The invention relates to a device for the pneumatic adjustment of a seat in a means of transport, in particular in a motor vehicle, comprising one or more cushions (3) which can be filled with air and which are connected via one or more valves (1) to a compressed-air supply (2), and a control device for the actuation of the one or more valves (1) for the purposes of changing the filling state of the one or more cushions (3). The device according to the invention is characterized in that a respective valve (1) of at least some of the valves (1) comprises one or more actuation elements (4) composed of electroactive polymer, to which an electrical voltage can be applied. By application of the electrical voltage, a respective actuation element (4) is deformed, and in this way, one or more passage openings (6, 6) via which an exchange of compressed air with at least one cushion (3) takes place is or are opened up or shut off.

This circuit breaker (10) for a facility for handling pressurized fluid includes a male element (100) and a female element (200) intended to fit in one another. The male element includes a male body (102) defining a first inner pipe (104) and provided with a member for closing off the front end of the first pipe, along the fitting axis, of at least one first radial passage (116), of a movable valve (118) and a locking notch arranged on the male body. The female element includes a female body (202) defining a second inner pipe (204A) and provided with at least one radial passage (256), a movable valve (218) and several locking members (242) movable transversely with respect to the fitting axis, between a first radial position, for the axial locking of the male and female bodies in the coupled configuration, and a second radial position, where the locking members free the passage of the male body (102) in the female body (202). In the coupled configuration, the radial passages (116, 256) are in communication, while sealing gaskets (266, 268) respectively cooperate radially with the male and female bodies (102, 202). A resilient return ring (246) is mounted on the female body (202) and surrounds the locking members (242). This ring resiliently returns the locking members toward their first radial position in the coupled configuration and is deformed radially, and resiliently, by the locking members during their movement, from their first radial position toward their second radial position.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

A quick coupler includes a housing in which a first and a second coupler cartridge are received. The spaced-apart center axes of the first and second coupler cartridges each run parallel to a vertical axis such that the center axes are contained in a common reference plane. The quick coupler further includes a first actuating lever and a second actuating lever for actuating the coupler cartridges. First and a second axes of rotation of the respective first and second actuating levers are oriented perpendicularly to the reference plane, and a first actuating arm and a second actuating arm are arranged to perpendicularly to the reference plane on opposite sides of the housing.

An assembly for controlling fluid flow between a fluid source and an outlet includes an electrically operable valve interposed between the fluid source and the outlet, the valve being actuatable between an open position and and a closed position; and an activator device comprising (i) a user-activatable sensor configured to detect a stimulus when the stimulus enters a detection zone, (ii) a transmitter configured to transmit a signal upon activation of the sensor by a user to a controller for actuating the valve, and (iii) an orientation detector configured to detect among at least two orientations of the activator device. When the activator device is in a first orientation, a zone of detection of the sensor may extend no farther than a predetermined distance from the sensor, and when the activator is in a second orientation, the zone of detection may extend farther than the predetermined distance from the sensor.

The invention relates to a device for the pneumatic adjustment of a seat in a means of transport, in particular in a motor vehicle, comprising one or more cushions (3) which can be filled with air and which are connected via one or more valves (1) to a compressed-air supply (2), and a control device for the actuation of the one or more valves (1) for the purposes of changing the filling state of the one or more cushions (3). The device according to the invention is characterized in that a respective valve (1) of at least some of the valves (1) comprises one or more actuation elements (4) composed of electroactive polymer, to which an electrical voltage can be applied.
