LSPV (Load Sensing Proportioning Valve) Assembly Construction: Construction
WARNING: This page is about a different car, the 2004 Suzuki Vitara. However, it is still accessible from the selected car via links, so may be relevant.
The LSPV components are grouped into three sections ("A", "B", "C" as shown in the figure) as follows.
"A": Sensor section
The main parts in this section are a lever and a spring which senses variation in the vehicle height as affected by the loaded condition and converts it into the load.
"B": Hydraulic pressure control section
Included in this section are a stepped plunger and valve mechanism to execute proportional control.
"C": Fail-safe section
The main parts in this section are a chamber which draws in the hydraulic pressure from the front wheel brake system and a fail-safe piston which releases the valve mechanism in the control section connected to the rear wheel brake, should any failure occur in the front wheel brake system.
