摘要： A pneumatic valve, including a valve housing with an air chamber with one or more air ports. A respective air port of at least one of the air ports can be opened and closed by a movable valve flap which is mechanically coupled to a shape memory alloy. The SMA element deforms as a result of supplying electrical heating current and effects a predefined movement of the valve flap for opening or closing the respective air port. The deformation of the SMA element is reversed when the supply of the electrical heating current ends. The valve flap has a leaf spring. The leaf spring is held rotationally fixedly relative to the valve housing. The leaf spring interacts with the SMA element such that a stroke of the SMA element caused by the deformation is converted into a stroke of the valve flap by elastic bending of the leaf spring.

摘要： A pneumatic solenoid valve, comprising an electromagnetic actuator and an air chamber with multiple air connections configured to be connected with the interposition of the air chamber via multiple switching positions of the magnetic actuator is disclosed. The actuator is configured to assume three different switching positions by energizing the actuator in a unipolar manner with three different current intensities and to move first and second sealing element via an actuation mechanism when switching between the switching positions. In a first position, a first sealing element closes a first air connection, and a second sealing element releases a second air connection. In a second switching position, the first sealing element closes the first air connection, and the second sealing element closes the second air connection. In a third switching position, the first sealing element releases the first air connection, and the second sealing element closes the second air connection.

摘要： A pneumatic valve comprises an actuator with a movable closing element being disposed in a housing; the closing element with a tappet penetrating an actuator opening between an air chamber formed in the housing and an actuator chamber, and a plate, with a sealing element, for closing the supply opening, thereon, on that end of said tappet protruding into the air chamber, and an elastic element pressing the plate toward the actuator opening in an activated state; the actuator element configured to move, in a non-energized state, the activating element to press the tappet against a supply opening, and in an energized state to move the activating element so as not to exert force on the tappet so that the plate is pressed in the direction of the actuator opening by the elastic element. A sealing collar disposed about the tappet seals the air chamber from the actuator chamber.

摘要： A method for operating a vehicle including at least one device, in which the one device is altered from a first state to a second state by an electronic computing device of the vehicle. The electronic computing device ascertains a present time and automatically alters the device from the first state to the second state on the basis of the ascertained time. Provision is made for the second state to be ascertained automatically by the electronic computing device from the first state.

摘要： A pneumatic valve, includes an air chamber with a supply port to supply compressed air into the air chamber and one or more discharge ports for discharging compressed air from the air chamber. An actuator with a movable closing element and a shape memory alloy SMA element are provided in the valve. The SMA element deforms in response to a supply of electrical heating current and effects an activation of the actuator by movement of the closing element. When the actuator is in an activated state, the closing element blocks the supply of compressed air via the supply port is blocked. When the actuator is in a deactivated state, the closing element enables the supply of compressed air via the supply port. Upon deactivation of the actuator, the closing element is moved by a restoring force into the free setting. The valve includes a check valve with an elastic element.

摘要： A device for pneumatically adjusting a seat in a transport vehicle, in particular in a motor vehicle, including one or more adjusting devices, each of which includes a pneumatic actuating device for adjusting the seat by generating pneumatic pressure, and including a trigger device, which the actuating device is switched from a standby state to an active state in response to a trigger signal when the device is being operated. The pneumatic actuating device brings about an adjustment of the seat in the active state. The pneumatic actuating device is designed such that the actuating device is mechanically preloaded in the standby state, and the mechanical preload is released in the active state in order to thus bring about the adjustment of the seat.

摘要： The invention relates to a method for monitoring the pressure in a device for the pneumatic adjustment of a seat in a transportation means, in particular in a motor vehicle. The device comprises a plurality of cushions (101, 102, . . . , 105) which are able to be filled with air and which are connected via respective valves (201, 202, . . . , 205) to a common preliminary pressure volume (3), wherein a pressure sensor (4) is provided for measuring the pressure (p) in the preliminary pressure volume (3) and the preliminary pressure volume (3) is coupled to a compressor (6) for supplying compressed air without a non-return valve being connected therebetween. For the purpose of monitoring the pressure in a respective cushion (101, 102, . . . , 105), a predefined pressure is set in the preliminary pressure volume by way of operation of the compressor (6) and/or by way of air discharge from the preliminary pressure volume (3) via at least one leak, with the valve (201, 202, . . . , 205) between the respective cushion (101, 102, . . . , 105) and the preliminary pressure volume (3) closed, wherein the predefined pressure deviates from a target pressure (p1, p2, . . . , p5) in the respective cushion (101, 102, . . . , 105) by at most 10% of the target pressure and/or at most 50 hPa. After the setting of the predefined pressure, the valve (101, 102, . . . , 105) between the respective cushion (101, 102, . . . , 105) and the preliminary pressure volume (3) is opened and the pressure in the preliminary pressure volume (3) is measured via the pressure sensor (4). If the measured pressure (p) deviates from the target pressure (p1, p2, . . . , p5), the measured pressure (p) is set to the target pressure (p1, p2, . . . , p5) by way of operation of the compressor (6) and/or by way of air discharge from the preliminary pressure volume (3) via the at least one leak.

摘要： A pneumatic valve, includes an air chamber, a connector for supplying compressed air to the air chamber and one or more connectors for discharging compressed air from the air chamber. The valve includes an actuator with a mobile closure element which, when the actuator is activated, blocks the supply of compressed air via the supply connector, and when the actuator is deactivated, is arranged to permit the supply of compressed air via the supply connector. The actuator is configured such that the closure element, on deactivation of the actuator, is moved by a restoring force into the free position. A check valve with a spring is arranged at the supply connector. The elastic force of the spring in the free position of the closure element prevents back-flow of compressed air from the air chamber into the supply connector when there is no supply of compressed air at the supply connector.
