Pressure valve

摘要

A pressure valve includes a spring plate configured to be displaced by a setting spindle. The setting spindle includes an adjustment screw configured to axially displace a spindle shaft on which the spring plate is provided. The adjustment screw and the spindle shaft are configured in such a way that virtually no torque is transmitted to the spindle shaft via the adjustment screw.

1. A pressure valve, comprising:
a valve housing; a spring plate arranged in the valve housing; a valve spring supported on the spring plate, the valve spring applying a spring force to a valve body; and a setting spindle configured to displace the spring plate so as to set the spring force, wherein the setting spindle includes a spindle shaft which is one-piece with the spring plate and is displaceably arranged in the valve housing and an adjustment screw which is configured to be screwed into the valve housing against said spindle shaft, and wherein the adjustment screw and the spindle shaft are configured to be moved relative to one another in a circumferential direction and the spindle shaft is configured for displacement together with the spring plate in an axial direction by the adjustment screw, wherein the spring plate defines a shoulder configured to bear against the valve housing and to limit displacement of the spindle shaft in the axial direction away from the valve spring, wherein the spindle shaft extends in the axial direction between the shoulder and the adjustment screw, and wherein the spindle shaft is configured to be displaced axially over an end face of the adjustment screw.
