Abstract
The invention relates to a device for assembling stacked annular filtering elements under constant pressure. The device comprises a support which provides an abutment for one end of the stack of filtering elements, a presser member which provides an abutment for the other end of the stack, and a calibrated spring which biases the presser member towards the support while trapping the stack of elements between the two abutments. The device is useful for the manufacture of filters used particularly for the filtration of oils.
Claims11
A device for the assembly of stacked annular filtering elements under constant pressure for filtering a fluid flowing through the stack of elements from the outside thereof to the inside thereof, the device comprising a support which provides an abutment for one end of the stack of elements, a presser member which provides an abutment for the other end of the stack of elements, and a calibrated spring acting to bias the presser member towards the support such that said abutments are pushed one towards the other thus trapping the stack of elements therebetween, said spring being housed inside a tube located inside the stack of elements, one end of the tube being connected to the presser member and the other end of the tube being mounted to slide in a sealed manner on a securing member connected to the support, whereby the spring cannot contact the filtered fluid leaving the inside of the stack of elements.
