摘要： A dasphpot damper for acting between two objects subject to move toward and away from one another including a housing including an elongated cavity, a piston mounted within the housing cavity for reciprocating movement therealong and dividing the cavity into two variable-volume, hydraulic fluid chambers, and a network of passages permitting hydraulic fluid to flow between the two variable-volume chambers as the housing and piston move relative to one another in response to relative movements between the two objects utilizes unitary flow control cartridge mounted within the housing and defining a passageway through which hydraulic fluid is forced to flow when passing between the two variable-volume chambers. The flow control cartridge also includes a check valve device associated with the passageway for controllably restricting the flow of hydraulic fluid in one direction through the passageway and for permitting substantially unrestricted flow of hydraulic fluid in the other direction through the passageway. By controlling the flow of hydraulic fluid through the passageway in the one direction, the damping effect of the damper is controlled. The flow control cartridge can be constructed so as to provide either an adjustable or fixed restriction to the hydraulic fluid flow in the one direction.

摘要： Apparatus is disclosed for protecting a structural object from the potentially harmful effects of a cyclic event such as an earthquake or high wind loads. A fluid spring is employed to stiffen the structural object and absorb kinetic energy stored by the spring. Fluid from the spring is exchanged with an accumulator where kinetic energy is dissipated as heat. A flow circuit regulates the exchange of fluid between the spring chamber and the accumulator chamber under controlled conditions to absorb the harmful effects of high external loads and to release the structural object when a high shock load is experienced.

摘要： An adjustable kinetic energy absorbing device wherein a piston is moved in response to an applied impact force along within a tube defining a chamber containing hydraulic fluid. The tube has a plurality of orifice openings therein spaced therealong in the direction of movement of the piston, and an elongated path is defined outwardly of the chamber, preferably in the outer surface of the tube, and in fluid communication with the orifice openings. The path is relatively narrow in width and extends along the tube. An elongated flow control element is supported in the device and movable lengthwise along the path in response to manual operation of an adjustment assembly including a cam operatively engaging the elongated element. The flow control element has formations spaced therealong adapted to register with the orifice openings to control flow of hydraulic fluid through the openings in response to movement of the element. A region in the device in fluid communication with the path receives fluid flowing through the orifice openings and along the path in response to movement of the piston.
