<p>A quick change oil filter assembly for installation and removal of an oil filter (5) on an engine without tools, skills or adjustments. A toggle action tightening band (30) has two positions. In an open position the band (30) is captive on the flange (7) of a filter support plate (1) with engine oil connections. A filter (5) with a base flange (6) is freely inserted or removed from the support plate (1). In the closed position, the band (30) engages the flange (6) on the filter base and draws it down against the flange (7) of the support plate, compressing a sealing gasket (8) between the flanges with a preset force. The tightening force is derived from inclined plane action of a sloping surface (14) on the band engaging a sloping surface (9) on flange (7) as the band diameter is reduced by the closing of the toggle lever (15). The toggle action of the closure ensures reproducible tightening forces to ensure leak proof sealing without adjustment. The band is segmented to enhance operation.</p> |
