US 12,716,462 B2 · Vibration isolator for supporting a payload

Abstract

A vibration isolator (10; 210) for supporting a payload and isolating the payload from vibrations has a contact member (12) configured for supporting the payload, at least two pressurized gas compartments (24) arranged offset from each other to support the contact member at different locations, which pressurized gas compartments are connected to each other via a tubing system (54). The tubing system contains at least one restriction (66) at which a cross section of the tubing system is reduced by at least 50%.

Dependent claims

A vibration isolator for supporting a payload and isolating the payload from vibrations, comprising:

a contact member configured for supporting the payload,
at least two pressurized gas compartments arranged offset from each other to support the contact member at different locations, which pressurized gas compartments are connected to each other via a tubing system, wherein the tubing system has a non-uniform cross section and contains at least one restriction at which the cross section of the tubing system is reduced by at least 50%;
and
a control valve configured to control a pressure supplied by an outlet of the control valve to the gas compartments based on a control signal and further comprising a damping chamber arranged such that the outlet of the control valve is connected to the tubing system via the damping chamber.
