Patent ID: 7323103

Claim:
A multi-valve device ( 1 ), for connection to a filter body or removable filter body ( 2 ) in a hydraulic circuit, preferably a lubrication assembly, comprising an oilpan, said multi-valve device ( 1 ) comprising: a first valve ( 3 ) for closing the oil intake in the filter with a view to dismantle the filter; a second bypass valve ( 4 ) that opens when the filter is blocked; a third valve ( 5 ) that opens in the event of excess pressure in the hydraulic circuit; wherein the valves ( 3 , 4 , 5 ) can be moved along one single and common axis of alignment ( 20 ) in the multi-valve device ( 1 ), the latter being machined en bloc from an intermediate part that is distinct from the oilpan, said intermediate part being located in a single concentric housing machined in the oilpan so that a symmetry axis ( 20 ) of the filter body ( 2 ) is identical to the above-mentioned axis of alignment.
