A Forssberg -3 A SEAL DEVICE Abstract The invention concerns a method and a device for deminishing the over pressure that may occur in the oil housing if a seal leaks in a sumbersible machine such as a pump or a mixer. A non-return valve (2) is arranged in the wall (1) of the oil housing and has its inlet (3) near the bottom of the oil housing and its outlet (4) outside the wall (1). Incoming water is heavier than the oil and thus assembles at the bottom. By arranging the inlet (3) and adjusting the opening pressure of the valve it is secured that only water will be diverted through the valve. 24/55
