The LSPV components can be divided into three groups as follows.

  • "A": sensor block
    • The main parts of this block - lever and a spring which react to change in vehicle height in the loaded condition and will transform it to loading.
  • "B": control unit hydraulic pressure
    • The step piston and the mechanism of the valve which is carrying out linear regulation enters into this block.
  • "C": the failure-safe block keeping working capacity at refusal of separate elements.
    • The main parts of this block – the chamber which reduces hydraulic pressure from brake system of forward wheels and the failure-safe piston which releases the valve mechanism in the control unit, connected to a brake of a back wheel in case of any malfunctions in brake system of forward wheels.
