Apparatus for providing fine filtration to hydraulic systems and internal combustion engines

摘要

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 using any filter media through a single conduit means. 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. For canister type filters in engine or other applications, a single access point to the lubrication system is all what is needed. The present invention relies on the variable pressure of the working fluid, be it engine oil or hydraulic fluid, to route through a single bidirectional conduit means first to route to the high efficiency filter an amount of dirty oil and then to return same amount minus the inside volume of the single conduit an amount of super filtered oil from a combination of an accumulator, a high efficiency filter media and strategically located check valves to control such bidirectional flows through the single connection conduit.

1. An apparatus for providing fine filtration, to hydraulic systems and internal combustion engines, said systems and engines having a pressure variable lubricant working fluid, said apparatus hydraulically connected to said systems and engines through a bidirectional single conduit means accessing the variable pressure lubricant where said pressure variable lubricant is routed into the apparatus by a check valve chamber fluidly connected to said bidirectional conduit means to admit said working fluid into the apparatus through an inflow check valve fluidly connected to the inlet of a high efficiency filter where said working fluid flows through a high efficiency media and routed to the inlet of an accumulator where a charge volume of said working lubricant is returned to said hydraulic system and engines by said accumulator through said check valve chamber and through an outflow check valve hydraulically connected to said bidirectional single conduit means to discharge said charge volume back into said systems and engines, whereby the charge lubricant has been returned filtered by said high efficiency filter.
