19 AIR CONDITIONING VACUUM SOLENOID VALVE (VSV) Engine idling speed raising device is provided to enable cooler operation in a heavy traffic area. The VSV (vacuum solenoid valve) is a component part of this device. Construction of VSV is shown in Fig. on the right. Operation When switching off the air conditioner, theVSV opens to atmosphere side by compression spring. l F. I. P. lever allows it to return to the idle position. l When switching on the air conditioner,-current flows into the coil, and the VSV opens to vacuum source by magnetic force. Thus, the vacuum will act on the diaphragm of actuator installed on F. I. P. l With the help of actuator the accelerator lever is pushed to get higher idling rpm.
