HIGH-PRESSURE LIQUID FILTER WITH SUPPORT STEM AND APPLICATION OF THIS FILTER IN FUEL SYSTEM

摘要

This description presents liquid filter comprising filter housing containing all parts of the filter; filtering element trapping impurities present in liquid being filtered; solid support element preventing filtering element from getting deformed, filter housing cover, and other components. The most important element presented in this description is filter support stem enabling the use of filter with extreme pressure levels of the filtered liquid (up to 300MPa) and sudden changes to these levels. The support stem prevents filtering element from getting deformed to the extent that would render it unfunctional. One of the possible applications of the filter presented herein is filtering high- pressure diesel fuel between high-pressure pump and injectors. An important feature of this liquid filter is that it is not integrated into other standard parts of fuel system, but added to fuel system as separate component that can be easily replaced without replacing other parts of the system. To improve durability and ensure reusability of filtering element of liquid filter this element is made of metal or other material possessing similar properties.
