ABSTRACT:
A valve particularly for controlling the admission of fluid to sectional nozzles of a turbine has a slidable valve sleeve provided with a control face. The valve sleeve is surrounded by a stack of valve rings fixedly held in the sequentially housing. Each valve ring has a circumferentially extending axial extension with which it engages an adjoining valve ring of the stack. Each axial extension has at least one discontinuity to define a port between any two valve rings. Ports associated with different valve rings communicate with different nozzle sections. As the valve sleeve is moved in one direction, its control face equentially opens the valve ports associated with the different nozzle sections.
