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