Abstract: A double acting pump mechanism is described for mounting on a wheel for inflating a pneumatic tire. The double acting pump mechanism includes a housing having a first pump chamber and a second pump chamber; wherein a diaphragm separates the first pump chamber from the second pump chamber; the housing further including an inlet port in fluid communication with the first pump chamber, and an outlet port in fluid communication with the second pump chamber, and wherein the outlet of the first pump chamber is in fluid communication with the inlet of the second pump chamber; a striker plate is positioned for reciprocation in the housing; the striker plate being connected to a diaphragm holder, wherein the diaphragm holder engages the diaphragm and actuates the diaphragm in the first and second pump chamber. Preferably the striker plate is actuated by a permanent or electro magnet mounted on a stationary part, or the striker plate is actuated by an electrically driven magnet.

Abstract: An air maintenance tire assembly having an elongate air pumping sidewall air passageway includes an inlet air passage screw assembly inserted through a tire sidewall profiled bore to conduct air from outside the tire into a regulator positioned within a tire cavity. The screw assembly includes a screw body having at an outer end a large-diameter filter housing, a smaller-diameter midsection shank portion, and an inner large-diameter valve housing connecting to the regulator within the tire cavity. A valve mechanism seats within the valve housing and moves between an open position conducting air from the screw body into the regulator assembly and a closed position preventing a backflow of air from the regulator assembly.

Abstract: A control valve suitable for use with a tire and pump assembly is described that controls the flow of air from the pump into the tire. The control valve includes an optional bi-directional feature. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

Abstract: A device (10) is disclosed for providing air to a tire 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 tire and which is configured to provide, when activated, air under pressure to the tire. 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 tire and a body (40) which rotates in unison with the rod (56) while 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 tire. Rotation of the body (40) is superimposed on rotation of the pump with the tire. 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).

Abstract: A connection assembly for an air maintenance tire system is provided. The air maintenance tire system includes an annular air tube, a valve housing and at least one connecting tube that is in fluid communication with the annular air tube and the valve housing. The connection assembly includes a connection housing that in turn includes a first port, a second port and a fluid passageway extending between the first port and the second port. A first compression fitting fluidly connects the annular air tube to the connection housing first port and a second compression fitting fluidly connects the connecting tube to the connection housing second port. The connection assembly enables a secure connection and fluid communication between the annular air tube and the connecting tube.

Abstract: A pumping assembly for maintaining a pneumatic tires inflation pressure is described. The pumping assembly includes at least one double chamber pump connected to a cam. The cam is connected to a gravity mass to maintain the cam in a stationary position. The pump has a roller for engaging the cam and producing the pumping action as the tire rim rotates. The assembly is preferably mounted in a reservoir wherein the reservoir is in fluid communication with one or more tire cavities. The system requires no alteration to the tire and pumps the air directly into the valve stem. The pumps are configured to provide an amplication effect because of the way they are configured, and thus do not need high compression ratios.

Abstract: A wheel hub arrangement having a wheel hub for mounting a rim with an inflated tire. The wheel hub arrangement has a rotary piston compressor mounted rotatably on the wheel hub. The wheel hub arrangement has a switchable mechanical coupling device, by way of which the rotary piston compressor can be switched over between a compression mode, in which the rotary piston compressor can be actuated by way of a rotational movement relative to the mounted rim or the wheel hub, and a rest mode, in which it is passive and does not produce any compressed air on the outlet side, and the rotary piston compressor producing compressed air on the outlet side for filling the tire in the compression mode.

Abstract: A system is used with a pneumatic tire mounted on a wheel rim to keep the pneumatic tire from becoming underinflated. The first system includes a plurality of pumps attached circumferentially to the wheel rim, each pump having pump parameters, and a control valve for controlling inlet air into a tire cavity of the pneumatic tire. The control valve has valve parameters. The system predicts system performance under various configurations and conditions through use of the pump parameters and the valve parameters.

Abstract: A device for controlling tire pressure is disclosed which comprises a pump (28) having opposed pistons (30) which reciprocate in cylinders (40) carried by a casing (38). The pistons (30) are at the outer ends of rings (50) which are themselves fitted to an eccentric (26). The eccentric (26) is integral with a clutch plate (24). A second clutch plate (22) is fixed to a non-rotating axle (18) which itself forms part of a hanging counterweight structure (20). A piston (84) pushes the eccentric and clutch plate (26, 24) against the clutch plate (22) thereby to prevent the eccentric (26) from rotating with the rings (50) upon a sensor detecting that a tire has a low pressure in it. Stopping the eccentric initiates the pumping action of the pistons (30).
