Claims

[Scope of utility model registration request]

In a drive circuit having an electromagnetic clutch for a refrigerant compressor driven by an automobile engine, a cut relay is inserted in the operating circuit of the electromagnetic clutch, and a normally open vacuum switch and a normally closed vacuum switch are included in the excitation circuit of the cut relay. are inserted in series, the normally open vacuum switch is communicated with the intake manifold via a vacuum switching valve, and the normally closed vacuum switch is also communicated with the intake manifold, so that both vacuum switches and the intake manifold are connected. A check valve with an orifice that can open and close both vacuum switches with a time delay relative to each other is inserted into the connecting vacuum pipe, and a normally open accelerator switch is inserted into the operating circuit of the vacuum switching valve, and A near-conditioner control device for an automobile, characterized in that a vacuum pipe of a normally open vacuum switch is provided with an air chamber that communicates directly with the switch.
