Abstract

The invention relates to a device ( ) for pressure regulation, having a housing ( ) and a closing body ( ) received axially movably therein, wherein the housing ( ) has at least one pressure medium inlet ( ) and one pressure medium outlet ( ), and the closing body ( ) is prestressed by a helical spring ( ) against a valve seat ( ) in the housing, and at least one compensation means for the helical spring ( ) is provided. The invention provides that as the compensation means, a compensation element ( ) disposed between the closing body ( ) and an end, oriented toward the closing body ( ), of the helical spring ( ) is provided, which is braced resiliently in the radial direction on the inner wall of the housing ( ) and, with its central region ( ′), is in preferably frictional-engagement contact with the closing body ( ). The central region ( ) of the compensation element ( ) is embodied as dome-shaped, and radially protruding spring arms ( ″) are disposed peripherally to the central region ( ) of the compensation element ( ).
