ELECTRONIC EXPANSION VALVE FOR REFRIGERATING CYCLE |
摘要 |
PURPOSE: An electronic expansion valve for a refrigerating cycle is provided to reduce a product size and manufacturing cost by using a smaller magnet for reducing a gap between a coil and the magnet by adopting a stepping motor incorporated with a stator winded with the coil and a rotator mounted with the magnet in a motor housing. CONSTITUTION: An electronic expansion valve for a refrigerating cycle includes a valve body(51) formed with a refrigerant inlet(513) and a refrigerant outlet(512) and provided with an orifice(511) between the inlet and the outlet, an opening and closing element(52) mounted in the valve body movable vertically and provided with a needle(525) for opening and closing the orifice, a driving element(53) coupled with the valve body and mounted with a motor(531) having a driving shaft(531d) for driving the opening and closing element, and a stopper element(54) disposed between the opening and closing element and the driving element for controlling upper and lower dead points of the opening and closing element. |
