SELF-CONTAINED REGULATING VALVE, AND COMPRESSION TYPE REFRIGERATING MACHINE HAVING THE SAME

摘要

Independent control valve is provided with a spool 13 which moves in an axial direction in the inner space of the cylindrical valve body (11). The pressure of one (P ₁₎ is acting on the end face of the spool 13, the other pressure (P ₂₎ acts on the other end face of the spool 13. In the spool 13 is provided with a through hole (13a). Of one of the pressure (P ₁₎ and when the other pressure the pressure difference between (P _2), the difference to exceed the setting value, the through-holes (13a) and independent adjustment the pipe 12 connected to the valve body 11 communicating with the valve in an open state It becomes.
