Beschreibung
Zusammenfassung:	FIELD: power engineering; steam turbines. SUBSTANCE: invention is designed for use in protection systems of steam turbines. Proposed device has steam housing and drive housing in which seat and guide bushing are press-fitted and which accommodate cup, spring-loaded piston with sealing bead and plate with mating sealing bead. Ring and underpiston chambers are formed in drive housing connected to oil line of power oil. Overpiston chamber is connected to drain oil line. Rod is installed in guide bushing and is loaded by second spring, and it connects plate and cup. Cylindrical recess is made in drive housing. Plate is provided with mating cylindrical projection getting into recess and it is connected with rod by spherical bearing. Differential piston spring rests on rod. Rod is furnished with spacer provided with bead. Clearance is left between bead and plate. EFFECT: improved reliability of device. 1 dwg
