Title: Built-in check valve type solenoid valve
Inventor: SATOU MASAHIRO
IPC: F16K31/06
Filed: 1979-11-15
Abstract: PURPOSE: To try reducing cost and simplifying piping operation, by manufacturing in a unit building-in a check valve mechanism in the solenoid valve body.  
     CONSTITUTION: When the refrigerant flows from the inlet 2 to the outlet 3, the valve body 13 is pushed to the valve seat 12 to shut the branch passage 18 by the pressure of the refrigerant. Therefore the refrigerant moves a movable piece 11 up due to energizing to the magnetic coil 10, flowing into the outlet 3 through the main passage 7 with a valve hole 9 opened. On the other hand, when the refrigerant flows in opposite directions, the valve body 13 leaves from the valve seat 12 to open the branch passage 8 by its pressure. Thereby, the refrigerant reaches the inlet 2 through the branch passage 8. In this time, the valve body 13 is supported to slide freely at the end of a spring pin 14, with reflux of refrigerant, the refrigerant moves along the spring pin 14, jumping up of the valve body 13 can be prevented with reflux of refrigerant.
