20140174567 | LIQUEFIED PETROLEUM GAS (LPG) BOMBE VALVE APPARATUS - An LPG bombe valve apparatus includes a valve body, a check valve, a cam, a cam rod and a converting mechanism. More specifically, the valve body is disposed in an LPG bombe and having a fuel channel therein for discharging fuel supplied from an LPG line to the LPG bombe. The check valve is disposed in the fuel channel, with one end supported by an elastic member to be pressed to close the fuel channel. The cam is disposed within the check valve, and the cam rod connects the cam with the check valve and controls opening/closing of the check valve in accordance with rotation of the cam. A converting mechanism has both ends connected to the cam and a float of the LPG bombe converting vertical motion of the float into rotational motion of the cam. | 06-26-2014 |
20140184008 | BRUSHLESS DIRECT CURRENT (BLDC) MOTOR - A brushless direct current (BLDC) motor includes a magnet which includes N poles and S poles extending in the up-down direction. The N poles and S poles are arranged to alternate with each other, surround an exterior of a shaft, and have a cylindrical shape when assembled. The magnet has upper and lower tapered portions in upper and lower portions thereof, with the diameter decreasing in the direction toward opposite ends, and a fixing center groove formed in the middle thereof. Fixing caps respectively have inclined portions at positions corresponding to the upper and lower tapered portions of the magnet so that the tapered portions fit into the inclined portions, thereby fixing an axial position of the magnet. A center ring is fitted into the center groove of the magnet in order to prevent the magnet from being dislodged while a rotor is rotating. | 07-03-2014 |
