  • Patent number: 8293104
    Abstract: Filtration systems may comprise a manifold having a fitting and a filter having a fitting. One of the manifold fitting and the filter fitting may comprise a nozzle including a tip portion having a contact surface. The other of the manifold fitting and the filter fitting may comprise a receptacle which receives the nozzle and has a contact surface. The filter may be removably mountable to the manifold with the filter fitting detachably engaging the manifold fitting and the contact surface at the tip portion of the nozzle abutting and sealing against the contact surface of the receptacle to prevent leakage at the end of the nozzle.
    Type: Grant

  • Patent number: 7807055
    Abstract: Filtration systems may comprise a manifold, a filter, a carriage, and a mounting mechanism. The manifold and the filter may each include an inlet fitting and an outlet fitting. The carriage may support the filter with the fittings of the manifold and filter respectively axially aligned. The mounting mechanism may be arranged between the manifold and the carriage to move the carriage and the filter between a disengaged position in which the filter fittings are spaced from the manifold fittings and an engaged position in which the filter fittings respectively engage the manifold fittings.

  • Patent number: 7338599
    Abstract: A filtration system comprising a manifold and a filter having fittings, wherein a carriage supporting the filter is operatively associated with a mounting mechanism to move the fitter between a position in which the filter is spaced from the manifold and a position in which a fitting of the filter engages a fitting of the manifold. The mounting mechanism includes a pivotable lever arrangement. The pivotable lever arrangement includes a lever, a pivot pin, and a pin and slot assembly. The lever pivots about the pivot pin and the pin of the pin and slot assembly slides between a first location and a second location in the slot.
