Abrégé
(EN)
The present cooling system (21) provides a limited flow rate to clutches (26, 28) (for example in industrial vehicles) during disengagement and provides additional cooling flow to the clutches (26, 28) during partial engagement and controls the pressure level of the fluid from the source of cooling fluid (42) by operation of a valve mechanism (46) which is responsive to a control mechanism (110). Upon full engagement, the valve mechanism (46) automatically reduces the volume of cooling fluid to the clutches (26, 28) and simultaneously reduces the pressure level of the cooling flow from the source of cooling fluid (42). This cooling system provides the needed volume of cooling fluid during partial engagement of the clutches (26, 28) and also reduces the volume of cooling fluid during disengagement to reduce drag forces while further reducing the volume of cooling fluid during full engagement to conserve horsepower.
