Filed: 1999-12-29
Abstract: PURPOSE: Oil feed structure of a linear compressor is provided to cool a discharge cover for discharging refrigerant gas compressed by rectilinear reciprocating of a piston as well as to cool a discharge part of a cylinder smoothly. CONSTITUTION: A discharge oil circulating path is formed to cool a discharge part with circulating refrigerant gas and to diffuse the cooling oil of the discharge part to a discharge cover(60). A compression oil circulating path is formed to cool the middle part of a cylinder(20) for compressing refrigerant gas and to diffuse the cooling oil of the middle part to the discharge cover. Oil pumped from an oil feeder flows through the discharge oil circulating path to cool the discharge part for compression and discharge of refrigerant gas. Then, the oil is diffused to the discharge cover. The discharge cover and the discharge part is cooled effectively. A part of the pumped oil flows through the compression oil circulating path to cool the cylinder. The oil is diffused to the discharge cover. The discharge cover as well as the cylinder are cooled effectively.

Title: Variable valve timing system
Inventor: CHOI JEONG HWAN
IPC: F01L1/34
Filed: 1999-12-30
Abstract: PURPOSE: A timing system for a variable valve is provided to vary valve timing and a valve lift according to operation condition of an engine. CONSTITUTION: Oil is inputted through a main galley of a cylinder head. Then, hydraulic pressure is controlled through a motor according to an engine condition detected by an ECU(Electronic Control Unit). The oil is supplied to first and second chambers(21,22) of a hydraulic lash adjust(20). Locations of plungers(23,24) are varied by a balancing condition of force in first and second chambers while being located in a cam base circle by the oil and a return spring(28) in the first chamber. In case of increase in volume of the second chamber, a valve(14) is opened rapidly to increase a valve lift. In case of decrease in volume of the second chamber, the valve is slowly opened to reduce the valve lift.

Abstract: PURPOSE: A blow-by gas recirculation system is provided to prevent the increase of carbon and exhaust gas and the waste of oil by completely removing oil and impurities in the oil. CONSTITUTION: A blow-by gas recirculation system comprises a connecting pipe(5) connecting a crankcase(3) with a surge tank(4), a PCV(Positive Crankcase Ventilation) valve(6) and an oil separating chamber(7) prepared in the middle of the connecting pipe. A part of the connecting pipe passing through the oil separating chamber is formed in a coil-shaped spiral separating tube, and a U-shaped siphon pipe is connected to the lower portion of the oil separating chamber. The siphon tube is filled with oil and is connected with an oil pan or the crankcase. Plural oil drain holes are formed on the outer circumference of the threaded separating tube. Upon driving an engine, the PCV valve is opened and blow-by gas accumulated in the crankcase flows into the surge tank. Centrifugal force is generated by the flow velocity of the blow-by gas passing through the threaded separating tube, and the oil and impurities in the blow-by gas are leaned to the outer portion of the tube. Then, oil and impurities scatter via the oil drain holes and recovers in the oil separating chamber. Therefore, clean blow-by gas is supplied to a cylinder via the surge tank. As the siphon tube is filled with oil, a counterflow of blow-by gas, impurities and oil to the oil separating chamber from the crankcase is prevented.

Abstract: 본 발명은 이동통신 교환기의 메모리 상 PLD 검증 방법을 제공하기 위한 것으로, 이러한 본 발명은 운영중인 교환기의 OMP에서 PLD 파손 여부 진단 명령을 수신하게 되면, OMP 메모리 상에 로딩된 PLD 영역 중에서 PLD header 영역, GDIR 영역, RDIR 영역, RDIC 영역 및 relation의 파손 여부를 checksum값을 이용하여 순차적으로 검증한다. 그래서 OMP 메모리 상 PLD의 파손 여부를 교환기 운용중에 자동적인 방법으로 즉각적이고도 용이하게 진단할 수 있도록 하여 PLD의 무결성을 보장하고 시스템의 신뢰성 및 안정성을 높일 수 있도록 한 이동통신 교환기의 메모리 상 PLD 검증 방법을 제공하는 데 있다.
