COOLING DEVICE OF HYDRAULIC SYSTEM FOR VIBRATION-TYPE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To improve the cooling performance when a pressure medium liquid in a hydraulic vibration-type compressor is cooled, by exhausting the cooling air cooled by circulating the air in a tunnel-type pressure medium liquid storing tank to the atmosphere through a space between a top cover of a compressor casing and a roof of the pressure medium liquid storing tank. SOLUTION: An element 3 attached to a chassis 1 by a plurality of vibration damping units 4, is mounted on a bottom plate 2 of a vibration-type compressor, a hydraulic pump 6 is driven by an internal combustion engine 5 mounted on this chassis 1, and a fan wheel 7 is rotated. Further a hydraulic storage tank 9 having a structure that a duct 10 is formed by an internal side wall 11 and the air is sucked through the duct 10 by the rotation of the fan wheel 7, is mounted on the chassis 1, and the sucked air is upwardly directed through a baffle 12, and passed between a top part 13 of a compressor casing and a roof of the pressure medium storage tank 9. Then the air is exhausted into the atmosphere through a lattice of a side surface 14 of the compressor casing facing to a handle 16.
