Abstract

There is described a pressure regulating valve for a refrigerating plant, having a slider member that can be moved relative to a guide by means of a drive device, with variable throttle resistance being created between the guide and the slider member. The purpose of such a valve is to be able to control refrigerant over a relatively large throughput range, and the valve should be able to be manufactured inexpensively. For that purpose, the slider member and the guide co-operate in two sections of their movement relative to one another according to different valve principles.
