Abstract
A wheel service machine for a wheel having a rim and a tire includes a motor-driven shaft for supporting the wheel in rotation. The machine includes an abutment element integral with the shaft, a locking member for locking the rim against the abutment element, an engagement element movable to drive the locking member towards the abutment element, and a pneumatic actuator having a first and a second chamber rotating with the shaft and connected to the engagement element to move the engagement element automatically. The machine also includes a high-pressure source, a pneumatic circuit to selectively connect the first and second chambers of the actuator to the high-pressure source. The pneumatic circuit includes a rotary manifold having a first and a second duct, and a retaining valve configured to determine a difference in pressure between the second chamber of the pneumatic actuator and the second duct of the rotary manifold.
