摘要： A reduced-pressure device includes a housing having recesses on sidewalls thereof, an air pressure storage unit and a compression unit. The air pressure storage unit is installed in the housing and comprises a pressure storage container, a piston assembly and a piston spring, and the compression unit is mounted on the piston assembly. The compression unit further includes a pressing element and a turntable. The pressing element is accommodatable in the recesses of the housing, and rotatable by the turntable in relative to the air pressure storage unit and the housing, and when the pressing element is pulled out of the recesses and rotated to a predetermined position to compress the piston assembly to produce a negative pressure in the pressure storage container, the pressing element can be rotated back to the original position to be accommodated in the recesses again after using.

摘要： An apparatus for regulating air pressure level in a tire is provided. The apparatus includes a housing attached to the tire; a piston located inside the housing, coupled to the housing via a spring; a one-way valve; and locking elements located at a specified location along the housing, wherein the piston is configured to move towards a first end of the housing responsive to an imbalance between centrifugal force applied to the piston due to angular speed of the tire and force applied to it by the spring, wherein the locking elements are configured to lock the piston at the specified location whenever the tire reaches a predefined angular speed, and release the piston once the angular speed of the tire crosses a predefined threshold, so that the piston moves towards a second end of the sleeve producing an air pulse, conveyed by the one-way valve into the tire.

摘要： This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The housing includes an air inlet and an air outlet. At least one of the flat plates includes, in at least one of an upper surface and a lower surface thereof, a plurality of guide portions each of which is a protruding portion or recessed portion arranged to extend in a radial direction. An air flow traveling radially outward is generated between the flat plates by viscous drag of surfaces of the flat plates and a centrifugal force. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly.

摘要： A device (10) is disclosed for providing air to a tyre which is mounted on a wheel rim which itself is free to rotate about a fixed, that is, non-rotatable axle 22. The device includes a pump (50, 52, 54, 62) which in use rotates with the tyre and which is configured to provide, when activated, air under pressure to the tyre. There is a pump drive system for activating the pump. The pump drive system comprising a piston rod (56) which is connected to and rotates with the tyre and a body (40) which rotates in unison with the rod (56) whilst the pump is inactive. An electric motor (68) rotates the body (40) with respect to the rod (56) to activate the pump and provide air to the tyre. Rotation of the body (40) is superimposed on rotation of the pump with the tyre. The device also includes a stator component (26) and coils (30) and magnets (32) for generating, by electrical induction, power for driving the motor using the relative rotation between the second part and the stator component (26).

摘要： An electroosmotic (EO) pump is provided that includes a housing having a pump cavity, a porous core medium and electrodes. The porous core medium is positioned within the pump cavity to form an exterior reservoir that extends at least partially about an exterior surface of the porous core medium. The porous core medium has an open inner chamber provided therein. The inner chamber represents an interior reservoir. The electrodes are positioned in the inner chamber and are positioned proximate the exterior surface. The electrodes induce flow of a fluid through the porous core medium between the interior and exterior reservoirs, wherein a gas is generated when the electrodes induce flow of the fluid. The housing has a fluid inlet to convey the fluid to one of the interior reservoir and the exterior reservoir. The housing has a fluid outlet to discharge the fluid from another of the interior reservoir and the exterior reservoir. The housing has a gas removal device to remove the gas from the pump cavity.
