  • Patent number: 12225842
    Abstract: An apparatus for mowing grass. The apparatus has a plurality of cutting devices for mowing the grass. The apparatus has a plurality of carrying arms which are arranged offset with respect to one another with regard to the transverse axis of the apparatus, and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices. The apparatus has a plurality of supporting elements which support in each case one of the plurality of carrying arms on an underlying surface, and are arranged in front of the respective cutting device with regard to a forward moving direction of the apparatus. The apparatus can have the advantage that the leading supporting elements do not push any cuttings in front of them, and a risk of the apparatus being jacked up is decreased.

  • Publication number: 20220151142
    Abstract: The invention relates to an apparatus (10), preferably an autonomous robot apparatus, for mowing grass. The apparatus (10) has a plurality of cutting devices (20) for mowing the grass. The apparatus (10) has a plurality of carrying arms (22) which are arranged offset with respect to one another with regard to the transverse axis of the apparatus (10), and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices (20). The apparatus (10) has a plurality of supporting elements (24) which support in each case one of the plurality of carrying arms (22) on an underlying surface, and are arranged in front of the respective cutting device (20) with regard to a forward moving direction (V) of the apparatus (10). The apparatus (10) can have the advantage that the leading supporting elements (24) do not push any cuttings in front of them, and a risk of the apparatus (10) being jacked up is decreased.

  • Patent number: 10302202
    Abstract: A valve assembly for modulating flow of a fluid through a valve may include a plunger, a flange with an orifice, a first disc with an orifice, a second disc, a gasket in contact with both the flange and the first disc, three bearing members disposed between the first disc and the flange. The three bearing members define a position and orientation of the first disc with respect to the flange, and separate the first disc from the flange, thereby defining a gap between the flange and said disc. The plunger displaces the second disc surfaces from a first position to a second position.
