Abstract
A fluid filtration system, particularly for use in piston cooling jets, includes a fluid chamber with a filter element disposed therein. In one embodiment, the filter element comprises a tubular filter telescopically attached within a coil spring. In a second embodiment, the filter element comprises a coil spring serving as a filter. The filter element is installed within the fluid chamber, so its interior is in communication with one of an inlet and outlet of the chamber, by compressing the filter element and inserting it through an aperture in the fluid chamber which serves as the other of the fluid inlet and outlet. The filter element then expands and is held in place by its resilient bias. The filter element of the invention can be used to apply local filtration, and can be readily removed for cleaning or replacement by reversing the installation process.
