A drain hole into which the drain bolt is screwed and a strainer hole are arranged coaxially. A crankcase is provided with an oil passage through which oil is returned to the sump. The oil passage includes a first passage through which the oil flows in a direction away from the strainer, a return passage that turns around from a forefront end of the first passage, and a second passage through which the oil flows from a forefront end of the return passage toward the strainer.

An oil sump, preferably made of plastic or metal, for motors or transmissions and having a filter housing, comprises a filter housing top shell, a filter housing bottom shell, a filter medium, a filter inlet, and a filter outlet, and an oil drain opening in the floor area of the oil sump, which is implemented in such a way that it is closable using an oil drain screw having external thread, which comes from the oil sump bottom side. The filter housing comprises an internal thread which is implemented to receive the external thread of the oil drain screw, the filter housing being at least partially fastened on the oil sump via the oil drain screw, which closes the oil drain opening and engages using its external thread in the internal thread on the filter housing side.

Disclosed is an opening and closing device including a closing member which is turned to an opening position by inserting a fuel-filling nozzle to open a fuel-filling aperture. The closing member includes a pair of flap bodies and a biasing device which positions each of the flap bodies in a closing position by a biasing force. The pair of flap bodies each includes a turning assembly portion as the center of the turning and an abutment portion with respect to the other flap body and is each configured to press its front surface portion against a hole edge portion of a passage hole of the fuel-filling nozzle by the biasing force and presses the abutment portion against the abutment portion of the other flap body.

A lubrication/bleeder fitting (10) is provided including a cap (14), a body (12) having a first end (15) coupled to the cap, a second end (17) opposite the first end, and an axially extending cavity (40) extending between the first and second ends. The fitting also includes a poppet seat (50) in the axially extending cavity and a poppet (60) disposed in the axially extending cavity and having a nose portion to seat against the poppet seat. A resilient member (64) is disposed in the axially extending cavity between the poppet and the second end, and a spacer (66) is disposed in the axially extending cavity and seating an end of the resilient member opposite the poppet. The poppet is biased in a first position against the poppet seat by the resilient member to prevent fluid flow through the axially extending cavity.

An oil sump with an oil drain channel for a motor vehicle has an oil sump wall with an oil sump inner side. The oil sump inner side delimits an oil sump storage space at least in some sections. The oil sump wall has an oil sump outer side, which faces an environment surrounding the oil sump. The oil sump further has two states, with, in the first state, a liquid medium being receivable and storable in the oil sump storage space, and in the second state, the oil sump storage space being fluidically connected to the environment surrounding the oil sump such that a liquid medium received can exit through the oil drain channel in an oil drain direction into the environment. The oil drain channel has an oil channel extension direction at least in the region of the transition from the oil sump wall into the environment surrounding the oil sump, which oil channel extension direction forms an angle of more than 85 and less than 95 in relation to a direction of the force of gravity, based on a correct installation position of the oil sump. An oil sump drip lug is arranged on the oil sump outer side, adjacently to the oil drain channel and protrudes at least 1 mm relative to an environment directly adjacent to the oil sump outer side.

A water pump drain plug has a first end which is adapted for engagement to a water pump drain opening which communicates with the pressurized fluid within the water pump. The drain plug has an axial passage communicating therethrough capable of draining fluid from the water pump. The axial passage is plugged initially by a sealing member engaged therein which will release upon communication of fluid pressure against it at a predetermined release pressure.

A drain plug for an engine collection pan has an external screw portion forming a threaded connection with the collection pan and a catch formed on the plug body. A lock ring axially slides on the plug body between a released position in which the lock ring does not interfere with rotation of the plug body relative to the collection pan to release the threaded connection and a locked position connected between the catch on the plug body and an external stop on the collection pan to prevent release of the threaded connection. A retainer on the plug body selectively retains the lock ring in the locked position. The lock ring is a robust structure, resistant to breakage even in colder climates. The axial sliding does not require any tool for application of torque to release the lock ring.

An oil pan for an engine comprises a containment portion of unitary construction. The containment portion has a circumferential component defining a circumferential extent of the containment portion and comprising a pair of mutually opposing side walls.
