Description

ABSTRACT:
This disclosure relates to a filter which includes a plastic housing and which has an intermediate filter screen. The peripheral portion of the screen is sealed between the two housing halves by flowing a portion of at least one of the housing halves through the screen and bonding that portion to the other housing half. Further, the housing has peripheral walls which are bonded to one another after partial assembly through an interference fit and a concentrated heating of the material of the housing halves.
