129/5 Spring plate

129/6 Belt pulley

129/9 Solenoid

Position

Behind belt pulley of air pump

Task

When actuated, connecting the air pump to the belt pulley driven by the poly V-belt.

Design/function

The voltage for the air pump electromagnetic clutch is supplied through the secondary air injection relay.

A magnetic field is produced when current flows through the coil of the solenoid. Belt pulley and air pump are positively connected by the moving parts of the spring plate.
