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.

Disclosed is a device for lubrication of a unit turning under vacuum, such as a flywheel, where the unit includes an axle rotating relative to a fixed bearing structure, via at least one bearing or roller, and where the unit is placed in an enclosure connected to a vacuum, with: a lubricant reservoir connected by pipes both to the bottom of the enclosure and also to the bearing; and fluid suitable circulator for connecting the reservoir either to the vacuum, for filling the reservoir from the enclosure by gravity, or to the atmosphere for lubricating the bearing. The fluid circulator includes a three-way valve connecting the reservoir either to the vacuum or to the atmosphere.

A system for removing fluids, such as engine oil, from internal combustion powered vehicles is disclosed. The system includes a pump, an extraction line that connected between the pump and the oil pan drain (or other similar fluid receptacle drain) of the vehicle, a controller, a fluid storage container and a discharge line that is connected between the pump and the storage container. The fluid extracted is automatically transferred to a pressurized intermediate storage container and subsequently transferred to a non-pressurized final storage container.

An oil suction pump contains: an oil storage cylinder, a pumping mechanism, and a cap. The pumping mechanism includes a body, a drive rod, a plug, and a pressure relief valve. The cap is disposed on the body and the oil storage cylinder, and the cap includes a connector. The drive rod has a press lever, the cap further includes a first air conduit, a first one-way valve assembly, and a second air conduit. The second air conduit has an inlet segment, an outlet opposite to the inlet segment, and a pump segment defined between the inlet segment and the outlet segment and communicating with the oil storage cylinder. The cap further includes a second one-way valve assembly accommodated in the oil storage cylinder and connected with the pump segment, and the second conduit accommodates a pressure reducing valve.

An oil change machine or apparatus for removing used oil from an engine has flow lines for removing oil directly from the engine, which can be an automobile engine or a boat engine. The oil change machine can be configured to empty used oil to a designated waste oil bin. The oil change apparatus or machine can be located at a shop, can be portable and maneuverable from locations to locations, or be mounted on a service vehicle for on-site use, such as to perform oil change away from an oil lube center. The oil change machine can have adaptors for use with various engine models and can include an onboard offloading tank, in addition to a service holding tank, for performing multiple oil changes.

A system. The system includes a valve assembly. The valve assembly includes a first port, a second port fluidically couplable with the first port upon application of negative pressure at the first port, a third port fluidically couplable with the first port upon application of positive pressure at the first port, and a first check valve positioned between the first port and the second port. The system also includes a second check valve fluidically couplable with the third port upon the application of the positive pressure at the first port. The second check valve is positioned external to the valve assembly.

A device for reciprocatingly removing and replenishing fluid in circulating system of an hydraulic mechanism that includes at least two processing tanks, at least one air pressure regulator and connector releasably engageable with a pressurized air source, at least one vacuum generator, at least one pressure regulator; and means for removing the fluid from the circulating system at vacuum.
