Structure

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

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

A — type A
B — type B
1 — the piston
2 — a cuff
3 — the LSPV lever
4 — a sensor spring

5 — from primary camera of the main cylinder (a brake of back wheels)
6 — from the secondary camera of the main cylinder (a brake of forward wheels)
7 — to a brake of back wheels
8 — a pin
9 — an opening for a bolt
