Definitions

  • the present invention relates to a remote filling device for an oil tank. It applies in particular to the oil tank of aeronautical turbomachines.
  • the oil tanks of aeronautical engines are often placed in places of difficult access.
  • the filling of such a tank must therefore be done remotely, by connecting, on a filling port of the tank, a supply pipe.
  • a drain line for the oil overflow is generally connected to the tank.
  • the present invention relates to a filling device whose original design allows it to prohibit the connection of the supply line when the overflow discharge line is not connected. It also allows the degassing piping to be closed when filling the tank.
  • the means for automatically shutting off the supply pipe and the discharge pipe each comprise a passage, a drawer mounted to slide in the pipe and an elastic means normally keeping the drawer in a position for closing the passage. , the connection of the corresponding pipe having the effect of moving the drawer into an open position.
  • the locking means comprise a blocking member and elastic means making it possible to normally hold this blocking member in abutment against the evacuation drawer.
  • the blocking member thus occupies a position ensuring the blocking of the feed drawer in its closed position. This position of the blocking member is obtained when the evacuation pipe is not connected to the corresponding tubing. Conversely, when this connection is made, the blocking member unblocks the feed drawer.
  • the blocking member is advantageously a sliding member, a first end of which has a shape allowing it to fit into a notch in the feed drawer, when this drawer is in the closed position.
  • the second end is held by elastic means on a cam surface of the discharge drawer.
  • the feed drawer has a transverse opening ensuring the passage of air between the capacity and the degassing means when the feed drawer is in the closed position. Conversely, when the feed drawer is in the open position, access to the degassing means is impossible.
  • This device avoids overfilling an oil tank with remote filling.
  • the tank according to the invention has a capacity 2 capable of containing oil, into which an inlet pipe 4 of oil opens for manual filling, an inlet pipe 6 of oil from a system (not shown) for recovering used oil, and an oil discharge pipe 8 to a circuit (not shown) for supplying an engine.
  • a device 12 for detecting the low level, partially located in the lower part of the capacity 2, makes it possible to detect when the oil level reaches a minimum level N2 necessary for a suitable supply of the engine supply circuit.
  • the remote filling device 13, 21, 29 according to the invention is located in the upper part of the tank 2, near a maximum level N1 of oil in the tank.
  • the device comprises a supply pipe 16 and an overflow discharge pipe 24 opening into the tank 2, connected together by a locking device 29.
  • the supply pipe 16 is located above the pipe. discharge 24, the axes of these two pipes being horizontal.
  • the supply pipe 16 can receive on its threaded end 16a, an oil supply pipe 14.
  • This supply pipe 14 is removable and has, at its end, a nozzle 14a capable of being screwed onto the threaded end 16a of the supply pipe 16.
  • a supply drawer 18 slides inside the supply manifold 16.
  • This cylindrical supply drawer 18 has, near the threaded end 16a of the supply manifold 16, an end 18a of smaller diameter forming a shoulder which is normally supported by a seal 18d against a complementary shoulder formed inside the tube 16, under the action of a compression spring 20.
  • This spring 20 is trapped between the end 18b opposite the end 18a of the supply drawer 18 and a support piece 17 fixed on the supply pipe 16.
  • a passage 19 is formed in the drawer, between the end 18b and a part set back from the seal 18d relative to the end 18a of the drawer.
  • the spring 20 then places the drawer 18 in a normal closed position, in which the passage 19 does not communicate with the threaded end 16a of the supply pipe 16.
  • a part in projection 14b from the end of the supply pipe 14 pushes the slide 18 against the spring 20.
  • the passage 19 then communicates with the threaded end 16a of the supply pipe 16, thus allowing the filling of the capacity 2.
  • This same feed drawer 18 has, in its middle part, a notch 18c in the form of an annular groove.
  • the feed drawer 18 has a transverse opening 18e normally ensuring the passage of air between the interior of the tank 2 and the degassing pipe 10, itself connected to a non-degassing system. -represented in the figure.
  • the transverse opening 18e In the open position of the drawer 18, that is to say when there is remote filling of the capacity 2, the transverse opening 18e is displaced towards the support piece 17, thus preventing the air to pass through the slide 18 to pass into the degassing pipe 10. This passage of air being then suppressed, the oil, in the event of unlikely overfilling, could not escape through this degassing pipe 10, causing incidents cited above.
  • the permeability for the evacuation of air during filling being reduced, the return of oil by the overflow taking place at higher speed is improved.
  • the discharge pipe 24 can receive on its threaded end 24a a discharge pipe 22 of the overflow.
  • This evacuation pipe 22 is removable and has, at its end, a nozzle 22a capable of being screwed onto the threaded end 24a of the evacuation pipe 24.
  • This evacuation drawer 26 slides inside the evacuation tube 24.
  • This evacuation drawer 26, of cylindrical shape comprises near the threaded end 24a of the tube discharge 24, an end 26a of smaller diameter forming a shoulder which is normally supported by a seal 26d against a complementary shoulder formed inside the tube 24, under the action of a spring compression 28.
  • This spring 28 is trapped between the end 26b opposite the end 26a of the evacuation drawer and a support piece 25 fixed on the evacuation pipe 24.
  • a passage 27 is formed in the drawer, between the end 26b and a part set back from the seal 26d relative to the end 26a of the drawer.
  • the spring 28 then places the slide 26 in a normal closed position, in which the passage 27 does not communicate with the threaded end 24a of the evacuation pipe 24.
  • a part in projection 22b from the end of the evacuation pipe 22 pushes the slide 26 against the spring 28.
  • the passage 27 then communicates with the threaded end 24a of the evacuation pipe 24, thus allowing the evacuation of the capacity 2 overflow.
  • This same discharge slide 26 has, in its middle part, an annular cam surface 26c.
  • the locking device 29 connects, in a dependent manner, the feed drawer 18 to the discharge drawer 26.
  • This locking device 29 comprises a locking member 30 ensuring the operation of the locking device 29.
  • This blocking member 30 has the shape of a cylindrical pin formed by three adjoining parts of different diameters: a first part 30a forms a rod capable of bearing on the cam surface 26c of the discharge drawer 26; a second part 30b, overhanging the first part 30a, has the shape of a cylindrical plate; the third part 30c of the blocking member 30 has a diameter intermediate between that of the first part 30a and that of the second part 30b and is capable of fitting into the notch 18c of the feed drawer 18.
  • a compression spring 32 positioned around the third part 30c of the blocking member 30 and in abutment between the second part 30b of the blocking member 30 and the supply pipe 16 ensures, normally, the support of the first part 30a on the cam surface 26c of the discharge drawer 26.
  • the first part 30a of the locking member 30 is in contact with the part of smaller diameter of the cam surface 26c.
  • the third part 30c of the blocking member 30 is thus released from the notch 18c of the feed drawer 18.
  • FIG. 3A represents the normal state of the device, that is to say when there is no remote filling; the compression spring 28 is in the released position, the evacuation drawer 26 is in the closed position, the first part 30a of the blocking member 30 is in contact with the part of larger diameter of the cam surface 26c and the third part 30c of the blocking member 30 is fitted into the 'notch 18c of the feed drawer 18. Said feed drawer 18 is thus blocked; the connection of the supply line 14 is therefore impossible and the transverse opening 18e ensures the passage of air.
  • FIG. 3B shows the state of the device when the discharge pipe 22 is connected to the discharge pipe 24.
  • the connection of said pipe 22 has the effect of bringing the discharge drawer 26 into the open position, thus compressing the compression spring 28.
  • the first part 30a of the locking member 30 slides on the cam surface 26c and is installed in the part of smaller diameter of this cam surface 26c thus retracting the third part 30c of the locking member 30 out of the notch 18c of the feed drawer 18.
  • the feed drawer 18 is then released.
  • Figure 3C shows the state of the device according to the invention when the supply lines 14 and discharge 22 are connected to their respective tubing.
  • the supply drawer 18 being unlocked, as explained above, the connection of the supply line 14 can be carried out without problem.
  • This connection has the effect of pushing the feed drawer 18 into the open position, thereby compressing the compression spring 20, and displacing the opening transverse 18th.
  • the passage of air is therefore made impossible, which avoids, in the event of oil overfilling, the flow of oil to the degassing line 10.
  • the remote filling device of an oil tank according to the invention thus avoids a large number of incidents due to overfilling of tanks.
