Abstract

Described is a stream turbine with a shaft (3) which, at least over part of its length, is located in a housing (4) through which it passes, one end of the housing (4) being the high-pressure end (10) and the opposite end the steam-exhaust end (12). In addition, the housing incorporates a control valve (30) designed to control the rate of steam flow into the housing (4). The invention calls for the shaft bearings to be dry-running, this being achieved by using magnetic bearings (6, 8, 14) located inside the housing (4) at the high-pressure end (10) and at the steam-exhaust end (12). The invention also calls for the control-valve operation to be oil-free, this being achieved by using an electromagnetic actuator (28).
