摘要:
A pressure gradient dosing system is provided for a fluid supply system. A flow passage has first and second pressure zones having a pressure gradient therebetween. An additive reservoir in an additive delivery system responds to the pressure gradient to release additive to the flow passage.

A coalescer has variable characteristics including variable diameter of individual fibers along their length such that an individual fiber has differing diameters at different points along its length, and including variable porosity.

Method and apparatus are provided for making a filter element by spinning fibers from one or more dies onto a collector, including designated combinations providing designated filter characteristics.

A coalescer includes fibrous media capturing droplets of the dispersed phase, coalescingly growing the droplets into larger drops which further coalesce and grow to form pools that drain, and adapted to reduce pressure drop thereacross by increasing dispersed phase drainage therefrom.
摘要:
A filter has multiple pleated filter elements having axially extending channels having a transverse pleat channel height and a lateral channel width. The pleated filter elements have different channel heights.
摘要:
Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.
摘要:
A simple pass-fail tool that can be used to test the particulate contamination level in a fluid. The tool relies upon a comparison between a measured indicator of the contamination level in the fluid with another indicator of a contamination level of the fluid. Based on the comparison, conclusions about the contamination level of the fluid, and decisions about the fluid, for example that the fluid is acceptable for a particular use, can be made. The fluid can be fuel, lubrication, power transfer, heat exchange or other fluids used in a fluid system, for example fuel injection systems of diesel engines or hydraulic systems, where contamination of the fluid is of concern and use of an excessively contaminated fluid is to be avoided.
