Abstract
A device for reducing vibrations in a hydraulic system may have a separating device which has a side for delimiting a fluid-conducting cavity of the fluid system. The device may also have a vibration-reducing unit, which is designed to mechanically adjust the rigidity of the separating device such that vibrations in the fluid system are reduced.
Claims17
A device for reducing vibrations in a hydraulic system, comprising:
- a separating device which has a side for delimiting a fluid-conducting cavity of a fluid system, characterized by a vibration-influencing unit, which is designed to mechanically adjust the rigidity of the separating device such that vibrations in the fluid system are reduced, wherein the vibration-influencing unit is designed to adjust the rigidity of the separating device by a rotational movement.
A device for reducing vibrations in a hydraulic system, comprising:
- a separating device which has a side for delimiting a fluid-conducting cavity of a fluid system, characterized by a vibration-influencing unit, which is designed to mechanically adjust the rigidity of the separating device such that vibrations in the fluid system are reduced, wherein the separating device separates the fluid-conducting cavity from a second cavity, wherein a static pressure in the fluid-conducting cavity is compensated for by adjusting the gas pressure in the second cavity, and
- a second separating device, which is translationally displaceable and separates the second cavity from a third cavity, the third cavity being in a fluid connection to the fluid-conducting cavity.
A device for reducing vibrations in a hydraulic system, comprising:
- a separating device which has a side for delimiting a fluid-conducting cavity of a fluid system, characterized by a vibration-influencing unit, which is designed to mechanically adjust the rigidity of the separating device such that vibrations in the fluid system are reduced,
- wherein the vibration-influencing unit comprises a spring washer and a connector retainer mounted so as to be rotatable relative to the spring washer, the spring washer being in contact with the separating device via connectors connected to the spring washer in a stationary manner and the connector retainer being in contact with the spring washer via connectors connected to the connector retainer in a stationary manner.
