PROPORTIONAL PRESSURE ADJUSTMENT VALVE

摘要

A proportional pressure adjustment valve is described which comprises one valve part with inlet and outlet openings ( 4 ) and at least one closing mechanism ( 7 ) for control of a valve ( 12 ), the same as a magnet part having one magnet core, one magnet coil and one displaceably disposed magnet armature. An actuating element ( 11 ) cooperates with the armature, actuating the spherical closing mechanism ( 7 ). The hydraulically active cross section of the valve ( 12 ) is essentially determined by the length of the valve (L), the diameter of the valve (D) and th diameter (d) of the part ( 13 ) of the actuating element ( 11 ) which penetrates into the valve. According to invention, the ratio of the length of the valve (L) to the diameter of the valve (d) is less than 2.0.
