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.
