Reversing valve for a filter arrangement with at least two filter chambers

A filter arrangement, comprising

• first and second filter chambers in a filter housing;
• a reversing valve in fluid communication with said filter chambers and moveable between first and second positions for alternatively and selectively actuating said first and second filter chambers, respectively, said valve including a valve part rotatable about a rotary axis;
• a reversing lever coupled to said valve part for simultaneous rotation with said valve part about said rotary axis, said reversing lever having a first lever arm and a second lever arm forming a manually operable handle part and being pivotable relative to said valve part about a pivot axis perpendicular to said rotary axis;
• a compensation valve within said reversing valve controlling fluid pressure compensation between said filter chambers, said compensation valve being activated by pivoting of said reversing lever;
• and
• a detent device on said reversing lever movable between locking and release positions permitting and preventing rotation of said valve part respectively, by pivoting of said reversing lever, such that said compensation valve is activated when said detent device is moved to the release position.
