062511000 | Fixed restrictor | 10 |
20080229781 | Flow Control - The problems of prior compressor structures relying upon conventional check valves are obviated by using, instead, flow control passages which operate to control flow while avoiding mechanical moving elements which may become problematical. | 09-25-2008 |
20080236193 | Motor-operated selector valve and refrigeration cycle device for refrigerators - A motor-operated selector valve relating to refrigerating technology is provided. There are disadvantages, such as complicated assembly structure, big noise, vulnerability to interferences etc., in prior art. In the present invention, a slider is controlled by a stepper motor so as to be rotatablely displaced among four positions on a flat bottom surface of a valve seat. Three outlets on the flat bottom surface are communicated with a normal open inlet in the valve seat via flow-guiding orifices in the slider respectively. In the first working position, the first outlet and the third outlet are in communication with the normal open inlet at the same time; in the second working position, the second outlet is in communication with the normal open inlet; in the third working position, the third outlet is in communication with the normal open inlet; in the fourth working position, the first outlet is in communication with the normal open inlet. The technical solution employs the driving means of rotary displacement, thereby the action noise can be less than 30 dB (A) at a distance of 30 cm; and power supply can be cut off after the switch among the working states, as a stable working state can be ensured through the self-maintaining function of magnetic poles and the magnetic rotor of the stepper motor, as a result, energy consumption of the valve itself is reduced. | 10-02-2008 |
