Control valve for vehicle air-conditioning system

摘要

The control valve (1) for the vehicle air conditioning system, ventilation system or heating system is operated by a servo cylinder (4) linked to the inlet manifold. A return spring (6) resets the valve after the servo setting has been completed. A flow restriction (11) vents the servo. The flow restriction comprises tube (11) fitted to the vent duct (10) of the control valve (8) for the servo. It can be a flow restriction insert into the duct and has a diameter of 0.4 to 0.6 mm.
