When the seize pedal in a howo truck is stepped on, the hydraulic oil from the seize booster cylinder enters the interior hollow space of the booster thru the oil pipe. As the pedal stroke boosts, the quantity of oil getting into the booster increases, and the strain of oil increases.

At this moment, the hydraulic oil forces the piston and the bottom rod diaphragm meeting to transport to the proper, and the exhaust on the remaining of the middle rod is blocked via way of means of the carry valve, and the valve is opened. So that as compressed air meeting as the outlet shop of the poppet valve increases, the hollow space of the bottom rod diaphragm meeting as the outlet push of the poppet valve increases, the compressed air forces the electricity piston, hydraulic piston, push rod one to transport the proper and pressurize the seize launch for to transport.

So that the Sinotruk Howo Clutch booster cylinder wg9725230041 launch bearing pushes the lever backing ring ahead in order that the seize booster is disengaged. When the seize pedal of the vehcile is released, the strain of oil drops. Under the motion of the plate spring strain, the frenzy rod, electricity piston, push rod and hydraulic are reversely pushed. The compressed air motives the rod diaphragm meeting to transport existence and the poppet is returning.

It’s closed beneath the motion of the location spring and the compressed air in the suitable chamber of the diaphragm and left chamber of the electricity piston is discharged into the encompassing thru the vent plug. Below the motion of hydraulic piston returns, push rod and the hydraulic oil flows returned into the Sinotruk Howo Clutch booster cylinder wg9725230041.
