Abstract: 609,713. Hydraulic machines. EVERNDEN, H. 1. F. Oct. 20, 1944, No. 20395. [Class 69 (ii)] [Also in Group XXIV] Brake or other actuating cylinders 2 of a change-speed epicyclic-gear B on a vehicle, are supplied with oil-pressure through a selectorvalve 1 by an oil-pump 6, driven by the output turbine-runner 4 of a hydraulic torque-converter A or coupling through which the gear is driven, and delivering, through a spring-loaded non-return valve 14, to a spring-loaded accumulator 15, provided with a valve 23 which isolates the accumulator from the selector-valve 1 until the necessary pressure is developed, whereupon it is opened by the accumulator piston-rod and thereafter maintained open by delivery pressure acting through a duct 26 on a spring-loaded piston 27 on the valve. The oil-pump 6 is capable of providing the desired operating pressure at idling speeds, and is also connected directly to the selector-valve 1 through a spring- opened, pressure-closed valve 9, so that on starting, it first fills the system, and at a predetermined low pressure (10 lb./sq. in.) the valve 9 closes, but the pump 6 continues to supply pressure to the accumulator, and at a predetermined pressure the isolating-valve 23 opens. The pressure thereby applied to the selected brake in the gear B brings the turborunner 4, and so the oil pump 6 to rest, but the accumulator 15 maintains sufficient brakeoperating pressure to get the vehicle in motion, after which an additional smaller oil-pump 18, driven by the vehicle axle, takes over and maintains the accumulator filled. The deliveryline from each pump 6, 18 to the accumulator 15 includes pressure-relief and non-return valves 12, 19 and 14, 20, and the delivery of the pump 18 also operates, through a line 21, a suction cut-off valve 7 in the supply-line of the larger pump 6 to avoid power-loss and oilheating in the larger pump after the smaller vehicle-driven pump has developed sufficient pressure to take over.
