    CPC classification number: B60C23/003

    Abstract: A method of inflating and deflating a tire on a vehicle, said vehicle having a rotatable air passage connectable to a tire and a non rotatable air passage through which air is conducted from a pressurized air supply. One of the passages has an associated sealing means for co-operating with a contact component associated with the other passage and wherein prior to inflation and deflation of the tire, one of the passages is pressurized to ensure the integrity of the sealing means with the contact component.

    Abstract: A heavy-duty vehicle brake hardware mounting component that includes an integrated axle vent system and optional air supply line connector. The brake hardware mounting component includes a body with a central opening disposed around and rigidly attached to an axle of the vehicle. An annular groove is formed within the central opening and is in fluid communication with an axle opening. The air supply line connector is attached within an opening formed in the body and extends through the groove and into the axle opening, and enables attachment of and fluid communication between components of a tire inflation system within the axle and an external air source. Pressurized air from within the axle can flow through the axle opening, around the air supply line connector, through the annular groove, through a check valve in fluid communication with the groove, and to atmosphere to relieve air pressure build-up within the axle.

    Abstract: An air supply system on a vehicle for inflating and deflating a tire. The system includes a compressor connected to a drier having drying material to extract water from the air and a deflation line connectable between the tire and the dryer. The air dryer is operable in a first mode in which air passing through the dryer in a first direction is dried by the dryer and a second regeneration mode in which air passes through the dryer in a direction opposite to the first to remove water collected by the dryer, characterized in that the air used for the regeneration is air deflated from the tire.

    Abstract: A vented gaiter (6) for mounting to a shaft (4) comprises: a rim (34) defining an opening (33) for receiving the shaft (4); and a separate venting element (40). The venting element (40) is disposed within said opening (33). The shaft (4) is received in the opening (33), and the rim (34) is mounted to the shaft by means of a circular clamp (22). The venting element (40) is thus retained in place between the shaft (4) and the rim (34) and allows any air accumulated inside a CV joint enclosure (28) formed by the gaiter (6) when the gaiter (6) is mounted to the shaft (4) to vent axially according to a direction substantially parallel to the shaft longitudinal axis. The venting element (40) comprises a gas-permeable liquid-impermeable membrane (41).
