| 20120070322 | ELECTRIC MOTOR-DRIVEN COMPRESSOR FOR VEHICLE - Disclosed is an electric motor-driven compressor having a structure capable of improving the performance of an electric motor of the electric motor-driven compressor for the vehicle. The electric motor-driven compressor has an angle which is formed by two straight lines passing through a center of the rotor and making contact with both end portions of one permanent magnet, and is in a range of about 48.7° to about 51°. The cogging torque and the torque ripples are minimized, the power of the electric motor is improved, and the electric motor is easily controlled. | 03-22-2012 |
| 20120070321 | COMPRESSOR FOR VEHICLE - Disclosed is a motor-driven compressor for a vehicle adapted to fix a connector of an electric motor for a vehicle compressor. The compressor for a vehicle includes a rotor configured be rotated by an electromagnetic force generated when a current flow through a coil, a stator having at least one connector fixing slot, and a connector having a body fixed to the connector fixing slot. | 03-22-2012 |
| 20120036782 | Door Actuator for HVAC System of Vehicle - A door actuator for an HVAC system of a vehicle includes a driving motor having a worm wheel and accommodated within a casing. An actuating gear has on an outer circumference thereof a worm thread that engages with the worm wheel, with an actuating thread being provided on a surface of the actuating gear. A change gear unit is hinged to the casing and rotatably engages with the actuating thread part. A solenoid unit rotates the change gear unit in a first or second direction. A first driving gear is provided at a predetermined position of the casing to engage with the change gear unit rotating in the first direction. A second driving gear is provided at a predetermined position of the casing to engage with the change gear unit rotating in the second direction. | 02-16-2012 |
| 20090136364 | Compressor - The present invention relates to a compressor, which includes a main refrigerant supply channel for supplying refrigerant by passing through the inside of a driving shaft and an auxiliary refrigerant supply channel for supplying refrigerant by passing through a suction chamber of front and rear housings and a slot of the driving shaft after passing through cylinder blocks in order to supply the refrigerant inhaled into a swash plate chamber to cylinder bores, thereby enhancing performance and lubricating ability of a driving shaft seal area since the refrigerant of the swash plate chamber can be used effectively. | 05-28-2009 |
