General information on refrigerant circuit<br />

Página 3 de 21<br />

The A/C compressor extracts the refrigerant gas from the<br />

evaporator, compresses it and relays it to the condenser.<br />

Note:<br />

- The A/C compressor contains refrigerant oil, which can be<br />

mixed with refrigerant R134a under any temperature.<br />

- The refrigerant for which the A/C compressor is designed<br />

is listed on the manufacturers plate. A regulator valve<br />

regulates pressure within the specified range (control<br />

characteristics) on the low pressure side.<br />

- In this A/C compressor, the regulator valve is activated<br />

from outside.<br />

- Engine should only be started when the refrigerant circuit<br />

is completely assembled 00-1, Basic rules for working<br />

on refrigerant circuit .<br />

- The A/C compressor is equipped with a protected oil<br />

supply, this prevents A/C compressor damage in the event<br />

that the system is empty. This means that approx.40 to 50<br />

cm 3 of refrigerant oil remains in the A/C compressor.<br />

A/C compressor without A/C clutch with torsionelastic<br />

clutch<br />

A/C compressor is driven directly by the power steering<br />

vane pump.<br />

An overload safeguard is installed on drive shaft of A/C<br />

compressor which shears off when A/C compressor locks<br />

up so that power steering vane pump remains functional.<br />
