Claim:
An electrically controllable valve for an adjustable shock absorber, comprising: a valve housing, an actuating drive, a first valve seat surface, a second valve seat surface, a valve closure member operable by the actuating drive, which is movable into abutment on the first or the second valve seat surface in the valve housing, the first and second valve surfaces being arranged in series connection to change a first and a second valve opening cross-section reciprocally in proportion to each other by means of the valve closure member, said valve further comprising an axial working air gap of the electric actuating drive arranged on a side of a magnet armature that cooperates with the valve closure member, said side facing away from the valve closure member, so that upon electric actuation of the actuating drive, the valve closure member is movable by the actuating drive in the direction of the first valve seat surface, wherein a first restrictor orifice is arranged between the first valve seat surface and the valve closure member, the restrictor cross-section whereof is smaller than a second restrictor orifice arranged between the second valve seat surface and the valve closure member.
