发明名称 OIL-FILLED BUFFER OF ELEVATOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a highly reliable oil-filled buffer of an elevator which suitably maintains plunger inner pressure while avoiding a cost increase while eliminating the scattering of hydraulic fluids to surroundings. <P>SOLUTION: The oil-filled buffer 1 of the elevator includes a vertically extending hollow cylinder 3, a hollow plunger 5 provided so as to be extended and contracted in the vertical direction to the cylinder, an elastic member 7 for imparting an elastic force in an extending direction to the plunger, and an oil receiver 9 arranged integrally to the plunger. The oil receiver is opened at the upper part, and the inner side of the oil receiver and the inner side of the plunger are made to communicate with each other so as to distribute oil. <P>COPYRIGHT: (C)2013,JPO&INPIT
