Abstract
The invention pertains to a regulator for regulating a medium flow to at least one hydrostatic or aerostatic pocket of a bearing, a nut for threaded spindles or a guidance from a medium supply, with pressure chambers that are separated by a variable flow resistance control element that can be moved against the force of a spring element. A first pressure chamber is directly connected to the medium supply, a second pressure chamber that is charged with a lower pressure level is connected to the medium supply via a first flow resistance, and a third pressure chamber is charged with a third pressure level that corresponds to the pressure in the hydrostatic or aerostatic pocket.
