Abstract: A rapid tire inflation plant comprising a low pressure high flow inflating gas source (2), an inflation device (DG), a motor (T), a compressor (C) driven by said motor and a control circuit arranged to control feed of low pressure inflating gas from said inflating gas source (2) to said compressor (C) and the feed of inflating gas at a relatively high flow and pressure to said inflation device (DG).

Abstract: A device for program-controlled variation of the composition of a gaseous mixture for inflating a tire for performing the method, comprising a first source of at least one main gas, a second source of at least one additional gas, at least one first compressor suitable for compressing to a preset pressure a gaseous mixture of at least said main gas and additional gas, at least one dispenser of compressed mixture which is connected to the delivery of said compressor, and further comprising at least one mixer for said at least one main gas and said at least one additional gas which is suitable for delivering a gaseous mixture having a desired composition, a gas analyzer means arranged downstream of said mixer, valve means for controlling the flow between said mixer and said first and second gas sources, and program control means arranged to control said valve means in response to control signals from said analyzer means.

Abstract: A tire changing machine having a support frame, rotatable supporting device for a wheel rim, locking device for securing the wheel rim to the supporting device, a fitting tool which can be secured to an adjustable tool supporting arm carried by the support frame, and driving device for the rotatatable supporting device. The machine also includes a first and a second pressure members which can be located in diametrically opposite positions with respect to a wheel rim carried by the supporting device and are designed to act on either side of a tire on the wheel rim, and drive device for actuating, upon control, each of the first and second pressure members.

Abstract: A tire changing machine which comprises: a bed, a frustoconical platform which is supported by the bed and is designed to act as a support for a wheel rim, a hollow shaft which is coaxial to, and rotates rigidly with, the frustoconical platform and raises from said platform and is provided with a threaded portion, a fixed shaft which is arranged within said hollow shaft and protrudes therefrom, securing means scewable onto the hollow shaft for fixing the wheel rim on the platform, a lateral column raising from the said bed, upper bead breaking means carried by the said column and arranged to act from above on a tire on a wheel rim located on the frustoconical platform, lower bead breaking means arranged to act from below on the lower side of a tire on a whell rim placed on the platform, a driving motor for rotating the said frustoconical platform about the said hollow shaft, and automatic locking and releasing means between the said driving motor and said platform to safely clamp the platform against a wheel

Abstract: A bead lifting lever having a curved body that ends with at least one tip provided with a rounded and expanded tip edge.

Abstract: A tire removing machine that comprises a lateral bead extractor formed by an arm that oscillates about a fixed vertical pivot or supports a bead extractor flap and by means for the actuation of the oscillating arm. The actuation means comprise an L-shaped lever that is pivoted about the fixed vertical pivot and has one arm that abuts against a stroke limiter on the oscillating arm and another arm that is provided with a cam follower roller, and an eccentric cam that slidingly engages the other arm of the L-shaped lever and is kinematically connected to a source of rotary motion, so that the rotation of the eccentric cam imparts, by means of the L-shaped lever, a controlled oscillating motion to the L-shaped lever.

Abstract: The tire removing machine has a resting base, a hollow support rigidly connected to the base and provided with a supporting flange for supporting motor vehicle wheels. A hollow securing shaft extends in the base and protrudes from the support, perpendicularly to the flange. A wheel centering and securing cone is anchored to the securing shaft outside the flange. A traction pin is rotatably accommodated in the shaft and extends beyond the centering cone where it ends in a traction head. A tool-holder bar with tool for mounting and removing a tire is at least temporarily coupled to the traction head.

Abstract: A mounting device for automative tires having a rotationally driven holder for gripping a wheel rim and a pressing device mounted on a stand for pressing the tire bead away from the horn of the wheel rim. The device has two arms guided by means of sliding bushings on a column so they can be moved laterally toward and away from each other. These arms are hinge connected at their rear ends to the sliding bushings so they can be pivoted by a motor drive. A pressure element that acts on the tire wall next to the horn of the wheel rim is mounted on the front free end of each arm. The two arms are designed so their length can be adjusted by telescoping. A linear drive whose adjustment element has a coupling element that automatically engages with the extensible inside part of the respective telescopic arm is mounted approximately in parallel above and below each telescopic arm.
