フィルター
Document Type and Number:
Japanese Patent JP4011620
Kind Code:
B2
Abstract:
The invention relates to a spin-on filter for filtering a flowing substance, especially to a filter for hydraulic liquid or lubricating oil in combustion motors. The filter comprises a casing, which is openable at one end, a substantially cylindrical replaceable filter means fitted inside the casing, the flow to be filtered having been arranged to pass through the filter means mantle, and a collar for connecting the filter with a device assembly, which includes inlet and outlet ducts for flow to be filtered. In accordance with the invention, the filter comprises a support member forming a solid extension of the collar, consisting of an axial spindle inside the filter means and of an end flange at its end opposite to the collar, the periphery of the end flange being tightly sealed against the inner wall of the casing such that the support member will receive the internal pressure within the casing axially. The joints between the support member and the collar, and the collar and the device assembly, respectively, may consist of threaded joints. As the flow to be filtered passes from the outside to the inside of the filter means, the means may bear against a perforated support pipe extending inside the means from the collar to the end flange of the support member.
