Abstract: The housing of a shock absorber is constructed to include an inner chamber surrounded by an outer chamber. The inner chamber is divided by the piston to which the piston rod is connected into two portions. One of these portion has a number of orifices that fluidly connect that portion to the outer chamber. A piston slidably and movably fitted along the length of the outer chamber divides the outer chamber into two compartments, one of which is in fluid communication with the portion of the inner chamber to which it is connected by means of the orifices. An incompressible fluid is provided in the fluidly interconnected compartment and portion. A biasing force acts against the piston in the outer chamber by means of a pressurized gas provided in the other compartment of the outer chamber. With the shock absorber thus constructed, when the piston rod moves, the piston to which it is connected would force an exchange of fluid between the inner chamber and the outer chamber, which acts as a reservoir. Both the size of the orifices and the pressure of the gas that acts against the piston in the outer chamber contribute to defining the stiffness of the shock absorber, i.e., how much dampening is to be effected to the movement of the piston rod relative to the housing. Another embodiment of the shock absorber partitions the outer chamber into three compartments, with the two end compartments being in fluid communication with the inner chamber. An alternative embodiment of the shock absorber is constructed with coacting pairs of plunger/bore and plunger/cavity for enhancing the damping effect of the shock absorber.

Abstract: A free run clutch apparatus is disclosed for damping movement of a device mechanically connected to the apparatus. The apparatus includes a housing which defines an enclosure and a rotor rotatably located within the enclosure, the rotor defining a cavity. A shaft has a first and a second end, the first end of the shaft being rotatably disposed within the cavity. A biasing device is disposed within the cavity between the first end of the shaft and the rotor. Also, a black oxide coating is coated on the biasing device such that when the shaft is rotated in a first direction, a free run of the biasing device within the cavity is permitted. However, when the shaft rotates in a second direction opposite to the first direction, the coated biasing device grabs the rotor so that damping of the rotation of the shaft in the second direction can be achieved.

Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.

Abstract: A rotary damper (10) includes a stationary member (12) and a rotating member (14) provided within the stationary member (12) so that a gap (16) is defined between the rotating member (14) and the stationary member (12). The rotating member (14) further includes a central shaft (18) provided therein. A viscous fluid (19) is provided in the gap (16) and has an associated shear that provides a velocity damping within the gap (16). A differential growth in the gap (16) caused by temperature variation compensates for temperature damping variation. A compliant member (20) is provided within the stationary member (12) for providing thermal compensation. A secondary hermetic seal (26) is provided on the stationary member (12) for permitting limited rotation, defining a vacuum environment and preventing viscous fluid leakage to an external environment.

Abstract: The disclosure relates to a rotary drag device having relatively rotatable members one (4) of which has a stack (5) of closely spaced, thin-walled flexible annular plates (20) peripherally mounted thereon to provide annular running faces and a viscous fluid filling the spaces between the plates, and the other (6) of which members has a stack (8) of segmental plates (33) having part-annular running faces interleaved with the annular plates to slide between the plates with relative rotation of the members. Slits (26, 27) in the annular plates permit release of viscous fluid from between the plates as fluid pressure rises ahead of the segmental plates with increasing relative speed between the members. The flexibility of the annular plates allowing the plates to close together accommodating the loss of viscous fluid from between the plates whereby the damping characteristic of the device can vary between viscous drag between the relative running surfaces of the annular and segmental plates at low relative speeds of the members and, with loss of viscous fluid from between the plates, can change to boundary lubrication between the running surfaces of the respective plates at higher relative speeds of rotation of the members.
