AUTOMATIC HYDRAULIC SYSTEM FOR FLUID SUPPLY Russian patent published in 2005 - IPC

FIELD: hydraulics or pneumatics.

SUBSTANCE: automatic hydraulic system comprises centralized source of fluid and several consumers divided into sections in which at least one of the sections is connected with the source for pressure and drain pipelines provided with the remote controllable stop valve and pneumohydraulic accumulator and pressure gauge connected to the pressure pipeline between the valve and consumers. The pressure gauge is connected with the stop valve through the time delay circuit, indicator of pressure drop in the corresponding section of the hydraulic system, and time delay circuit through the member for opening the valve in the closed position of the member. The output of the time delay member is connected with the alarm signaling system and output of the circuit for closing the valve.

EFFECT: enhanced reliability.
