘要： To provide a solenoid, a solenoid valve, and a damper in which when the amount of current supplied to the solenoid is small, the thrust of the solenoid to bias an object in one direction can be made small, and at the same time, even when the solenoid is not energized, the object can be biased in the same direction as that of the thrust. The solenoid includes a coil, a first movable iron core and a second movable iron core that are attracted in a direction away from each other by energizing the coil, a coil spring that biases the first movable iron core toward the second movable iron core, and a leaf spring that restricts the approach of the first movable iron core and the second movable iron core.
