  • 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: 5776342
    Abstract: A capsule type filter assembly provides increased strength by fixing ends caps of a filter element to a housing at both ends. At one end, a tubular part extends through a hole in the housing and is joined to the housing. An inner space of the tubular part communicates with the inner space of the filter element. In this configuration, the structural strength of the filter housing is enhanced by making the integrated body of the end caps and the filter element function as the reinforcing means for the housing.
