Abstract: For a hydraulic system of a work vehicle, a fixed connector part fixedly arranged thereon. A fixed connector part has a plurality of hydraulic couplings. A hydraulic work system of a work equipment has hydraulic couplings which are either a movable part having a plurality of hydraulic couplings or a plurality of individual hydraulic connections, each having a hydraulic coupling. The movable connector part is connectable to the fixed connector part by a locking device. The hydraulic couplings of the fixed connector part are constructed to be hydraulically coupled to the hydraulic couplings of the movable connector part and alternatively to the hydraulic couplings of the plurality of individual hydraulic couplings.

Abstract: A method and a device for controlling a load sensing hydraulic system, having a bypass valve (F), which is controlled by a pump pressure (P) and which when the hydraulic system is in operation diverts a pump flow of hydraulic fluid to a tank (E). The bypass valve (F) is pre-stressed towards a closed position and is put on load by the pump pressure (P) towards an open position against the action of the pre-stress. When the hydraulic system operates in a idling operation a first pre-stress element (I) limits the pre-stress to a first pressure and upon activation of the hydraulic system, a pressure regulator (10) increases the pre-stress to a second, substantially higher pressure by applying a hydraulic, constant second pre-stress force, that is added to the first pre-stress force and is substantially greater than this.

Abstract: A dry powder inhaler (2) comprises a housing (6, 8) including a mouthpiece (10) and a cover (11, 12) movably mounted to the housing (6, 8). The cover (11, 12) is movable between an open configuration of the inhaler (2) in which the mouthpiece (10) is exposed for use and a closed configuration of the inhaler (2) in which the mouthpiece (10) is enclosed. In the open position, the cover (11, 12) at least partly defines an inlet aperture (71) to an inhalation air flow path leading through the inhaler (2) and communicating with the mouthpiece (10). The inlet aperture (71) is positioned in such a way that makes it difficult for a user to obstruct it when using the inhaler (2). Preferably, in the closed position, the mouthpiece (10) is received into the inlet aperture (71) to protect the mouthpiece (10) when the inhaler (2) is stored.
