Abstract
The invention is directed to an arrangement for cooling the hydraulic fluid in a hydraulic-powered vibrating compactor. The arrangement includes a hydraulic pump (6) of the compactor. The hydraulic pump (6) is provided with a through shaft having a fan wheel (7) mounted on the free end (8) thereof. The fan wheel (7) is located to draw cooling air (15) through a duct (10) formed by a tunnel-shaped hydraulic fluid reservoir (9). This arrangement reduces the temperature of the hydraulic fluid in the hydraulic-powered vibrating compactor.
