Regler zur Regelung eines mindestens einer Hydrostatik- oder Aerostatiktasche einer Lagerung, Gewindespindelmutter, oder einer Führung zugeführten Medienstromes

摘要

The invention relates to a regulator for adjusting the medium flow from a medium supply to at least one hydrostatic or aerostatic pocket of a bearing arrangement, a threaded spindle nut or a guide. Said regulator comprises a housing and pressure chambers which are separated by a control element that can be displaced by the force of a spring element. A first pressure chamber is subjected to a first pressure level (p1) and is directly connected to the medium supply. A second pressure chamber is subjected to a second, lower pressure level (p2) and is connected to the medium supply via a first medium resistance element. A third pressure chamber is subjected to a third pressure level (p3) which corresponds to the hydrostatic or aerostatic pocket, said third chamber being connected to the hydrostatic or aerostatic pocket. The regulator (1) is characterized in that the housing (7) has a support surface (19) comprising a passage orifice (30; 46) for the medium flow. When the regulator (1) is mounted, it rests on a counter surface (23; 23') located on the bearing arrangement, the threaded spindle nut or the guide so that a direct medium communication (3; 3') between the regulator (1) and the pocket and/or the medium supply is achieved.
