Abstract
The invention relates to an ancillary throttle (2) for gas bearings (1) which are exposed to such varying operational load conditions (F) as to change the magnitude of bearing clearance (S). The throttle (2) stabilizes the bearing clearance (S) by using the load-dependent internal pressure of the bearing (1) to regulate the cross section of the throttle. Inlet (13) and outlet (14) of the ancillary throttle are separated by a membrane (6) which displaceably carries an insert (9) having a slightly conical bore, and the insert (9) is adjustably preloaded by a spring (10). A pin (8), also conical, extends through the bore and coacts with the bore to establish a throttle path of variable cross section. The conical pin (8) is axially displaceable in order to adjust the flow of gas.
