    摘要： A gyroscopic stabiliser comprising: a support; a gimbal rotatable around a first axis relative to the support; a flywheel rotatable around a second axis relative to the gimbal, the second axis being orthogonal to the first axis; and a rotary damper for damping rotation of the gimbal around the first axis relative to the support; wherein the rotary damper comprises: a chamber containing a damping fluid; a vane that is rotatable within the chamber and that is coupled to the gimbal; and a flow passage allowing flow of the damping fluid from the chamber on one side of the vane to the chamber on the other side of the vane when the vane is rotated, wherein the flow passage comprises a flow valve configured to provide substantially the same flow rate of fluid through the flow passage for different torques applied to rotate the vane.

    摘要： A dashpot comprising a metal cylinder barrel (17) and a piston (24) slideable therein. A restricted fluid passage (78) is provided between a high pressure compartment (48) and a low pressure compartment (49) of the dashpot, which passage has a narrowest cross sectional area to determine a closing speed of the dashpot. The passage is formed from a first part (17) and a second part (47) having a different thermal expansion coefficient such that the cross sectional area is decreased when the temperature is raised and vice versa to compensate for temperature variations of the hydraulic fluid. A base part (47a) of the piston (47) is made of a glass fibre reinforced polymeric material to reduce the thermal expansion coefficient of the piston (47) such that the temperature compensation mechanism operates over a larger temperature range. An outer cover layer (47b) made from a less-abrasive material is provided around the base (47a) to reduce damage to the cylinder barrel (17).

    摘要： A rotary damper includes a housing and a rotor. The housing includes, inside a cylindrical surface, two plate-shaped fixed vanes. A fixed vane clearance portion is formed as such an inclined surface that both side walls of a tip end portion of the fixed vane extend inwardly in a thickness direction toward the tip end portion. The rotor includes, on an outer surface of a shaft body, two movable vanes. A movable vane clearance portion is formed as such an inclined surface that both side walls of the tip end portion of the fixed vane extend inwardly in the thickness direction toward the tip end portion. The rotor turns until part of a base portion of the movable vane enters a recessed cutout region of the fixed vane clearance portion.

    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 1 has a housing 2, a shaft 3, a vane 4, a sliding member 5, an O ring 6, and a cap 7 as main components. A blade portion 3c which protrudes at a predetermined height in an axial direction of a shaft portion 3a is formed on an outer periphery of the shaft portion 3a in a pressure chamber 2a of the housing 2. In the blade portion 3c, a portion of a center portion interposed between both end portions is cut out at a predetermined length, and thus, a cutout portion 3c1 is formed. On the other side surface B of the blade portion 3c, a first groove 3a1 is formed at a predetermined length and a predetermined width in a circumferential direction from a base of the blade portion 3c to the outer periphery of the shaft portion 3a. Moreover, on the outer periphery of the shaft portion 3a at a predetermined interval with the first groove 3a1, a second groove 3a2 is formed at a predetermined length and a predetermined width in the circumferential direction.
