摘要: It takes high skill to achieve maximum efficiency of construction equipment under the ever changing working conditions. The automatic implement control system helps maximize operator efficiency and convenience by allowing a predetermined angle, lift and/or tilt position of a work implement (40) to be stored in the memory of the controller (3). In operation, the implement (40) may be moved from that stored predetermined position to perform other functions. In an automatic mode, the controller (3) can return the implement (40) to that predetermined position at any time during the work cycle. A valve (15-70) is provided for selectively switching between manual and automatic modes.

摘要: A flow control valve comprising spool means and overload relief valve means built in the spool means. A filter is disposed on the upstream side of the relief valve means. When a hydraulic oil is passed through the filter, foreign materials are removed from the oil and the pulsation of the oil is inhibited or eliminated.
