A fluid supply system may include a component and a bypass valve including a valve body arranged in a control channel. The valve body may be adjustable at least between a first position and a second position, the valve body cutting off a fluid channel to the component when in the first position and cutting off a bypass channel bypassing the component when in the second position. The valve body may divide the control channel into a first chamber and a second chamber. The valve body may include a leakage opening connecting the first chamber and the second chamber. The system may also include at least one detection device configured to detect a property of a fluid and transmit the detected property to a control device. The control device may be configured to close a switchable valve arranged in the leakage channel when the detected property reaches a predefined condition.

An oil filtration system includes an oil chamber inlet. Also included is a first screen defining a first chamber volume that receives an oil flow from the oil chamber inlet, the first screen having a first mesh coarseness. Further included is a second screen surrounding the first screen to define a second chamber volume surrounding the first chamber volume, the second screen having a second mesh coarseness that is greater than the first mesh coarseness. Yet further included is at least one exit nozzle having an exit cross-sectional area that is greater than or equal to a cross-sectional area of apertures of the second screen. Also included is a bypass valve disposed in a first position during a first pressure condition within the first chamber volume and in a second position during a second pressure condition within the first chamber volume.

An assembly is provided for a turbine engine. This turbine engine assembly includes a turbine engine component and a lubrication system. The lubrication system directs lubricant through the turbine engine component. The lubrication system includes a wash flow filter.

An engine assembly includes a small air-cooled engine and a dry sump lubrication system including an external oil reservoir, wherein the dry sump lubrication system has an overall oil capacity that provides at least five hundred hours of engine oil life.

An engine oil supply system may include an oil pan connected with an oil pump at a first side and connected with an oil cooler at a second side, an oil passage through which oil pressurized by the oil pump flows, an oil filter disposed in the oil pan to filter impurities in the oil supplied from the oil pump, and a bypass valve disposed in the oil passage to selectively supply the oil in the oil passage to at least one of the oil cooler and the oil filter.

The present invention teaches a method and apparatus to quickly and inexpensively implement advanced, bypass grade, fine, or additional filtration to engines and hydraulic systems. The present invention has the ability to make quick hydraulic connection to the engine or hydraulic system, where oil is super cleaned, without major modifications as is the paradigm by traditional bypass filtration systems and without removing any lubricant from the engine or system that the present invention is connected to, as is the paradigm of traditional bypass filtering systems. When connected to the normally provided stud for the spin-on oil filter in an engine or hydraulic system, the net effect of interest to the present invention is that by simply placing the adapter at the point of connection of the spin-on oil filter, many of the necessary plumbing associated with the traditional bypass filter installation is obviated, as is the energy and labor intensive process of seeking for a pressure point and a return of the oil. The present invention relies on the differential pressure effected by either alone or in combination of an orifice restriction to effect flow of either engine oil or hydraulic fluid, to route through a high efficiency filter, in trapping and low pressure to flow, an amount of dirty oil and then to return same amount to reconstitute a total flow on the system, whereby supplemental or advanced filtration is quickly connected to an engine or hydraulic system.

An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate may be fixed with an outer enclosure and may be adapted for securing to the machine. The mounting plate may be further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve may be fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure. A secondary filter may have a second porosity greater than the first porosity, and may be fixed fluidly between the pressure-actuated valve and the central portion of the outer enclosure.
