An impulse turbine comprises at least one runner keyed to a drive shaft in association with a distributor unit which has, for each runner, a circular outlet for the supply of fluid from the distributor unit to the blades of a respective runner. Each outlet is arranged coaxially inside the respective runner and the distributor unit is shaped in a manner such as to define a substantially circular path for the fluid and to cause the fluid to emerge from the distributor unit through the at least one outlet predominantly tangentially relative to the outlet.
