Embodiment Construction

[0046] Referring to FIGS. 1 and 5 , the tire assembly 10 includes a tire 12 , a reversible peristaltic pump assembly 14 and a tire rim 16 . The tire is mounted to a pair of rim mounting surfaces 18 , 20 adjacent outer rim flanges 22 , 24 in a conventional manner. The outer rim flanges 22 , 24 have an outer rim surface 26 . As shown, the annular rim body 28 connects the rim flanges 22, 24 and supports the tire assembly. The tire is of conventional construction having a pair of sidewalls 30 , 32 extending from opposing bead regions 34 , 36 to a crown or tire tread region 38 . The tire and rim enclose the tire cavity 40 .

[0047] As shown in Figures 1, 2 and 3, the peristaltic pump assembly 14 comprises a pump 41 mounted in a passageway 43 in the sidewall region of the tire, preferably adjacent to the bead region. This air channel 43 may be molded into the sidewall of the tire during the vulcanization process or during the molding process after vulcanization hardening. The p...

Abstract

A pressure regulator device (54) for a tire is proposed. The pressure regulator device comprises a regulator body (70) and a cap (120) connected to the regulator body, wherein the regulator body is connected to a duct (72)having a first end, and a second end connected to a chamber (80) formed between the cap and the regulator body; a flexible ring (90) mounted in the chamber and having one or more slots (98); and a pressure membrane (104)mounted over the flexible ring. The regulator body further comprises an inlet port for fluid communication with an outlet of end of an air tube or an air passageway and the chamber (80), an outlet port for fluid communication with the chamber (80) and an inlet end of an air tube or an air passageway, and an ambient air inlet in fluid communication with the chamber (80) and the pressure membrane (104). The flexible ring is positioned to seal the inlet port of the regulator body. The cap has a flanged portion about a recessed chamber. The flanged portion is positioned for sealing engagement with the pressure membrane. The recessed chamber is in fluid communication with the outlet port of the regulator body.

Description

technical field [0001] The present invention relates generally to self-inflating tires, and more particularly to pump mechanisms and pressure regulators for these tires. Background technique [0002] Normal air diffusion reduces tire pressure over time. The natural state of a tire is when it is inflated. As a result, the driver must repeatedly act to maintain tire pressure or experience reduced fuel economy, reduced tire life, and reduced vehicle braking and handling performance. Tire pressure monitoring systems have been proposed to alert the driver when tire pressure is significantly low. However, such systems still rely on remedial action being taken by the driver when the driver is alerted to re-inflate the tire to the recommended pressure. Accordingly, it would be desirable to incorporate a self-inflating feature into the tire that would allow the tire to self-inflate to compensate for any decrease in tire pressure over time without driver intervention.
