Abstract
Vibration absorbing device comprising a housing (12), a membrane (14) enclosed in the housing (12) and thus forming two chambers (18a, 18b) in the housing (12), said chambers (18a, 18b) being filled with a fluid, at least one weight (16), arranged on the membrane (14) in order that a movement of the weight (16) causes a movement of the membrane (14), and at least one duct (24) arranged to permit the fluid to flow between the two chambers (18a, 18b) if the membrane (14) and the weight (16) move.
Claims9
A vibration absorbing device comprising:
- a housing,
- a membrane enclosed in the housing and thus forming two chambers in the housing, said chambers being filled with a gas,
- at least one weight arranged on the membrane-so that a movement of the weight causes a movement of the membrane, and
- at least one duct configured to permit the gas to flow between the two chambers if the membrane and the weight move, the membrane being configured, upon said movement, to place each of the two chambers alternatively under positive or negative pressure, causing the gas to be displaced in the duct or ducts and thus dissipating the energy by the gas brushing against walls of the duct.
A component which may be subjected to vibrations, comprising a vibration absorbing device configured to at least partially absorb the vibrations to which the component is subjected, the device comprising:
- a housing,
- a membrane enclosed in the housing and thus forming two chambers in the housing, said chambers being filled with a gas,
- at least one weight arranged on the membrane so that a movement of the weight causes a movement of the membrane, and
- at least one duct configured to permit the gas to flow between the two chambers if the membrane and the weight move.
