Patent ID: 6989729

Claim:
A proportional pressure control valve ( 1 ), for controlling a pressure level in a hydraulic circuit, comprising: a push rod ( 5 ) connected between a control element ( 13 ), arranged in the hydraulic circuit, and a proportional magnet, located in a housing ( 10 ), the proportional magnet comprises a magnetic core ( 2 ), a magnetic anchor ( 3 ), and a magnetic coil ( 4 ); wherein the magnetic coil ( 4 ) and the magnetic core ( 2 ) are securely connected to the housing ( 10 ); the magnetic anchor ( 3 ) includes a first part securely connected with an axial anchor rod ( 6 ); the push rod ( 5 ) couples the first part of the magnetic anchor ( 3 ) to the control element ( 13 ); the magnetic core ( 2 ) has a magnetic control edge ( 12 ) and the first part of the magnetic anchor ( 3 ) is axially movable back and forth relative to the magnetic core ( 2 ) between opposed first and second end positions by magnetic force for controlling actuation of the control element ( 13 ); a width of a magnetically acting gap ( 11 ), formed between front faces of the magnetic core ( 2 ) and the first part of the magnetic anchor ( 3 ), is adjusted to a maximum possible value by movement of the first part of the magnetic anchor ( 3 ), via the magnetic force, toward the second end position; and a second part of the magnetic anchor ( 3 ″) is arranged to be movable relative to the anchor rod ( 6 ) in dependence upon the magnetic force so that one of a first gap ( 14 ), which is enlarged with respect to the magnetically acting gap ( 11 ), and an additional second gap ( 8 ) is produced.
