Abstract
The invention relates to a device (10) for pressure regulation, having a housing (11) and a closing body (12) received axially movably therein, wherein the housing (11) has at least one pressure medium inlet (21) and one pressure medium outlet (22), and the closing body (12) is prestressed by a helical spring (14) against a valve seat (11′) in the housing, and at least one compensation means for the helical spring (14) is provided. The invention provides that as the compensation means, a compensation element (15) disposed between the closing body (12) and an end, oriented toward the closing body (12), of the helical spring (14) is provided, which is braced resiliently in the radial direction on the inner wall of the housing (11) and, with its central region (15′), is in preferably frictional-engagement contact with the closing body (12). The central region (15′) of the compensation element (15) is embodied as dome-shaped, and radially protruding spring arms (15″) are disposed peripherally to the central region (15′) of the compensation element (15).
