Abstract
1303600 Fluid pressure motor control circuits INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 19 April 1971 [12 March 1970] 23787/71 Heading F1P The head end of a pressurized fluid e.g. hydraulic or pneumatic actuator 53 for controlling an oil-well valve (not shown) is connected through a two-position fluid actuated spool valve 50 and through a two-position solenoid spool valve 25 to hydraulic accumulators 38 or to a return reservoir 70 according to the setting of solenoid valve 25, and the rod end of actuator 53 is similarly connected by a two-position fluid actuated valve 56 and valve 25; the actuating fluid pressure for valves 50, 56 being derived from accumulators 38 through a line 58 whereby in the event of an undue low pressure in said accumulators the valves 50, 56 are each displaced by an associated spring to a position in which the head end of the actuator 53 is connected to a reserve accumulator 40, the rod end is connected to return and the oil well valve is closed. All three accumulators 38, 40 are charged by an electric motor driven pump 34 delivering past check valves 41, 42. A branch 61 of hydraulic line 58 includes a normally closed relief valve 62 which when an electrical warning signal energizes its solenoid 64 opens and vents line 58 and causes valves 50, 56 to isolate accumulators 38 from actuator 53 and connect accumulator 40 thereto so as to close the oil well valve.
