Abstract

Oil Pump 1 is enclosed within sump 2 and connected to oil bath 3 via a conduit 4 and filtering apparatus 5. Filtering apparatus 5 includes stationary drum 6, rotatable screen 7, stationary scraper blade 8 and screen cleaning nozzles 9. Screen 7 is spring mounted on an axle within the drum 6 to enable close coupling of the screen 7 to the drum, and also enable the screen to have only minimal resistance to rotation. The screen 7 may be driven in any manner which maintains a substantially constant rotary speed for the screen.

Filter for Removing Debris from an Oil Bath

Oil Pump 1 is enclosed within sump 2 and connected to oil bath 3 via a conduit 4 and filtering apparatus 5. Filtering apparatus 5 includes stationary drum 6, rotatable screen 7, stationary scraper blade 8 and screen cleaning nozzles 9. Screen 7 is spring mounted on an axle within the drum 6 to enable close coupling of the screen 7 to the drum, and also enable the screen to have only minimal resistance to rotation. The screen 7 may be driven in any manner which maintains a substantially constant rotary speed for the screen.

Debris in the oil is collected on the screen 7 as the oil flows through the screen 7 into the drum 6 and through the conduit 4 into the sump 2. The scraper blade 8 removes debris from the screen 7 as it rotates past the blade. Any debris not removed by the scraper blade 8 is washed off the screen by a fine oil spray from the screen cleaning nozzles.

The debris removed by the scraper blade 8 and nozzles 9 is deposited on the trough 10 for removal from the bath area.
