Kylning av hydraulsystem för vibratiorplattor

摘要

The purpose of the present invention is to cool the hydraulic fluid in a hydraulic-powered vibrating compactor by providing the hydraulic pump (6) of the compactor with a through shaft with a fan wheel (7) mounted on the free end (8), which fan wheel is located so as to draw cooling air (15) through a duct (10) formed by a tunnel-shaped hydraulic fluid reservoir (9).
