Dana Corporation - Toledo OH

International Classification:

B01D 2708

US Classification:

210443

Abstract:

A high pressure spin-on filter cartridge utilizes an end plate which is strengthened by four substantially triangular shaped gussets which project from an annular U-shaped bridge that supports an internally threaded hub member. The internally threaded hub member provides an outlet for the filter cartridge while a plurality of radially positioned inlet openings are positioned between the gussets. The gussets extend radially past a sealing gasket that seals the spin-on filter canister with a machine on which it is mounted.

US Classification:

210168

Abstract:

An oil sump with an integral filter includes an upper sump having a major opening therethrough which contains the integral filter and a minor opening through which projects a tube which is connected to the inlet of a suction pump. Beneath the upper sump is a lower sump into which the tube projects and with which the opening with the filter is in communication. Both the upper sump and lower sump are made of a plastic material, such as a thermoplastic or thermosetting material, which includes enforcing fibers. A lower sump is fixed to the upper sump by either a strong permanent adhesive or by welding, using known welding processes such as ultrasonic welding, vibration welding or friction welding.

International Classification:

B01D 2710

US Classification:

210130

Abstract:

A sump pan for a device such as a transmission or engine lubricating system includes an upper chamber and a lower chamber which are separated by a partition. The partition has an opening therethrough in which a filter media is positioned for filtering dirty fluid in the upper chamber so that clean fluid collects in the lower chamber. A suction tube extends through the partition for pulling the clean fluid for recirculation through the device utilizing the fluid such as a transmission or an engine. A bypass valve is also disposed in the partition so that if the fluid becomes too viscous to pass through the filter media, or the filter media becomes clogged, the bypass valve will open so that the fluid can still circulate.
