Abstract
PURPOSE: To simplify and reduce the size of a device for cooling oil of a hydraulic elevator for preventing oil temperature from excessively increasing by thermally exchanging oil to a tank by introducing part of return oil to cooling unit directly by utilizing return energy of the oil.
CONSTITUTION: The oil in a cylinder 7 of a hydraulic elevator operated by a hydraulic pump 1 when a plunger 6 is downwardly moved is returned from a brake valve 8 through routes of arrows 9, 10 to a tank 11 with variable return throttle 27 interposed in the main circuit of return oil flow 10 to thereby branch part of return oil as bypass flow 22 to a cooling unit 20. When the oil temperature reaches predetermined value, a solenoid valve 21 is opened by a temperature switch 31 to branch the bypass flow 22 into motor flow 23 and cooling flow 24 to thereby cool the oil via a radiator 26 by a fan 28 driven by a hydraulic motor 37.
