Title:
COOLING DEVICE OF HYDRAULIC GEAR
Document Type and Number:
Japanese Patent JPS604608
Kind Code:
A
Abstract:
PURPOSE:To prevent a working environment from worsening by a high temperature so as to improve operation efficiency, by interposing a flow path of oil, which comprises a water vessel having a heat exchange flow path of oil in the inside and enabling water to be replaced, in a part of the hydraulic circuit. CONSTITUTION:A water vessel 7, in which a heat exchange flow path 8 of oil is provided and water can be replaced, is provided in a hydraulic circuit 3 between an oil tank 2 and a hydraulic actuator 1. In this way, cooling water in the water vessel once storing heat generated from a hydraulic equipment is discharged in a place detached from a field of construction work or the like, and then the cooling water can be supplied. Accordingly, a high temperature is not caused in the field of construction work or the like, and a working environment can be prevented from worsening.
