A processor for controlling operation of a central tire inflation system (CTIS) to change a tire pressure of a tire of a vehicle is configured to control the CTIS to inflate or deflate the tire to a predetermined tire pressure which is above a target tire pressure for the tire. The processor then controls the CTIS to deflate the tire until the target tire pressure is reached. In this manner, a second tire inflation operation to achieve the target tire pressure in the tire can be avoided.

Central tire inflation system

A filter device for a conduit includes a gas-permeable pre-filter element and a gas-permeable, liquid-impermeable filter element. The filter device is configured to be fluidly coupled to a conduit such that a gas can flow, in sequence, through the pre-filter element, the filter element and then the conduit. The filter device can be used in each of a vehicle hollow driveshaft and a hollow wheel stub axle forming a CV joint having a compressed air supply line which passes therethrough. Compressed air can be supplied via the air supply line without the need for an additional fluid transfer device fluidly connecting the driveshaft and the stub axle's conduits.

Filter device

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

A vehicle wheel assembly () for supplying compressed air from a vehicle axle to a tire () comprises a vehicle wheel () and a control valve assembly (). The wheel () comprises a wheel hub () for mounting the wheel () to a vehicle (V); and a wheel rim for mounting a tire () on the wheel (). A transfer line () is provided in the wheel for transferring compressed air from the wheel hub to the wheel rim () for inflating the tire (). The control valve assembly () comprises an inlet, an outlet and a control valve () operably located between the inlet and the outlet for controlling passage of compressed air between the inlet and the outlet. The control valve assembly () is removably disposed in the wheel hub () such that fluid communication is established between the control valve assembly () and the transfer line ().

Vehicle wheel assembly

A gaiter () for a lubricated joint () comprises a sidewall structure () defining an enclosure () for receiving a lubricant and a passageway () for conveying a gas. In use, the passageway () conveys gas in isolation from said enclosure (). Gaiters () in accordance with the invention find application in vehicle central tire inflation systems (CTIS).
