The foldable oil filter includes a cap receiving a filter; a drain pin disposed on a bottom side of the filter; and a capturing part disposed on a bottom side of the filter and detachably, rotatably capturing the drain pin.

Disclosed is an oil drain plug apparatus, wherein the oil drain plug apparatus is mounted on an automobile component containing a fluid including oil, and the oil drain plug apparatus includes a mounting portion provided on the automobile component and having a fastening hole penetrating the mounting portion; a plug portion configured to be inserted into the fastening hole and mounted on the mounting portion; and a sealing portion for sealing a gap between the mounting portion and the plug portion, wherein the sealing portion is mounted on the mounting portion while being coupled to the plug portion, wherein the plug portion includes a plug configured to be inserted into the automobile component through the fastening hole when coupled to the mounting portion; and a cap extending from the plug so as to be exposed to the outside of the automobile component through the fastening hole when coupled to the mounting portion, and the plug portion is rotated after being inserted into the fastening hole, and is fixed to the mounting portion, wherein one or more interference blades configured to protrude from the outer circumferential surface of the cap and bend toward the plug are formed on the cap to limit the rotation angle of the plug portion relative to the mounting portion. With this configuration, easy assembly may be realized, and maintainability and repairability may be improved.

A cylinder head for an internal combustion engine includes a casting and plug. The casting defines a first channel, a second channel, and a bore extending inward from an exterior surface of the casting. The first channel intersects a central portion of the bore. The second channel intersects an opposing end of the bore relative to the exterior surface. The plug is disposed within the bore. The plug has a distal end that engages the casting along the opposing end of the bore via a slip-fit engagement, a proximal end that engages the casting within the bore proximal to the exterior surface via a fixed engagement, and an intermediate portion that is spaced apart from the casting along the central portion of the bore. The plug defines an internal channel that establishes fluid communication between the first and second channels.

The invention relates to a fluid drain plug (10) for a fluid reservoir (50) with a drain hole (51), the plug having an extension in an axial direction (A) and comprising a body part (16) rotationally insertable into the drain hole (51), the body part having a proximal axial end (15), a distal axial end (17) and a substantially circular cross section with an outer surface (18), wherein the body part comprises a drain channel (92) having an inlet (91) located at the distal axial end and an outlet opening (94) disposed on the outer surface (18), the body part further comprising a bayonet-type connection slot (40) for accommodating a part of a radial projection (52) of a circumferential surface surrounding the drain hole (51), the bayonet-type connection slot being disposed on the outer surface and comprising an entrance (40a) at the distal axial end, a first path (41) and a second path (42), the first path (41) extending from the entrance, in the axial direction (A) and in one circumferential direction (C), to a first path terminal portion (70), wherein the first path terminal portion (70) is adapted to accommodate the radial projection (52), and the second path (42) extending from the first path terminal portion, in the axial direction (A) and in an opposite direction to the one circumferential direction (C), to a second path terminal portion (72), wherein the second path terminal portion (72) is adapted to accommodate the radial projection.

An assembly is provided for a fluid system. This fluid system assembly includes a fluid conduit and a plug. The fluid conduit has an internal bore. The internal bore is configured as or otherwise includes a smooth-walled internal bore. The plug includes a protrusion and a head. The protrusion is connected to the head. The protrusion projects axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug. The head is seated against the fluid conduit. The head seals an opening in the fluid conduit to the internal bore.

An oil leakage recovery system for recovering leaked oil in an oil system of a gas turbine engine The oil leakage recovery system includes a collecting reservoir having an inlet opening and an outlet opening each communicating with the oil system, a piston operatively mounted with the collecting reservoir and movable between a first position in which the piston is disposed away from the outlet opening to allow oil to leak from the collecting reservoir to the oil system and a second position in which the piston blocks the outlet opening to impede oil leaking from the collecting reservoir from the collecting reservoir to the oil system, and a pressure-controlled actuator system configured to move the piston to the first position when a pressure of the oil system is below a threshold pressure value and to the second position when the pressure of the oil system is above the threshold pressure value.
