Abstract

1,068,867. Hydraulic apparatus. PREROVSKE STROJIRNY NARODNI PODNIK. Aug. 4, 1964, No. 31542/64. Heading F1P. [Also in Division F2] A control mechanism for a machine operated by hydraulic motors comprises a valve bank 1 supplied with fluid from a pump 28 and a valve bank 8 supplied with fluid from a pump 29. The bank 1 comprises a valve 3 controlling a motor 33, a valve 4 controlling a motor 35 and a valve 6 controlling a motor 36, the valves being provided with by-pass passages to supply the valve 6 through passage 31. The bank 8 is similar to the bank 1, its valves 10, 11 and 13 controlling the motors 34, 36, 35. Thus the motors 35, 36 can each be actuated by one supply or the other, or by both supplies together. The valves 4, 13 and 6, 11 may each be actuated by a lever controlling a cam-shaft, the cams being shaped that movement of the lever actuates first the valve 11, say and then the valve 6.
