Abstract
An aircraft engine fluid system comprises an open fluid circuit connected to a tank for distributing a fluid to a plurality of components. A component of the plurality of components has an enclosure having an internal chamber with an inlet port and an outlet port fluidly connected to the fluid circuit. The outlet port is positioned at a bottom end of the internal chamber. An outlet port extension tube extends upwardly from the outlet port to a top end of the internal chamber. The outlet port extension tube has a top open end fluidly connecting the top end of the internal chamber to the outlet port.
Claims13
An aircraft engine comprising:
- a plurality of components;
- and
- an oil system for distributing oil to the plurality of components;
- a component of the plurality of components including:
- an enclosure including an internal chamber having an inlet port and an outlet port fluidly connected to the oil system, the outlet port provided at a first location on the enclosure, and an extension tube extending upwardly from the outlet port to a second location inside the internal chamber, the second location at a higher elevation than the first location when the aircraft engine is in a horizontal orientation, wherein the extension tube has an upstanding portion extending from the outlet port inside the internal chamber, a top portion extending in a transversal direction away from the upstanding portion, and an elbow between the upstanding portion and the top portion, the elbow provided at a junction of a sidewall and a top wall of the enclosure, the top portion of the extension tube extending parallel to the top wall.
An aircraft engine comprising:
- an oil system fluidly connected to a plurality of components;
- a component of the plurality of components including:
- an enclosure including an internal chamber having an inlet port and an outlet port fluidly connected to the oil system, the outlet port positioned at a bottom end of the internal chamber, and an extension tube disposed inside the internal chamber and extending upwardly from the outlet port to a top end of the internal chamber, the extension tube fluidly connecting the internal chamber to the outlet port, wherein a top wall of the enclosure has an inner baseline surface, wherein a recess is defined in the inner baseline surface of the top wall to define a volume extension, and wherein the extension tube extends into the recess.
An aircraft engine fluid system comprising:
- an open-looped fluid circuit for distributing a fluid to a plurality of components, the open-loop fluid circuit including a fluid tank;
- and
- wherein a component of the plurality of components is disposed at a higher elevation than the fluid tank when the aircraft engine is in a horizontal orientation, the component including:
- an enclosure having an internal chamber with an inlet port and an outlet port fluidly connected to the open-looped fluid circuit, the outlet port positioned at a bottom end of the internal chamber, and an outlet port extension tube extending upwardly from the outlet port to a top end of the internal chamber, the outlet port extension tube having a top open end fluidly connecting the top end of the internal chamber to the outlet port, wherein the outlet port extension tube has an upstanding portion extending from the outlet port inside the internal chamber, a top portion extending in a transversal direction away from the upstanding portion, and an elbow between the upstanding portion and the top portion, the elbow provided at a junction of a sidewall and a top wall of the enclosure, the top portion of the outlet port extension tube extending parallel to the top wall.
