  • Patent number: 11867298
    Abstract: Saturation of a secondary system pressure circuit (18) of a hydraulic system (4) of a motor vehicle transmission is earlier, in that an excess amount of oil from a primary system pressure circuit (16) of the hydraulic system (4) is not directed to a suction charging (40), but rather into the secondary system pressure circuit (18). This can take place via a system pressure valve (9) for the primary system pressure circuit (16), which is configured for this function.

  • Patent number: 11690189
    Abstract: A fluid measuring or fluid control device has a housing the housing parts of which are fastened to each other by at least one screwed connection, in which a screw engages through an opening in a peripheral wall of the first housing part and is screwed into a threaded opening in the second housing part. An elastic seal is arranged between the housing parts. The first housing part has a first resting face, and the second housing part has a second resting face which are both in peripherally circumferential contact with the seal. The screw shank and an edge of the opening have cooperating frustoconical surfaces which are oriented such that the second housing part is displaced in the direction towards the first housing part when the screw is screwed into the threaded opening, the resting faces coming into contact with the seal.
