  • Patent number: 10208828
    Abstract: A compensating damper comprises opposed working end faces (1788), a hermetically sealed chamber between the working end faces, and a set of plates (1701) in the chamber with a film of viscous fluid between each pair of adjacent plates. The damper has at least two different film thickness zones across the set of plates, each of the different film thickness zones providing a different resistance response when acted upon by an outside force exerted on at least one of the opposed working end faces. Multiple internal guide pins (1723) may extend axially from the opposed working end faces for engaging the plate stack partially from each of said working end faces to increase the stroke while providing for a compact damper. The plates may have a conical configuration to providing dampening in different plans.

  • Patent number: 9964170
    Abstract: A force limiting device comprises a housing defining an axially extending chamber containing a working fluid. A force transmitting member may be mounted for linear reciprocable movement inside the chamber under the action of external loads. An axial array of plates is floatingly disposed in the chamber between the force transmitting member and an end wall of the chamber. At rest, each plate is spaced from an adjacent plate by a gap occupied by the working fluid. When the force transmitting member is displaced towards the array of plates, the fluid in the chamber causes the plates to be successively pushed against each other, thereby causing some of the fluid to be squeezed out from between the plates.

  • Patent number: 5746915
    Abstract: A centrifuge includes an elastically supported centrifuge basket, a drive unit, and an endless drive arrangement, such as a drive belt arranged on a drive pulley of the drive unit and a driven pulley of the centrifuge basket support unit, for driving the centrifuge basket. A tension relieving device is provided for relieving or counteracting the tension forces of the endless drive arrangement. Thus the elastic supporting members of the centrifuge basket support unit are not stressed by the tension forces of the endless drive arrangement, and the tension relieving device can be pre-stressed so that the basket is in a neutral position during operation. For pre-stressing the tension relieving device, it includes an elastic thrust element, such as a compression spring packet, in addition to a length adjustable strut. To avoid tilting moments, the tension relieving device is arranged in a plane of the endless drive arrangement between the two pulleys.

    Abstract: A batch-type centrifugal system utilizes a gimbal-like suspension at the end of a rotating shaft distal an attached bowl at the other end of the shaft. The shaft rotates within an elongated bearing which is supported proximal the bowl by a support which is selectively variable in resiliency. This variation in resiliency changes the natural radial frequency of the system whereby operation of the system at rotational speeds which correspond to the natural radial frequency may be minimized, thereby effecting smooth loading, drying, and unloading operations.
