An oil tank assembly for a gas turbine engine may include an oil tank having an upper compartment and a lower compartment. A baffle may separate the upper compartment of the oil tank from the lower compartment of the oil tank. A de-aerator may be included, where the de-aerator includes an oil inlet, a de-aerator outlet, and an air vent. The de-aerator may be configured to separate air from oil in an air-oil mixture such that the oil flows through the de-aerator outlet and such that the air flow through the vent. Further, the de-aerator may include a fill port for receiving oil.

Seal arrangement (48) comprising a plug member (46) configured to seal a through opening (12) in a wall (10); a pressing section (74); and a cover member (70) configured to be connected to the plug member (46) and configured to force the pressing section (74) to press a sealing element (72), arranged laterally outside the plug member (46), towards the wall (10). A kit of parts and a method for sealing a through opening (12) in a wall (10) and for painting the wall (10) are also provided.

A lubrication system for an aircraft engine includes an engine lubricant tank including at least a supply port hydraulically connectable to the aircraft engine, a lubricant makeup port, and an overfill port, an auxiliary lubricant tank, a lubricant makeup conduit hydraulically connecting the auxiliary lubricant tank to the lubricant makeup port. The lubricant makeup conduit includes a pump operable to move lubricant from the auxiliary lubricant tank to the lubricant makeup port, and an overfill conduit hydraulically connecting the overfill port to the auxiliary lubricant tank. A method of operating a lubrication system of an aircraft engine of an aircraft is also disclosed.

A fluid drainage tool and method for utilizing the same is disclosed. The fluid drainage tool includes one or more pairs of vacuum members and a mechanical clamping mechanism. The mechanical clamping mechanism is coupled to the one or more pairs of vacuum members and is adapted to move the one or more pairs of vacuum members between an unclamped configuration and a clamped configuration. In the unclamped configuration, a gap formed by each of the one or more pairs of the vacuum members is larger than an original outer diameter of a pliable tube. In the clamped configuration, the gap is smaller than the original outer diameter of the pliable tube. In the clamped configuration, the one or more pairs of vacuum members compresses the pliable tube and generates a suction force within the pliable tube when translated along the pliable tube.

A lubricant filler for a lubricant tank of an aircraft engine comprises a filler tube having an upper portion to be disposed outside the volume of the tank and a lower portion to be disposed inside the volume. First and second openings are respectively provided in the upper and lower portions. An oil volume sensor is received in the filler tube through the first opening. A valve is connected to the filler tube and movable between an open position in which the valve provides a fluid connection into the lower portion via the second opening, and a closed position in which the valve blocks the fluid connection into the lower portion via the second opening. A third opening, smaller than both the first and second openings, defined one of: a) through a sidewall of the lower portion of the filler tube to provide a fluid connection between the volume and the lower portion when the lubricant filler assembly is attached to the lubricant tank, and b) through the valve to provide the fluid connection when the lubricant filler assembly is attached to the lubricant tank.

A fluid exchange service cart for performing fluid exchange service operations on a vehicle. The fluid exchange service cart additionally comprises an instrument panel and a number of panel loci to which the instrument panel may be detachably appended in different operating configurations.

An engine oil lubrication system includes an oil flow control baffle disposed in the sump of the oil pan. The baffle may be detachably mountable in the sump of the oil pan. The baffle may be configured to prevent oil returning to the sump from the engine from short-circuiting and flowing directly to the oil pump intake. The baffle creates a circuitous flow path which forces mixing of the returning oil before being drawn into the oil pump intake nozzle via increasing resonance time of the oil in the sump to enhance cooling. The present disclosure further provides a modular engine mounting system which extends the number of engines and vehicle chassis which can utilize a single oil pan to mount to the chassis. Interchangeable mounting flanges are provided having different bolting patterns compatible with the different chassis.

An oil change cap and system are described. A removable oil cap kit includes a removable oil cap and an oil retention bag. The removable oil cap incudes a sidewall and an interior surface, the interior surface has an opening extending therethrough. The sidewall includes an inner portion and an outer portion. The outer portion of the sidewall includes a channel formed therein for retaining an oil retention bag. The inner portion of the sidewall includes one or more protrusions to couple the removable oil cap with the oil receptacle of a motor.

An operation valve includes a valve that controls the flow of a fluid, a cylindrical operator that operates opening and closing of the valve by rotating the operator in a peripheral direction, and has a first step parallel to a central axis of the operator, a storage that stores the valve, includes a flow channel of the fluid therein, and has a second step corresponding to the first step on an outer periphery of the storage in a first state in which the valve is closed, and an elastic body that urges the operator toward the storage.
