A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

Disclosed herein is a waste oil purification apparatus that purifies waste lubricating oil and waste oil at high speed by a precipitation induction method in a vacuum state and further completely removes metallic foreign materials, thereby improving the efficiency of the purification of waste oil. The waste oil purification apparatus may include a purifier configured to purify waste oil such as waste lubricating oil or general waste oil by a filtering method, and a separator configured to separate and remove foreign materials contained in the waste oil purified by the purifier.

A cleaning system of a vehicle oil circuit is provided, including a filter unit, an oil storage unit and a flushing unit. The filter unit includes a filter chamber, a first oil inlet tube and an oil outlet tube. The first oil inlet tube is communicated with a first opening of the vehicle oil circuit. The oil outlet tube is communicated with a second opening of the vehicle oil circuit. The oil storage unit includes a waste oil chamber and a second oil inlet tube communicated with a third opening of the vehicle oil circuit. The flushing unit includes a flushing chamber and a flushing tube. The flushing chamber receives a washing oil. The flushing tube is communicated respectively with the flushing chamber and a fourth opening of the vehicle oil circuit. The flushing tube guides the washing oil to enter the vehicle oil circuit.

A filter device may include a filter housing and a filter element defining a longitudinal axis disposed in the filter housing. The filter element may be configured to be penetrated by a fluid flow in a radial direction from a raw end to a pure end of the filter element. A water separator may be disposed at the pure end of the filter element and arranged axially spaced from the same. The water separator may have a hydrophobic and annular diaphragm extending in an axial direction of the filter element configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow.

A Filter for the removal of water from oil, the filter includes a distillation element having an inlet pipe that in one end is to be fluidly connectable to a reservoir of oil to be filtered, and in the other end being fluidly connected to a distillation head, said distillation head including a plurality of compressing tubes for injecting under pressure said oil into an evaporation chamber, whereby eventual water within the oil droplet evaporates from said decompressed oil, the filter further including a tubular core with a plurality of apertures and a hollow interior, said core having an open end for fluid communication with the hollow interior, a length of yarn wound around an outer surface of the core, wherein the filter further includes a device for blowing air or an inert gas into the evaporation chamber for removal of the water vapor during use of the filter. A method of manufacturing such a filter, as well as a method of removing water of is also disclosed. The water removal unit is part of a modular system, which makes the whole filter unit scalable within fixed steps. When water removing block with attached start block and end block, are stacked upon each other, and connected to filter unit, it becomes scalable complete cleaning equipment. Pump and motor must be adapted to each configuration.

A scavenge filter system according to an exemplary aspect of the present disclosure includes, among other things, a first scavenge pump stage positioned in a first flow path downstream of a first bearing compartment of a spool and a second scavenge pump stage positioned in a second flow path downstream of a second bearing compartment. The second bearing compartment houses a geared architecture mechanically coupled to the spool. A first scavenge filter fluidly couples the first scavenge pump stage to at least one oil reservoir. A second scavenge filter fluidly couples the second scavenge pump stage to the at least one oil reservoir. The first and second scavenge filters are separate and distinct. A method of filtering debris is also disclosed.

A filtration apparatus comprises a housing defining an internal volume sized to receive a filter element, an inlet for receiving a fluid and an outlet for expelling the fluid. A retention mechanism is disposed in the housing having a ball plug operatively connected thereto and selectively displaceable in an axial direction relative to the housing. An engagement member is disposed within the housing and comprises a port having an opening and a ramp. A portion of the port is disposed within the outlet. The ball plug is movable between a first position, in which the ball plug rests on the ramp, does not seal the opening of the port and fluid can be expelled from the housing port, and a second position in which the ball plug is aligned with the port, the ball plug seals the opening of the port and the fluid cannot be expelled from the outlet.

A fluid collection container includes a self-supporting, collapsible bag with a threaded cylindrical inlet ring or spout and a strainer removably seated within the ring. The strainer can separate a macroscopic solid object from a viscous liquid. The fluid collection container includes a rectangular prismatic box with the spout extending through and a threaded cap removably coupled to the spout. A method of draining automotive oil includes positioning the bag beneath an oil pan of an automobile, removing an oil plug from the automotive oil pan and allowing the oil plug to fall into the strainer; draining the automotive oil through the strainer into the bag; removing an oil filter from the automobile; removing the strainer from the inlet; inserting the oil filter; and screwing a threaded the cap onto the inlet.
