Abstract
Abstract A resilient mounting of a centrifuge that is a pneumatic one is made in a stand between the subsurface and supporting frame of the centrifuge by means of at least three vibration insulating units, each of which is provided with at least one pneumatic spring connected to a source of pressurized air through an automatic controller of a constant static height and having at least three vibration dampers. In a preferred embodiment, the resilient mounting of a centrifuge has three controllers of constant static height and vibration dampers which are seated obliquely.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
A resilient mounting of a centrifuge having a supporting frame, the supporting frame of the centrifuge being seated on a subsurface in an elastic way, comprising at least three vibration insulating units situated between the supporting frame and the subsurface, wherein each of said units consists of at least one pneumatic spring; a controller of static height; at least one vibration damper, wherein the pneumatic spring is connected to a source of pressurized air via said controller of static height, and the vibration damper absorbs vibrations of the working frame of the centrifuge.
Claim 2
Dependent Claim
93 words
