conjoint control of vehicle sub-units of different type or different function, road vehicle drive control systems for purposes other than the control of a single sub-unit B60W) ## Abstract A valve device (110), in particular a throttle device, preferably for use in motor vehicles, the finished valve device (110) comprising a housing (120), which surrounds a flow duct portion (126, 128, 130, 133), and additionally comprising at least two valves (132, 134, 136, 137) accommodated on the housing (120) and movable relative thereto such that, by relative adjustment of the valves (132, 134, 136, 137) relative to the housing (120), the effective flow area of the flow duct portion (126, 128, 130, 133) may be modified, adjacent valves (132, 134, 136, 137) being produced separately and being couplable or coupled together for joint movement by interlocking geometries (164, 166). ## Claims ### Claim 1 A valve device comprising: a housing surrounding a flow duct portion; and at least two valves accommodated on the housing and movable relative thereto such that adjustment of the valves relative to the housing modifies the effective flow area of the flow duct portion; wherein adjacent valves of the at least two valves are produced separately and are couplable or coupled together for joint movement by interlocking geometries; wherein at least one of the at least two valves comprises: at least one valve shaft portion, with which the valve is rotatably supported on the housing; and a valve body, which is accommodated in the flow duct portion so as to modify the flow area; and wherein the at least one valve shaft portion is constructed in one piece with the valve body. ### Claim 2 (depends on 1) The valve device according to claim 1, wherein at least one of the at least two valves comprises two valve shaft portions that are substantially coaxial relative to the valve axis of the at least one valve; and wherein the valve body is provided axially between the two valve shaft portions. ### Claim 3 (depends on 1) The valve device according to claim 1, wherein one of two valve shaft portions connected to the valve body comprises a coupling geometry; wherein the respective other valve shaft portion comprises a counter coupling geometry; and wherein the coupling geometry and the counter coupling geometry are couplable in interlocking manner for joint rotational movement about the valve axis. ### Claim 4 (depends on 3) The valve device according to claim 3, wherein one geometry of the coupling geometry and counter coupling geometry comprises a recess; and wherein the respective other geometry comprises a torque-transmitting projection introducible into the recess. ### Claim 5 (depends on 3) The valve device according to claim 3, wherein the valve device comprises; an actuating element, which may be or is connected to at least one valve to introduce an actuating moment for relative rotation of the valves and the housing; wherein the actuating element comprises one geometry out of the coupling geometry and the counter coupling geometry. ### Claim 6 (depends on 1) The valve device according to claim 1, wherein in addition to the provided interlocking geometries, a plurality of individually produced valves are connected together operationally non-detachably. ### Claim 7 (depends on 1) A valve for a valve device according to claim 1. ### Claim 8 (depends on 1) The valve device according to claim 1, wherein the valve device is in the form of a throttle device for use in motor vehicles. ### Claim 9 (depends on 3) The valve device according to claim 3, wherein the coupling geometry is located at a free axial end of its respective valve shaft portion. ### Claim 10 (depends on 4) The valve device according to claim 4, wherein the torque-transmitting projection is complementary to at least one portion of the recess circumference. ### Claim 11 (depends on 6) The valve device according to claim 6, wherein the plurality of individually -produced valves are connected together operationally non-detachably by bonding. ### Claim 12 (depends on 6) The valve device according to claim 6, wherein the plurality of inidvidually produced valves are connected together operationally non-detachably by laser welding. ### Claim 13 (depends on 6) The valve device according to claim 6, wherein the plurality of individually produced valves are connected together operationally non-detachably by adhesion. ### Claim 14 (depends on 1) The valve device according to claim 1, wherein a rotational axis of at least one of the at least two valves is provided at a distance from the valve body of the valve; and wherein the valve body of the at least one of the at least two valves is shaped so as to fit closely or abut an inner wall surface of the housing in order to maximize the flow area of the flow duct portion when the valve is rotated to a fully open position.
