VALVOLA DI INVERSIONE IN PARTICOLA RE PER COMPRESSORE DI IMPIANTI RE FRIEGERANTI

摘要

The four-way reversing valve is utilized in refrigerating systems for heat pump applications to interchange the heating and cooling effects of the evaporator and condenser. The three-way pilot valve controls application of high or low system pressure to the end of the chamber adjacent the large piston. The different areas of the two pistons result in movement of the slide valve to the left (both modifications) when high pressure is applied and to the right when low pressure is applied.
