Abstract

1,212,664. Hydraulic motor control circuits. SCHWERMASCHINENBAU NOBAS NORDHAUSEN VEB. Jan. 21, 1969, No.3398/69. Heading F1P. A combining valve 9 is switched from an open position I in which it connects together two hydraulic pressure supply pipes 10 each leading to an individual load in a hydraulic circuit (not shown) to a closed position II in which valve 9 isolates pipes 10 by means of hydraulically actuated switch valves 3, 4 controlled by fluid delivered by a pump I through control valves 14, 15 and lines 5<SP>1</SP> , 6<SP>1</SP>. Each control valve 14, 15 comprises a pair of manually operated push-button check valves and the outlets 5, 6 of the two pairs of valves are respectively connected through ball valves 7, 8 to lines 5<SP>1</SP> , 6<SP>1</SP> and also to opposite ends of conventional distributing valves in each of the two circuits containing the hydraulic loads. In operation and on opening say the right hand valves 14, 15 thereby pressurizing both lines 5<SP>1</SP>, 6<SP>1</SP>, switch valves 3, 4 are moved to position II so as to connect pump delivery line 17 to valve 9 which is thus moved to position II and thereby each pipe 10 is connected separately to its associated load through the distributing valve held open by pressure in lines 5, 6. When only one of valves 14, 15 is activated then one or other of valves 3, 4 remains in position I so that valve 9 is denied pressure fluid and remains in position I.
