FLUID-PRESSURE SYSTEM FOR CYCLIC LOADING OF BENCH FOR TESTING HIGH-PRESSURE HOSES Russian patent published in 2006 - IPC F15B19/00 

FIELD: testing fluid-pressure systems or apparatus.

SUBSTANCE: fluid-pressure system comprises pump connected with the controlled distributor connected with the fluid-pressure multiplicator. The under-piston space of the multiplicator is connected with the high-pressure hoses to be tested. The pump is connected with the inlet of the hose through the first check valve. The outlet of the hose is connected with the under-piston space of the multiplicator and with the first inlet of the controlled distributor through the first reduction valve. The pump is connected with the above-piston space of the multiplicator through the second reduction valve. The above-piston space is connected with the valve for control of operation pressure and with the second inlet of the controlled distributor through the second check valve. Both of the outlets of the distributor are connected with the tank.

EFFECT: enhanced reliability.
