Abstract (en)
[origin: EP0701067A2] The system comprises a tank for the hydraulic oil and to which one or more rams are connected via a forwarding pipe, a filter and a distributor valve. A return pipe runs from the valve back to the tank. A valve functioning dependent on temp. is connected between the forwarding and return pipes. The valve outlet is arranged between the tank and the pump, and it can be arranged to open below a predetermined temp. which can be determined dependent on the flow rate through the filter and/or the viscosity of the hydraulic oil. The valve can be spring-loaded, the loading being temp. dependent.
