Claims (1)

до упора в стопорное кольцо 7 и при возрастании давлени  жидкости сверх допустимого вследствие того, что наружный диаметр втулки 5, равный диаметру большей ступени дифференциального поршн , больше диаметра седла, запорный орган 3 под действием давлени  жидкости отходит вправо, при этом жидкость поступает в полость 9, соедипеппую полостью всасывани  гидромашины. Формула изобретени  Предохранительный кланан, преимущественно дл  реверсивных гидравлических машин , в корпусе которого упруго установлен запорный орган, жестко св занный с дифференциальным поршнем и взаимодействуюи;ий с седлом, отличающийс  тем, что, с целью упрощени  конструкции, на меньшей ступени дифференциального поршн  установлена втулка, наружный диаметр которой равен диаметру большей ступени дифференциального поршн , причем величина перемещени  указанной втулки ограничена с одной стороны упором в корпус, с другой - упором в дифференциальный поршень, а диаметр седла больше диаметра меньшей и меньше диаметра большей ступени дифференциального поршн .up to the stop into the locking ring 7 and with increasing fluid pressure above the allowable one, because the outer diameter of the sleeve 5, equal to the diameter of the larger differential piston stage, is larger than the diameter of the saddle, the locking member 3 moves to the right under the pressure of the fluid, and the fluid enters the cavity 9 suction cavity by suction of a hydraulic machine. Claims of the invention: A safety clan, mainly for reversible hydraulic machines, in the case of which a stop valve is rigidly mounted, rigidly connected to the differential piston and interacting with the seat, characterized in that, in order to simplify the design, a sleeve is installed at a lower stage of the differential piston, the outer diameter of which is equal to the diameter of the larger differential piston stage, and the amount of movement of said sleeve is limited on one side by the abutment into the housing, on the other by the abutment in the differential piston, and the diameter of the seat is larger than the smaller diameter and smaller than the diameter of the larger differential piston stage.
