Abstract
The single-acting phase variator includes a piston actuator movable towards an actuate position, as a result of the admission of a pressurized fluid to a supply chamber through a distribution and discharge duct opening in the chamber against the force of a spring. A valve is provided in the variator for connecting the distribution and discharge duct alternatively to a feed duct for the pressurized fluid or to a discharge opening for the rapid discharge of the fluid from the chamber.
