Definitions

  • This invention is a connecting means for use between two sources of fluid pressure whereby pressure in one will be automaticallymaintained below that of the other and the pressure diiference keptwithin comparatively narrow limits, even though there be a comparatively wide variation of the higher pressure.
  • the invention may be used forvarious purposes, but we have particularly in mind pressure of the fuel oil tank of submarines.
  • Such tanks are commonly situated 'outslde of the main hull of the submarine and the walls are not built to resist very great pressure differences onopwalls without the strain developing leaks.
  • the escape of oileither owing to leaks or in consequence of the direct connection of the tankswith the water betrays the position of the boat by floating 35 onthe surface of the water.
  • the present invention is a device. for automatically maintaining in the interior of the tanks a pressure which is less than the 1 pressure of the water surrounding the tanks.
  • the said. device may for instance comprise a] differential piston interposed; between the tanks and the water surrounding them, with the larger surface under the influence of the pressureof the oil in the tanks and the smaller surface under the influence of the pressure of the surrounding water.
  • the movement of this piston being thus dependent on the external pressure of the water and the internal pressure of the oil in the tanks may also permit.
  • the compensating liquid may be the surrounding sea water and may, withoutdetriment, be first utilized to operate the differential piston itself and then be allowed tov pass into the interior of the tanks, the piston acting as a valve to control the entry of this liquid.
  • Any well known kind of reversing device may be employed for reversing-the piston at its extreme positions.
  • the accompanying drawing shows dia-. grammatically in cross section a submarine provided with a form of the invention.
  • A represents the hull of the submarine and A one of the oil tanks.
  • B represents a pipe leading to the tank A through a valve or cock I), and C represents another pipe leading to the exterior of the submarine through a valve or cook 0. Between the pipes B and C,
  • the apparatus therefore keeps up the reductionof pressure in the tank evenwhen the'slib marine rises to thesurface until the volume in the cylinderbetween th'elopenings b and c is used up,but this does'not occur f I within widediving limits providedthat no appreciable'volume-of air exists in the tank.
  • V v r 3;.,A submarine having an oil tank and connections between said tank and the outside seawater including a differential piston having its larger surface exposed to the pressure in the tank and its smaller surface exposed to the pressu're ofthe sea water.
  • v I a submarine having an oil tank and a differential pressure device which is interposed between the tanks and the water sur rounding. themand .is under the influence of the pressure in the. tanks and the pressure'of the surrounding water, substantially as described.
  • v I a Two sources of fluid pressure and aconnection between including a diiiferential pis- .ton having'one surface exposed to the presi sure of one source and the other exposed to the pressure ofthe other source, and means for establishing a by-pass around said piston when the latter is in either of itslimiting positions.
  • v I 7 6.
  • Two sources of fluld pressure and a connectionbetween including a diiferential piston having one surfaceexposed to the'pressure of one source an'dthe other exposed to the pressure of the other source and means forestablishing direct connection between said'sources when the piston is in either "of its limiting positions.
  • Means for preventing the escape of oil from the oil tank of a submarine comprising a cylinder having one end connected to the tank and the other end connected to the sea, and a differential piston within said cylinder and separating said ends, said cylinder having ports adjacent to each end thereof and uncovered to permit free flow through the cylinder between the tank and sea whenthe Signed at Hamburg, in the county of Hamburg and State of Hamburg, this 6th 25 day of August, 1921.
