Beschreibung
Zusammenfassung:	A flow path switching valve that can suppress deformation of the sealing surface and prevent valve leakage by reducing pressure load to avoid deformation of the high-pressure side slide valve body, and that contributes to improvement of efficiency of the heat-pump type air conditioning system is provided. In a flow path switching valve (1), a low-pressure side valve body (15B) is freely slidably fit to an outer side of a high-pressure side slide valve body (15A). An O-ring (18) that is an annular sealing member is provided between the high-pressure side slide valve body (15A) and the low-pressure side valve body (15B).
