FIELD: machine building.
SUBSTANCE: invention relates to the field of machine building. Pressure device contains stock (3) with a flange. Compression spring is installed on rod. Rod is installed with a gap in the hole of the cylindrical bushing with thread on its external diameter by means of which the cylindrical bushing is screwed into bracket (2) by means of thread. One end of the spring rests against the flange of the rod, and the other end is borne against the sleeve end. Movement of the stem relative to the bushing is limited by nuts screwed on it from the sleeve end opposite to the spring.
EFFECT: higher accuracy of force adjustment and simplicity of design.
