摘要： A hydraulic seal arrangement including first and second rotatable components, the first defining a first annular trough defined by radially inwardly extending first and second walls, the second component defining a radially outwardly extending web between the walls. The first component includes a second trough defined by the second wall and a third wall axially spaced from the second, the second trough defining an open radially inner end defined by a radially inner end of the second wall such that the first and second annular troughs fluidly communicate around the circumference of the first component via the inner end of the second wall. At a first circumferential position, the second wall of the first component defines a second trough oil inlet providing further fluid communication between the first and second troughs and at a second circumferential position, the third wall of the first component defines a second trough oil outlet.

摘要： A hydraulic seal (15) for providing a seal between two concentric shafts (10,12) of a gas turbine engine comprises a radially outer element (16) that defines an annular oil reservoir (21) and a radially inner element (22) having an annular fin (24) that projects into the oil reservoir (21). The radially inner seal element (22) is attached to its associated shaft (10) by frangible shear pins (26). In the event of relative axial movement between the shafts (10,12) the shear pins (26) break, thereby ensuring that such shaft relative axial movement is not unduly inhibited.

摘要： A pump incorporates a housing with a pump chamber and an internal bore communicating with the pump chamber, and a power driven impeller shaft supported in the housing by at least one bearing in the internal bore. The impeller shaft has an impeller in the pump chamber. A seal mechanism is in the internal bore between the bearing and the pump chamber providing a seal between the impeller shaft and the wall surface of the internal bore. The internal bore has a stepped configuration with small and large diameter portions and a vertical wall defined therebetween. The large diameter portion defines an intermediate chamber between the bearing and the pump chamber and that chamber connects with the pump chamber. The intermediate chamber contains liquid with air being trapped in the remaining portion of the intermediate chamber. The bearing and the seal mechanism are located in the small diameter portion. A partition wall member in the intermediate chamber divides the chamber into a first compartment adjacent the pump chamber and a second compartment adjacent the seal mechanism. The first and second compartments are connected at the upper and radially outer peripheral portion of the intermediate chamber. A device provided on the impeller shaft forces the liquid in the second compartment when the impeller shaft rotates, so as to displace into the first compartment, while the air concentrates in the second compartment around the impeller shaft, thereby excluding liquid from the sealing mechanism.

摘要： A hydraulic seal and an oil scavenge system are combined, and oil pumping gears and other associated equipment thus obviated. The hydraulic seal 32 comprises an oil reservoir holding centrifuged oil, and an annular fin 22, the periphery of which dips in the oil. The fin 22 has an orifice 33 which receives the oil under pressure derived from the speed of rotation of the oil, and passes it via conduit 34,26 to an oil sump.
