Operation of clutch pressure-relief valve (4V5)
Text-module
Clutch pressure-relief valve 4V5
Text-module
Clutch pressure-relief valve is mounted in valve unit which also contains connection between
high-pressure circuit PH and tank.
Clutch valve also limits max. high pressure PH to 500 bar (+/- 20 bar).
Clutch valve closes high-pressure circuit to tank when clutch pedal is not actuated.
When clutch pedal is actuated, clutch valve opens, and high pressure PH is discharged via tank
connection.
Discharge of high pressure (interruption in tractive power) is therefore proportional to clutch pedal
travel (comparable to mechanical clutch).
Clutch pedal fully depressed, high pressure PH = 0 bar .
Max. high pressure and high-pressure build-up depend on operation and tightness against
leaks of clutch pressure-relief valve (4V5).
