  • Patent number: 12241440
    Abstract: A filtration system comprising a plurality of filters, in particular oil or fuel filters, a first operating element movable from a default position to a least one isolating position for isolating at one filter of a first group of filters from the filtration system and a second operating element movable from a default position to a least one isolating position for isolating at least one filter of a second group of filters from the filtration system. The filtration system comprises a mechanical blocking mechanism that is actuated by a movement of the first operating element out of its default position to block the second operating element in its default position and actuated by a movement of the second operating element out of its default position to block the first operating element in its default position.

  • Patent number: 11964565
    Abstract: The present disclosure discloses a trunnion mount for mounting an engine, in particular a combustion engine, to a chassis, comprising a support element rigidly connected and/or connectable to the engine having a ring portion with an outer bearing surface, which may be arranged concentrically around the crankshaft; a female support having an inner bearing surface for surrounding the bearing surface of the support element, the female support forming the link between the chassis and the engine; and a rubber bearing arranged between the inner bearing surface of the female support and the outer bearing surface of the support element. In one or more examples, the trunnion mount includes a rubber bearing that is directly vulcanized on at least one of the bearing surfaces and/or wherein the ring portion is formed as a separate element from a mounting portion of the support element and connectable thereto via axial screws.
