Abstract
PURPOSE: To check fluctuations of controlling oil pressure by mounting a valve floating corresponding to oil temperature or a change of oil pressure in an oil hydraulic source in a hydraulic control valve for a hydraulic clutch so as to automatically adjust the quantity of escape oil.
CONSTITUTION: When an operating rod 24 is positioned upward, control oil from an oil hydraulic source 9 flows into a hydraulic clutch 20 through an inlet 2, a connecting groove 25 and an outlet 15 of a valve box 1 without pressure reduction to join a clutch. When the rod 24 is slightly lowered, the control oil flows from an outlet 16 into the clutch 20 through an inlet 3, a connecting hole 27 and the outer periphery of a floating valve 29. At this time, if oil pressure changes, the floating valve 29 travels, and small cavities 28 are opened depending upon the travel, so that the control oil is exhausted that much through an escape chest 13a and an escape port 11 so as to keep oil pressure constant. When the rod 24 is lowered to the full, the inlets 2, 3 are closed to raise the floating valve 29 to the full, resulting in disconnection of the clutch.
