Abstract
PURPOSE: To provide a hydraulic buffer suited for a power shift clutch of industrial machinery operating positively by sending a portion of oil having pressure raised during operation of the clutch to an accumulator between a clutch change-over valve and oil pressure supply to change over controllably the pressure rise even quickly.
CONSTITUTION: When a change-over valve 26 is changed over to cmmunicate an oil path 23 to a clutch 27, oil is supplied to the clutch 27 through an oil path 18, groove 37, first oil path 61 and bypass 45, and a clutch piston abuts against a frictional plate to raise oil ressure. Thus, a spool 30 is moved right by pressure rise of oil in a operating chamber 38, and a portion of the oil flows into an accumulator 32 through oil paths 46, 62. Oil amount to the clutch 27 is reduced to provide smooth engagement of the clutch. Further, the spool 30 is moved left to sent oil from an oil path 63 to a tank M and from the oil path 46 to the clutch 27. By the next change-over of the clutch is lowered oil pressure to move quickly the spool 30 right. Thus, the clutch can be operated even by quick repetitive change-over operation.
