A PRESSURE RELIEF VALVE FOR AN INTERNAL COMBUSTION ENGINE LUBRICATION SYSTEM |
摘要 |
<p>A pressure relief valve for a lubrication system of an internal combustion engine includes a valve body disposed within a generally cylindrical bore in a housing. The valve body is axially movable within the bore and is provided with a sealing surface on one end. A spring biases the sealing surface against a valve seat in the housing. A guide, which is preferably sleeve-shaped, is non-fixedly arranged within the bore for guiding the axial movement of the valve body and reducing the impact of manufacturing tolerance variations on valve operation. In a preferred embodiment, the sealing surface of the valve body is spherically shaped and the valve seat is conically shaped. A vent passage is provided in the sleeve-shaped guide to equalize pressures within the bore during operation of the valve.</p> |
