The harness connector includes a set of pins, where the first set of pins of the control box are configured to be connected to the set of pins included in the harness connector, and the control box is configured to determine a platform of the aircraft based on the presence or absence of a pin in the set of pins included in the harness connector.

A rotary fluid regulator (1) has a housing (2) with an intake opening (3), at least one outlet opening (4), and a hollow valve element (5) that is received rotatably in the housing (2) forming a fluid duct (6). An electromotive drive element (13) is provided and rotates the valve element (5). Rotation of the valve element (5) enables a fluidic connection between the intake opening (3) and at least one outlet opening (4) to be adjusted or blocked.

A device for forming at least part of a head part of a liquid treatment apparatus is arranged to receive a connecting head of a replaceable liquid treatment cartridge and includes at least one ratio-setting valve. The ratio-setting valve is provided with at least two first ports, each placeable in essentially sealed liquid communication with respective cartridge ports of a connecting head of a replaceable liquid treatment cartridge inserted into the device, and with at least one second port. The ratio-setting valve includes at least one movable regulating part for setting a volumetric flow rate ratio between a first flow of liquid between a first of the first ports and the at least one second port and a second flow of liquid between a second of the first ports and the at least one second port at any of a plurality of values.

A fluid transfer system (100) includes a transfer device (104) and an interface device (102). The transfer device (104) includes a fluid transfer member (164) and a transfer coupling member (125) to align the fluid transfer member (164) with the interface device (102). The interface device (102) includes a reservoir port (108), a fluid transfer member receptacle (144), an interface coupling member (124), and a reservoir valve (110). The interface coupling member (124) is configured to close the fluid transfer member receptacle (144) and to couple to the transfer coupling member (125) and open the fluid transfer member receptacle (144) to receive the fluid transfer member (164). The reservoir valve (110), e.g., a sliding seal, is configured to close the reservoir port (108) from the fluid transfer member receptacle (144) and to open the reservoir port (108) to the fluid transfer member (164) when the fluid transfer member (164) is positioned in the fluid transfer member receptacle (144). The fluid transfer member (164) can include a plunger assembly configured to open and close the reservoir port (108).

A compressor (10) for compressing air for a compressed air system of a motor vehicle has a cylinder housing (14) and a cylinder head (16) connected thereto. A compressor piston is moveable in oscillation up and down in a cylinder in the cylinder housing (14). A lamella (34, 36) is received in a depression (38) in an underside (30) of the cylinder head (16) facing the compressor piston. The delivery rate of the compressor (10) can be regulated by closing or opening a control channel (60, 60) in the cylinder head (16) via the lamella. A bearing end (44) of the lamella (34, 36) is hinged in a pivotably guided manner on a bearing contour (54) of this depression (38). As a result, a separate bearing journal for pivotable mounting of the lamella (34, 36) on the cylinder head (16) may be omitted.

A valve (1), in particular a vacuum valve, having at least one valve housing (2), at least one closure element (3), and at least one valve seat (4). The valve seat (4) surrounds at least one valve opening (5) of the valve (1), and the closure element (3) can be moved back and forth between at least one open position, in which the closure element (3) at least partly releases the valve opening (5), and a closed position, in which a sealing surface (8) of the closure element (3) is pressed against the valve seat (4) in order to close the valve opening (5), by at least one closure element drive (6, 7). At least one surface (9) of the valve (1) has an average surface roughness RZ less than or equal to 0.4 um, preferably less than or equal to 0.25 um.
