油圧調整機構。 ・A clutch supply oil line is connected to the hydraulic oil pump via a switching valve, and each lubricating part is connected via a pressure regulating valve.
The pressure regulating valve is equipped with a loose-fitting valve mechanism for automatically adjusting the set pressure, a modulating valve is installed in the switching valve, and the operating part of the loose-fitting valve structure is connected to the pump via the modulating valve. During the period from the start of oil supply to the clutch supply oil path to the start of clutch press-contact operation, the modulating valve closes due to the pressure difference between the hydraulic oil pump and the clutch supply oil path, increasing the set pressure to the loose fitting valve mechanism. A hydraulic adjustment mechanism for a reduction/reversing machine, etc., characterized in that the supply of oil is stopped.・
