Abstract

1,221,166. Shaft seals. COMPAGNIE FRANCAISE DES PETROLES S.A. 24 June, 1969 [23 Oct., 1968], No. 31911/69. Heading F2B. An electric motor 1 is lodged in a subaqueous watertight-vessel 2 having a gland 4 for the output shaft 3, leakage of water into the vessel past the bland being prevented by pressurized gas supplied to a vessel 7 at a lower level by a cylinder 12 through a pressure-sensitive regulating-valve 13. A duct 6 joins the two vessels; and an opening is provided in the bottom of the vessel 7. The gas pressure is such as to prevent water entering through the opening. The difference in the levels of the two vessels renders the gas pressure greater than the pressure of the water adjacent the gland.
