Dynamic lip seal and moveable seal recess for pressure balance control of electrically operated valve

An electrically or electromagnetically operated valve, comprising:

• a first structural element which can assume two positions by displacement along an axis, wherein in a first position at least on flow path is released, which is blocked in a second position,
• a second structural element surrounding the first structural element, wherein a circumferential sealing gap exists between the two structural elements,
• a dynamic seal which is arranged in the sealing gap and slides over a surface of the first structural element upon the axial displacement of the first structural element,
• wherein the dynamic seal is axially fixed on the second structural element, and the first structural element has two circumferential recesses of reduced respectively enlarged diameter, wherein the dynamic seal has two sealing lips which are seated in the two circumferential recesses in the first position and outside the two circumferential recesses in the second position so that the dynamic seal mutually seals the two structural elements radially in at least on axial position of the first structural element.
