  • Fluid intake screening device
    Patent number: 4640771
    Abstract: A fluid intake screening device (10) is installed in a case (12) defining a sump (14), an opening (20), and an intake passage (28). A tubular baffle member (36) extends from the opening (20) into the sump (14), supports a tubular filter assembly (34) within it, and defines a chamber (52) therebetween. The baffle member (36) has a slot (54) for controllably directing fluid from the sump (14) to the chamber (52). An indexing apparatus (56) positions the slot (54) of the baffle member (36) and adjacent the bottom of the sump (14) and minimizes fluid aeration and turbulence with low fluid levels. A closure apparatus (38) can be removed from the case (12) to permit servicing of the filter assembly (34).
