摘要： A flow suppression device adapted to be connected to a high pressure fluid system includes an outer flow containment member of a porous and flexible construction. The outer flow containment member has an upstream end and a downstream end opposite the upstream end. The upstream end includes an inlet opening adapted to receive a flow stream of pressurized fluid from the high pressure fluid system and the downstream end being substantially closed. The flow suppression device also includes a primary inner flow containment member of a porous and flexible construction contained within the outer flow containment member. The primary inner flow containment member has an upstream end with an inlet opening adjacent the inlet opening of the outer flow containment member and a downstream end opposite the upstream end of the primary inner flow containment member.

摘要： A fluid-filled vibration damping device including a movable film housed within a housing space of a partition partitioning a pressure receiving chamber and an equilibrium chamber. An outer peripheral end of the movable film includes a contact part and a sealing part being respectively in contact with a pressure receiving chamber-side wall inner surface and an equilibrium chamber-side wall inner surface of the housing space. A communication passage, which communicates with a gap circumferentially between the movable film and the housing space, is provided away from the contact part in the outer peripheral end of the movable film. The outer peripheral end of the movable film will be separated from the equilibrium chamber-side wall inner surface due to a pressure differential arising between the two chambers so as to form a relief passage interconnecting the two chambers including the gap and the communication passage.

摘要： In a vibration isolation device 10, a connection rod 12 penetrates through a cavity part 104 of a rubber elastic body 44 and the inner circumferential side of a main body plate 14. In addition, a stopper rubber 98 fixed on the outer circumferential side of a rod main body 13 of the connection rod 12 is placed in the cavity part 104 of the rubber elastic body 44. This allows the rod main body 13 aligned in overlying relation with the rubber elastic body 44 along the axial direction of the connection rod 12 to be stored in the device. Thus, a stopper member 96 fixed to the rod main body 13 of the connection rod 12 can form a stopper mechanism. Therefore, while suppressing the increase in dimension along the axial direction of the device, the dimension along the axial direction of the device can be prevented from expanding by the stopper mechanism for preventing the excessive displacement along the direction orthogonal to the axis of the connection rod 12.

摘要： A fluid-filled vibration damping device including: an elastic body connecting a first and a second mounting member, defining a pressure receiving chamber undergoing pressure fluctuation during input of vibration; an equilibrium chamber defined by a flexible layer for permitting its volume change; an orifice passage connecting the pressure receiving chamber and equilibrium chamber; a movable member; and a short passage for connecting two chambers with a length smaller than that of the orifice passage. When pressure in the pressure-receiving chamber increases, the movable member is displaced or deformed toward to close the equilibrium-chamber-side opening of the short passage to have the short passage substantially closed, while when pressure in the pressure-receiving chamber decreases, the movable member is displaced or deformed to have the short passage operative.
