The invention relates to a safety valve (1) with an inlet (2) and an outlet (3) and a closing element (4) which seals the inlet (2) and moves under overpressure, thus opening a way from the inlet (2) to the outlet (3), wherein the closing element (4) is connected by at least one arm (5) to at least one spring element (6), against the force of which the closing element (4) moves during opening. According to the invention an arm (5) is provided, which connects closing element (4) and spring element (6), wherein the arm (5) is swivel-mounted respectively about an axis (7, 8) on the closing element (4) and on the spring element (6) and is rotatable around a further axis (9) arranged between the cited axes (7, 8) and is longitudinally displaceable with respect thereto, whereby an optimal adjustment of a spring force with respect to forces acting on the closing element (4) is given.
