ABSTRACT:
A flow path switching apparatus in an automatic regulating valve includes a base having a fluid inlet and a fluid outlet which are connected to pipes, and an automatic regulating valve portion having an inflow hole and an outflow hole for a fluid to be controlled. The automatic regulating valve portion is pivotally mounted on the base. A pair of inflow and outflow communication paths for causing the fluid inlet to communicate with the inflow hole and causing the fluid outlet to communicate with the outflow hole are formed in the automatic regulating valve portion. The fluid inlet is connected to or disconnected from the fluid outlet in accordance with a pivot position of the automatic flow regulating valve portion.
