Abstract
734,434. Hydraulic control systems; valves. CARBODIES, Ltd. Sept. 30, 1953 [Jan. 24, 1953], No. 2117/53. Classes 69 (2) and 135. A hydraulic system having jacks for operating a vehicle hood is provided with valves which are normally open so that the drop head may be moved by hand, and the jacks are operated in at least one direction by the closing of a valve. In one embodiment the hood is lowered by operating a switch 46 to energize a motor driving a pump 32 and to energize a solenoid 48 closing a valve 41. The pump 32 supplies a jack 30 for forwardly tilting a seat as described in Specification 710,371, [Group XXXII]. When the jack 30 is fully extended, fluid is admitted through a pipe 38 to the annular ends of cylinders 26c of the hood-operating jacks, retracting the jacks. The expelled fluid passes through a valve 43 to a reservoir 31. To raise the hood the switch 46 is operated to energize the motor and a solenoid 49 for closing the valve 43. In this case, after the jack 30 has fully tilted the seat forwardly, fluid is admitted to both ends of the cylinders 26c and the jacks are extended. On starting the pump 32, fluid is supplied to a valve 35 through a pipe 34. The fluid raises a piston 60, closing members 63, 64 and permitting communication between the pipe 34 and a pipe 36 through a passage 62. When the hood operating jacks have been actuated pressure develops in pipe 36 until piston 60 is moved to open members 63, 64 for the pump delivery to pass to the reservoir. When this occurs a valve 74 is unseated and contacts 70, 71 of a warning system are closed. In another embodiment separate inlet and exhaust valves are provided for each end of the cylinders 26c, and in a further embodiment single-acting jacks having a spring-operated return stroke are provided.
