Abstract
The invention relates to an expansion device for a refrigerant, in particular an expansion device to control the high-pressure level of an air conditioner. In accordance with the invention, it is provided that the expansion device (16) is a sliding seat valve (22). In addition, the invention relates to an air conditioner (10), in particular an air conditioner (10) for a motor vehicle, with a compressor (12), a condenser or gas cooler (14), an expansion device (16) as well as an evaporator (18). In accordance with the invention, it is proposed that the expansion device (16) is formed by at least one sliding seat valve (22).
Claims24
