Abstract
PURPOSE: To shorten the oil pressure piping and reduce the fluid resistance by boring a flow passage on a trunnion stafts fixed at the base part of a hydraulic cylinder and constructing said trunnion shaft on an aggregated pipe freely rotatably and fitting a flow-rate control valve integrally with the aggregated pipe.
CONSTITUTION: Trunnion shafts 8 and 8' are fixed at the base part of hydralic cylinders 5 and 5', and the flow passages 9 and 9' which allows oil to flow into and out inside and outside the hydraulic cylinders 5 and 5' are bored on the shaft center of the trunnion shafts 8 and 8'. An aggregated pipe 10 is fitted on the brackets 4 and 4', and on the aggeregated pipe 10, one end of the trunnion shaft 8 is axially suspended freely rotatably. With this aggregated pipe 10, is integrally fitted a flow-rate control valve 15 which controls the flow rate constant which flows out from the aggregated pipe 10. Thus, oil pressure piping can be shortened, and the fluid resistance can be reduced.
