PRESSURE REGULATOR Russian patent published in 1998 - IPC

FIELD: automatic control equipment, in particular, for water supply systems. SUBSTANCE: device has housing, input and output chambers, control member, which is located between them and is designed as locking member and saddle. In addition device has cylinder which is mounted on input chamber end and provides setting chamber with mating spring-loaded sensitive member which working surface is extended through hole in wall with saddle into output chamber and is connected to locking member which is shaped as disk. Goal of invention is achieved by design of sensitive member which provides action of input pressure to single small region of sensitive member used for compensation of errors caused by rigidity of spring. This also results in possibility of increased stability of operations and decreased travel of locking member due to increased saddle perimeter up to perimeter of effective circle of sensitive element with respect to output pressure. EFFECT: decreased weight and size, increased precision. 5 cl, 3 dwg
