| 20110084224 | ELECTRONIC EXPANSION VALVE - The present invention provides an electronic expansion valve, comprising a leading screw, a valve needle and a valve needle sleeve. It further comprises: a washer provided in an annular groove, which is provided at the lower end of the leading screw in the circumferential direction, and a thickness of the washer is less than a width of the annular groove; the valve needle sleeve abuts against the upper surface of the washer and is fixedly connected with the valve needle; and a spring is provided between the washer and the valve needle. By arranging the washer in the annular groove provided at the lower end of the leading screw in the circumferential direction, with the thickness of the washer being less than the width of the annular groove, and by arranging the spring between the valve needle and the washer, the washer is enabled to rotate around the annular groove in the circumferential direction and move up and down in the annular groove, improving the reliability of the electronic expansion valve. | 04-14-2011 |
| 20110012039 | ELECTRIC CONTROL VALVE AND VALVE BODY DEVICE THEREOF - The present invention discloses a valve body device for an electric control valve comprising a valve seat ( | 01-20-2011 |
| 20110012038 | ELECTRONIC EXPANSION VALVE - Embodiments of the invention provide an electronic expansion valve, including a magnetic rotor and a screw rod, and further including an output shaft. The magnetic rotor is surroundingly provided on the output shaft, and the output shaft is slidably connected to the screw rod in an axial direction and drivably connected to the screw rod in a circumferential direction. Since the output shaft is slidably connected to the screw rod in an axial direction and drivably connected to the screw rod in a circumferential direction, the magnetic rotor does not subject to an axial force transmitted by the screw rod and rotates flexibly. | 01-20-2011 |
| 20100328004 | ELECTROMAGNETIC COIL DEVICE - The present invention discloses an electromagnetic coil device including a coil body having a connection terminal portion projecting from a circumferential surface of the coil body, a buckle having a positioning flat plate portion and an inserting flat plate portion fixedly connected to the positioning flat plate portion. The inserting flat plate portion is pottedly connected to the connection terminal portion with potting material. The electromagnetic coil device can, on the one hand, reduce the manufacturing cost and improve the reliability of the connection between the coil body and the buckle, and on the other hand, prevent the coil body from being damaged by welding and thus improve the life thereof. | 12-30-2010 |
| 20100301984 | ELECTROMAGNETIC COIL MEANS - The present invention discloses an electromagnetic coil means, comprising a terminal part and pins passing through the terminal part, wherein the pins are divided into a first group of pins connected with an upper coil stator and a second group of pins connected with a lower coil stator which are spaced apart from each other; the first group of pins comprises first outer sections with first head portions and first inner sections with first root portions; the second group of pins comprising second outer sections with second head portion and second inner sections with second root portions; the first and second head portions extend out from a pin leading-out surface of the terminal part, characterized in that, at least one group of the first and second groups of pins are bent, and a distance between adjacent said first and second head portions is larger than that between adjacent said first and second root portions. By this electromagnetic coil means, the distance of solder joints between adjacent head portions of pins is increased, thus the insulation performance between the solder joints is improved. | 12-02-2010 |
