Abstract

PURPOSE: To reduce a starting shock and shorten a time lag so that heavy work can be started immediately after engagement of a friction plate by raising the pressure of working oil gradually first and then sharply after completion of engagement of the friction plate.
CONSTITUTION: When the main speed-change lever is shifted from neutral, pressure oil is supplied to the cylinder of each oil-hydraulic clutch through the intermediary of a selector valve, while also entering the port 18 of a pressure control valve A. And, a spool 12 being moved to the right, the pressure oil is drained to the port of a relief valve. However, the pressure oil in a port 19 gets in gradually from a throttle orifice 22, pushing a spool 13 to the left and further pushing a spring 15, and therefore the spool 12 is moved to the left, whereby the pressure of the pressure oil is raised. From the point of time when the spool 13 contacts with a spring 14, elastic modulus starts to change and the moving velocity on the left side of the spool 12 increases and thereby the pressure of the pressure oil rises sharply.
