摘要： A hydraulic damper including a tube defining a chamber. The tube has a main section and a narrowed section. A main piston assembly is disposed in the main section and connected to a piston rod. A resisting mechanism is fixed to the piston rod. A secondary piston is moveable into the narrowed section. An inner surface of the secondary piston defines at least one radially internal channel. The piston rod defines an annular recess. The secondary piston includes a locking mechanism axially slideable within the annular recess. The secondary piston is axially moveable between a hydraulic stop engagement stroke wherein the secondary piston engages the resisting mechanism and restricts the flow of fluid through the radially internal channel, and a hydraulic stop disengagement stroke wherein the secondary piston is spaced from the resisting mechanism and allows the flow of fluid through radially internal channel.

摘要： The rotary inertial mass damper has a configuration in which the rotary shaft of the oil-pressure motor rotates due to oil pressure of operating oil that is extruded from an oil chamber through reciprocating movement of the piston rod, and viscosity resistance is produced in operating oil that circulates in the connection pipes.

摘要： A damper assembly (20) is disclosed, and it comprises: a first rube (22) defining an inner surface (24) extending along an axis (A) to define a fluid chamber (30) containing a damping fluid (32); a rod (34) extending axially in the first rube (22); a guide (40) annularly disposed about the rod (34) and engaging the first tube (22); a piston (42) and a retainer (46) which are attached to the rod (34) and are slidably disposed in the first tube (22); a first spring (50) engaging and extending axially away from the retainer (46); a valve body (52) which is disposed adjacent to the first spring (50) and has a periphery (54) spaced from the inner surface (24) of the first tube (22) to define an annular channel (60); a second spring (66) extending axially away from the valve body (52); a bumper (68) engaging the second spring (66). The valve body (52) moves into sealing engagement with the retainer (46) in response to the bumper (68) engaging the guide (40). This causes the damping fluid (32) to move exclusively through the valve body (52) providing additional damping force.

摘要： A differential cylinder for a hydro-mechanical drive for actuating an electric switch, for example, a high-voltage switch, can include a first pressure area to be loaded with an operating pressure, a second pressure area, and a piston which can be moved in a movement range as a function of the pressure difference between the first and second pressure area. A damping device is provided which, during a movement of the piston in the direction of the second pressure area in one section of the movement range, provides damping against the movement of the piston, wherein the damping is adjustable.

摘要： Hydraulic bump stops and bi-directional diverter valves may be used to protect hydraulic systems, including, for example in one embodiment, the hydraulic actuators of an active suspension system, from damage due to operation outside the normal operating range of the system. In some embodiments, a hydraulic bump stop may be used to slow down the motion of a piston at the extremes of the compression and/or extension strokes of an actuator. In another embodiment, a diverter valve may be used to protect a hydraulic motor/pump in a hydraulic system from an over-speed condition. When the piston in an active suspension system actuator moves at a speed in excess of a threshold value, one or more diverter valves may be used to divert flow away from the hydraulic motor/pump. In some embodiments, a diverter valve may be a dual or single spool bi-directional diverter valve.

摘要： A shock absorber is disclosed having a secondary dampening assembly for dampening movement of an inner assembly within the shock absorber. The secondary dampening assembly includes a hydraulic stop piston and a hydraulic stop sleeve. The hydraulic stop piston is carried by an extender with a gap defined radially between the hydraulic stop piston and the extender to allow radial movement. The hydraulic stop sleeve has an open end for receiving the hydraulic stop piston and a flow groove that extends longitudinally along an inner surface of the hydraulic stop sleeve.

摘要： A fluid damper assembly for use in a vehicle includes a piston subassembly which includes a plurality of inflow passages and at least one rebound disk for restricting flow of hydraulic fluid through the inflow passages. A rod extends through the piston subassembly to actuate the piston subassembly between a rebound stroke and a compression stroke. An actuator supported by and within the rod includes a piezoelectric device and an amplifier for adjusting the damping force during the rebound stroke, thereby adjusting the suspension of the vehicle. A shaft within the rod is connected to a retainer to transmit motion from the amplifier to compress a spring and disengage the retainer from the rebound disk to allow the rebound disk to flex solely in response to hydraulic fluid pressure from the rebound stroke to open the inflow passages and reduce the damping force during the rebound stroke.

摘要： The damper assembly includes a tubular member, a rod, a primary piston, a secondary piston, and a resilient member. The tubular member includes a sidewall and a cap positioned at an end of the sidewall. The sidewall and the cap define an inner volume. The rod extends within the inner volume. The primary piston is positioned within the inner volume and coupled to the rod. The primary piston defines a first contact surface. The secondary piston includes a body member having a second contact surface, an opposing second surface, and an inner cylindrical face defining a central aperture that receives the rod. The secondary piston defines a channel extending from the inner cylindrical face to an outer periphery of the body member. The first contact surface and the channel are configured to cooperatively define a flow conduit upon engagement between the primary piston and the secondary piston.
