Electrically operated valve

An electrically operated valve comprising:

• a valve main body having a valve chamber which is communicated with an inflow passage introducing a refrigerant and an outflow passage discharging the refrigerant;
• a valve body which changes a flow rate of the refrigerant by moving forward and backward with respect to a valve seat formed within the valve chamber between a valve close state seating on the valve seat and a valve open state separating from the valve seat;
• an electric motor which drives the valve body;
• a control board on which an electronic component controlling the electric motor is mounted;
• a board storage portion for making it possible the control board to be stored in a sealed state;
• and
• a connector portion having an external portion connecting terminal for an electrical connection to the outside and a sealing structure sealed by fitting to a mating connector,
• wherein the board storage portion includes:
• a case portion having an opening for making them possible the control board to be stored in an internal portion thereof and the board to be installed in the internal portion thereof;
• and
• a lid body for occluding the opening,
• wherein the connector portion and the lid body are integrally formed as a lid body with connector portion, and
• wherein the electrically operated valve further comprises a communicating passage for communicating the board storage portion with the connector portion,
• wherein the communicating passage is bent perpendicularly between one opening and the other opening, and
• wherein the board storage portion comes to the sealed state when the mating connector is fitted to the connector portion.

A stator making it possible to be disposed in an electric motor driving a valve body of an electrically operated valve,

• wherein the stator includes:
• a control board mounted with an electronic component controlling the electric motor;
• a board storage portion for making it possible the control board to be stored in a sealed state;
• a connector portion having an external connection terminal for an electrical connection to the outside and having a sealing structure sealed by fitting to a mating connector;
• and
• a communicating passage for communicating the board storage portion and the connector portion, and
• wherein the board storage portion comes to the sealed state when the mating connector is fitted to the connector portion.
